[HOW TO] 8L45 - 8 Speed Transmission Fluid & Filter Change for 2017-2022 Chevy Colorado & GMC Canyon

The 8L45 fluid change is pretty straight forward. You will replace approximately 6 quarts of fluid that is in the pan. Make sure you are on a level surface when doing this procedure. This procedure will be the same for 2017+ Chevy Colorado's and GMC Canyons that are equipped with the 3.6L V6 motor and the 8 Speed Transmission. It's important to note, that it's OK to add slightly more fluid than necessary when you refill the transmission. When you do the fluid level check procedure and remove the standpipe plug at operating temp, the pan will drain down to the correct level. Then you can reinstall the plug and be good to go.
READ THIS DOCUMENT FIRST BEFORE ATTEMPTING THIS PROCEDURE.

Note: While this procedure was performed on an 8 Speed 8L45 transmission, however the 6 speed 6L50 transmission will have a very similar fluid change process. However, it will use a different fluid and filter.

IMPORTANT READ HERE: It's ok to slighly overfill the trans on your initial refill. Because the excess fluid will drain out of the standpipe when you do the level check with the transmission at operating temperature. I added more fluid and rechecked the trans the day after this video to make sure I had enough fluid in it.

[@Joe4USMC]

@@zbandick He showed a "fluid change" as opposed to a fluid flush. In the 8L45, if you perform a fluid change, approximately 1/2 of the total capacity is changed. The total system capacity, including what's trapped in the torque converter, is 11.0 quarts. He's now got approx 1/2 new ATF, and 1/2 old ATF. If you perform this for a 2nd time, you'll have 75% new. A 3rd time will be 88% new. A 4th time would be 94% new.

[@fondupot]

Quik tip that’s not apparent in the video. You can overfill the transmission fluid, and then when you do the temp/level check the excess fluid will come out. So it’s ok to overfill it slightly to make sure you put enough in. In my video I didn’t explain that very good.

Perfectly well made video tutorial, I’m definitely knocking this out this weekend for sure! Thank you!🙏🏽

[@fondupot]

Great. Good luck. Remember you can always err on the side of overfilling the transmission a bit. And when you do the level check at the end it will correct it self and drain out the standpipe.

[@fondupot]

If your truck is a 2016 it has a 6 speed. Not an 8 speed. It’s a similar process but not identical and it uses a different fluid.

This is one of the best videos I have watched in a long time. I'm planning on doing this on my husband's 2016 Z71 Colorado this Sunday. Very generous of you to share the docs also, triple thanks for that. I am replacing the fluid with the original Delco since that's what it came with from the factory. I had a bad experience when a mechanic decided to put some off brand fluid on my Escalade when I asked him to do a fluid change and the truck never ran right after that. Needless to say I will never go back there again!! I would suggest to anyone doing this, that if you are going to change fluids use exactly the same that has been in there rather than mix brands. I'm going to see if you've done a spark plug change too. Our truck has right about 70,000 miles.

[@fondupot]

Thanks for the kind words. Just so you are aware, your 2016 will have a 6 speed transmission, not the 8 speed. The process is roughly the same, but there are specific differences. I would suggest watching a few videos that detail the 6 speed transmission fluid change before attempting so you have all the correct info. Good luck!

[@Cocora22]

@@fondupot thank you! I will look up a few more. I’ve seen several over the last few months and essentially the process is all the same, just have to be exact, no joke ruining a transmission. I’ve done all the other fluids several times on all our trucks, and the trans fluid on my son’s Xterra, just not on the Colorado, yet. 😌

[@fondupot]

Right on. Good luck!

[@eladiolagrimas2635]

Thanks for the video. It was very informative and helpful. I got a 2016 Canyon and I had problem with leaking transmission oil and I don’t know where it’s coming from. It started last night when I noticed a dripping something I thought it was just a water but when I checked this morning it was a transmission oil. So hopefully it just a loose plug . Anyway, thanks for the video. Stay safe .. keep vlogging . GOD Bless 🙏

[@fondupot]

Glad to help. Remember you can overfill on your initial fill up and then when you do your level check it will drain out whatever excess is needed. I would err on the side of putting too much vs. not enough. Because the trans will level itself out during the last step. Good luck!

[@jimh_vta]

Thanks for sharing. I’ve been wondering about this. I have a Colorado diesel with the 6 spd, but still good to conceptually see whats involved.

[@fondupot]

I think it’s a fairly similar process on the 6 speed. Should help you out at least conceptually. Thanks for watching!

[@IOwnCalculus]

@@fondupot It is indeed the same basic process on the 2.8/6L50. You won't have to get the exhaust out of the way, but the seal for the filter has to be replaced separately - it's the type that presses into the transmission case instead of being captive to the filter like the 8-speed.

[@fondupot]

Cool thanks for posting!

[@xthebeastwithinx]

Done. You are the man! Thank you for this video!

[@fondupot]

Glad to help! Thanks for watching. How did yours go?

[@xthebeastwithinx]

It went well! I am pretty sure the previous owners were from the north (I am also in NC) so after almost busting a bolt I left the exhaust alone and lifted it up a bit higher. You can still drain and clean the pan with a bit of wiggling and patience.

[@xthebeastwithinx]

Maybe a lot of wiggling. :D

[@fondupot]

Haha right on. Glad it worked out for you!

[@VortexArcade]

Great video! I just got a 2023, and I have the supposedly fixed issue of the really hard first shift when the revised version of this transmission is cold. Just wanted to see how to check the level, stayed for the whole thing. Thanks!

[@fondupot]

The 2023 is a new version of the 8 speed, so it may not be the same, but it's probably pretty close. I think they call it an 8L80 now.

Super helpful. Thank you.

[@r0bv123]

Thanks for sharing! This is high on my to do list. I bought a new-to-me used 15 Chevy Colorado and have been watching your other videos which have been super useful. I noticed you had a Colorado then moved to a Canyon, so appreciate that all the vids and parts cover both! I might do the same and get a newer model at some point, but in the meantime all these how-to's are top notch. Other than the shift knob and I think the truck bed lights, what other upgrades did you do on your Colorado that you have also done on the Canyon? If there's one new thing I would like to see and if possible is a front camera DIY when parking or tackling difficult trails.

[@fondupot]

Hey Robert! Just so you know your 2015 Colorado will have the 6 speed transmission in it. The process is roughly the same, but there are bound to be differences that I did not cover in my video. I did have a Colorado, and it was totalled in a parking lot while my wife was at work by a tornado! So I found a low mileage Canyon to replace it. I have considered the front Camera but haven't been able to justify the cost of it. But maybe one day I will pony up the money for the expense. Thanks so much for watching! All the mods to my canyon are well documented on my channel, just scroll through the last 2 years or so of videos and it should give you an idea of what I've done to it.

[@r0bv123]

@@fondupot Thank you for the follow-up! Yes good to know mine is a 6-speed so got a general idea of what's required. Wow on the Colorado, talk about truly totaled! Excellent reason to upgrade. 👍 I've done the Pop&Lock and interior cabin LEDs, might do the Trifecta tune next after I get the trans fluid done. And yes the front camera looks expensive, so understandable on future project.

Thanks. I have a '22 Canyon. I will perform this at around 50k miles. Currently at 23,000. I'll probably also add 15 - 20 ounces of Shudder Fix Platinum as I've read nothing but good results from that product.

[@fondupot]

I’ve not read anything about the shudder fluid you mentioned. But I would be hesitant to add that to your trans, because I have read of adverse reactions with similar products. If you’re having legit shudder issues you should have your dealer diagnose them. Otherwise a fluid and filter swap should be sufficient.

[@whitenas]

Awesome video. Thanks... recommendation. Next time you pull the pan install a drain plug so you can simply drain it out next service. Cheers

[@fondupot]

Yea. I’ve seen others take the pan to a shop to weld in a drain plug. Maybe I’ll do that.

[@whitenas]

@fondupot did you notice any change in driveability good bad or same?

The instructions are similar to the 6 speed. The only difference I see is a metal gasket at the filter site. I’m sorry to hear gm overfilled your truck. That’s frustrating.

[@rondigler7]

Great video with clear speech and instructions. Im tackling this job on my 2019 colorado as we speak. When just changing the fluid and filter as opposed to a whole flush will it still take 6 qts with what's left in the transmission?

The full capacity of the trans is 12 quarts. But a pan drop will just get 6 quarts. Thanks for watching.

[@rondigler7]

Thanks

[@Black_thunder522]

Great video. I just got a 21 canyon at4 with 36k miles on it a couple weeks ago. Kinda regret it because of the transmission fluid changing that I am seeing now. Called the local shops and they said it would be good to take to a transmission specialist whenever I go to do it to prevent anything breaking dropping the cat being up north. New cat would be like 2k. Wish they didn't seal transmissions like this. Used to be able to just drain and fill them

[@fondupot]

Thanks for watching. It’s not too bad. You could do a pan fluid change without ever having to remove the pan. Just siphon the fluid out the fill tube and replace. Then use the leveling process.

[@GoutamDAS-ls1wb]

Thank you very much for this useful video! I plan to do this myself soon. How do you get the remainder of the fluid changed--do you drive another 2 X 1000 miles and repeat X 2? Or is it not necessary? Your fluid looked very good but I have nearly 55K miles on my 2018 Colorado

[@fondupot]

Yea you can do that. Then you’ll have about 80% fluid swapped. Or you can have a legit transmission shop to a full flush and pump in all. New fluid. I don’t think that’s really needed for normal usage, but if you tow a lot maybe a full flush is worth it.

[@LCSRacing]

Great video, thank you. My 2018 , never had a flush no symptoms, you feel any issue only doing pan fluid... i.e. not draining the converter and mixing the earlier flavor of ATF?

[@fondupot]

I’d say if you can get a full flush done do it. My truck had a flush done when it was new so my TC already had the newer fluid. Doing a pad drop is only going to replace about half the fluid.

[@snors6689]

Good video; Looks like the blue and the black label ATF fluid have same part number. So what is the difference other than the obvious different color labels 🤪?

They are different part numbers. Not sure the difference. I just know you want to use the blue label stuff. Link in description to where you can buy it. Thanks for watching

Lordy! I have the dreaded 8L45 "shudder" at 40K miles on my '18 Colorado. Been taking it in to the dealership since mile 0 for every routine maintenance, but I'm pretty sure they've never changed the tranny fluid. Just did my own brakes yesterday, so I guess this is next. Figures it would involve moving the exhaust, but what can you do? Thanks for the great walk-through!

[@fondupot]

So it might be worth having a trans shop do the service for you. Since this procedure only gets about half the fluid out. A trans shop can flush out all the old fluid and put in all new fluid. Good luck!

Great video ! First one I've ever seen done. I'm getting ready to tackle this same job in 3K miles. Was wondering if they ever flushed it before you bought it ?

Watching your channel gives me confidence to try new ideas on my truck! @fondupot I would appreciate your opinions about the “shudder” coming back after a few years… I have a 2018 Canyon. Did the required transmission flush when I bought it in Dec. 2020 with 13K miles on it. Cured the shudder right away….

[@fondupot]

Id start with another fluid and filter service. If it keeps happening it’s possible your torque converter is “glazed” and needs to be replaced.

Thank you for taking time to reply! 👍🏼will do!

[@Peanutbutterjelly00]

Mine is a 2019 colorado with the original acdelco fluid and never had transmission problems. Dealer refused to do the flush with the mobil1 fluid since my truck doesn't have any symptoms and doesn't have any recall or service bulletin related to my vin number. I wonder if I can use the mobil1 even though it's only replacing 1/3 of the total capacity.

[@fondupot]

They’re supposed to change the fluid regardless of “symptoms”. I’d find a new dealer and get the flush done for free. Insist on it.

[@grahamfacer8042]

For what it's worth you can do this without removing the exhaust. It's more of a pain but you can unbolt the pan and slide it forward and tip it down. It rests on the exhaust and the transmission. Make sure you have your fluid tray ready to catch the fluid the pump missed (I forgot that part, very messy). Once tilted you can carefully grab the filter and even get to the magnets and wipe the pan. It's not as clean but it worked. It looks like it should slide all the way out but it doesn't due to internal bits of the transmission.

[@fondupot]

Yea. It’s definitely messier if you aren’t able to unbolt the exhaust. But it can be done.

[@SimpleGunner]

[@gtileo]

if i remember there from other videos on a Camaro, there should be a slight drizzle coming out when checking the level

[@fondupot]

Yes. Correct it’s ok to overfill the trans and then when you check the level at operating temperature, the extra will come out.

[@gtileo]

I'm curious if your trans being over filled was due to the TSB flush or it's possible some of the fluid from the torque converter drained out while the truck sat. Either way i might have to do a fluid and filter change on mine after about 30000 km of having the dealer flush mine. I'm getting some unhappy shifting. The trans seems to upshift too quickly and then has to down shift, also tends to hold gears too long before shifts, as well as it started over revving between gear changes for the first few shifts after initial startup and drive Starting to worry my trans is failing at about 117000km or around 75k miles

Maurice, sorry to hear about your health issues. This is quite a project. I've never done a AC compressor and condenser myself, but I think it requires several specialized tools and pieces of equipment. And you'd be exposed to the freon coolant that requires a special machine to capture and recharge.

Then dropping in 6 qts are Mobil 1 blue label? Maybe you could clarify as I plan on doing this Ina week or so. Hopefully i explained that well enough thank you

[@fondupot]

This is not a full flush per the TSB. The TSB flushes like 20 quarts of fresh fluid through the trans. It also gets all the fluid from the cooler, torque converter and pan. This gets nearly 100% of the old problematic fluid out of the trans. This video is a simple pan and filter fluid swap. It gets about half the fluid out of the trans. But my truck has already the flush, so this is just a preventative maintenance. I’ll do this on my trans every 25k-30k miles. I would not put anything other than the recommended fluid in the trans. But you can do 6 quarts of the blue label. And then a week later to another 6 quarts and you should have a good amount of fresh fluid in the trans. Definitely swap in a fresh filter too while your in there. Good luck.

I actually ended up adding another quart and a half the next day. And did the warm up procedure. Then as our 3/4 of a quart drained out. Been running fine since then. If you have the shudder total fluid swap is best. Mine had that done before I took ownership. Brown

[@sproulman1]

If shudder continues after fluid change you need a Torgue Convertor ...

[@tedmusic2638]

What type shift Handel are u using..

[@fondupot]

It’s a shifter from a Buick Envision. Bolts right in. Check my channel for a how to video, I have two.

[@tavensadventures3498]

Do you have to use a pump to drain out the transmission fluid? Doesn’t it drain out when you remove the pan?

[@fondupot]

Yes but that makes a bigger mess.

[@Spkrfrk1]

Ive had the dealer do my trans oil change every 30k since i bought the truck new. 2018 colorado v6. I've never had any issues with the trans and im about to hit 100k.

[@fondupot]

That's good. I recommend the maintenance interval you are using of 30k miles for the transmission fluid. Thanks for watching.

[@Spkrfrk1]

@Fondupot's Garage definitely appreciate all your videos. Keep up the great vids.

[@fondupot]

Thanks a lot @Alex!

[@brandonroberts9717]

Do you think it would have taken a lot more time to get the pretty fair amount left in the bottom of the pan just using the pump?

[@fondupot]

I don’t think it would be too bad. I took the pan all the way off so I could change oh that filter too. But you could always just do a fluid swap with 4-5 qts.

[@brandonroberts9717]

@@fondupot thx for your reply and the video! hoping I can get as much out as possible since I’ll be leaving some in the TC

[@fondupot]

Yea there will always be some in the TC unless you pump it out.

[@jasun6859]

Your the best

[@brentphillips2548]

There a company that makes a dip stick that can be slide into fill plug

[@fondupot]

Not that I know of.

[@AngelLovesToLook]

I just saw the link to the procedure, where did this info come from? Just curious.

[@fondupot]

I have a subscription to an online service manual. It’s from AllData.com. It kind of like a Haynes Service Manual. Only it’s all online. But everything can be printed off. It was like $60 for a year subscription. Pretty handy.

[@AngelLovesToLook]

@Fondupot's Garage I've used alldata few years back. How's the truck running after the change.

[@fondupot]

Runs great! Smooth and silky.

[@AngelLovesToLook]

@Fondupot's Garage that's great, I know the dealer charges a lot. I'm going to need this service soon. I'm 43k and it's time to get this done. Thinking of doing it my self. It is a simple process. Thank for sharing the info from Alldata.

[@fondupot]

You bet. Glad to help! Good luck

[@AbeVicious]

So, I'm asking around about the fluid. I've had 2 different answers. I've been told my colorado uses Dexron 6 T/m fluid, and yours is the LV HP fluid. I'm just trying to source the right stuff. Local auto parts do not carry the HP stuff, and i guess it depends if the pan is held by 15 or 18 bolts and if its 6 speed or 8 speed😑

[@fondupot]

6 speed uses the regular Dexron. 8 speed uses the Mobil LVHP.

[@AbeVicious]

​@fondupot what'd you do to take out the fluid from the torque converter?

[@fondupot]

@AbeVicious I didn’t. I only drained the pan. You need a special pump to get the fluid out of the converter.

[@billybritt5334]

Flush on that trans is the easiest flush you can do

[@st7oq2]

I am a 2020 Chevy Colorado 8L45 user in Korea. I finished the mission leveling at 40 degrees Celsius, and there is a shock at low speed. Should I finish the leveling temperature at 45 degrees Celsius?

[@fondupot]

The procedure for level check is at 95-113 degrees F. So whatever the equivalent to that is in Centigrade you should do.

[@st7oq2]

​@@fondupotYou want me to finish the leveling at 113 degrees F?

[@st7oq2]

​@@fondupotI'm sorry. I'm using a translator because my English is not good.

[@fondupot]

It’s a range from 95-113F. So you can check it at any temp in between.

[@st7oq2]

​@@fondupotthanks

[@mustang8258]

Who makes this trans? Is this in house GM?

[@fondupot]

Yes.

[@shiftmotorsports9803]

I made the mistake of taking mine to the dealer to do a tranny flush and filter change along with an oil change. $750 total. They said it needed a total of 21 quarts of tranny fluid. Never again.

[@fondupot]

Well if they did a flush it makes sense that they use extra fluid, cuz they will pump it Thru the trans until they’re sure it’s all clean new fluid. But 21 quarts still seems excessive. My goal is to do trans pan fluid and filter every 25000 miles. 6-7 quarts every 25000 miles is only about $60-70. And a filter is only $18. That will keep enough fresh fluid in there to keep the trans running good for a long time.

[@shiftmotorsports9803]

@@fondupot Mine has 77K on it and I have had it flushed twice but this is the first time I had the filter changed. I requested a drain and fill but when I picked it up, they said they only did flushes. Next time I will do what you did. Owner's manual says the filter needs changed every 45K in severe conditions. Thanks for the video!

[@fondupot]

@@shiftmotorsports9803 Sounds good! Thanks for watching!

[@Spkrfrk1]

I think most ive paid was $250

[@billsite34]

Might not have been overfilled. There is a lot of "drain down" if it has been sitting for a while.

[@fondupot]

It had just been driven earlier in the day.

[@drewgalbreath5654]

Agreed. If the truck was off and the trans was cold, it was probably just all sitting in the pan. Probably wouldn't have come out at least as bad if it were running

[@user-kk4xg7fb7h]

​@drewgalbreath5654 that's exactly correct, Trans pump is pumping fluid while the engine running.

[@BBSAXX]

Chevys way of saying you touch you void all warranties.

[@XjDrZ]

I thought the temp needed to be at 131-149 degrees?

[@fondupot]

I think that’s only for the Sports cars with the 8 speed. I got my information from directly from the service manual.

[@XjDrZ]

@@fondupot I saw you comment on the forums and it had another transmission info on the 6l, 8l, and 10l bother 45s and 90s and I remember him saying on all 8l45/90s temp was 131 to 149 amd even on that same forum there was another guy that checked his at 143. I'm trying to find where it's located in my manual

[@fondupot]

​ @RedBeard109 this is what the service manual says, exactly: -CTS-V/LT1 Camaro, if running a track session, should have the transmission fluid level checked when the TFT is between 55-65°C (131-149°F). 8L45 for Canyon/Colorado is 95-113°F. 6L50 for Canyon/Colorado 86-122°F I don't know what the 10 speeds are, because Canyon/Colorado doesn't have those, and my service manual does not list them.

[@XjDrZ]

@@fondupot thanks a lot man for getting this for me!

[@thejewcanoe1]

You might have forgotten to shift through each drive range on the transmission. P R N D M1 2 3 4 5 6 7 8 to make sure the fluid moves through the entire system

[@fondupot]

I shifted thru PRND, and that's all you need to do. Putting the transmission into M or L mode and then clicking each gear (1 thru 8) doesn't actually shift the transmission into those gears, it simply locks out those gears for towing purposes.

[@shaunram5327]

24k miles, damn thats a lot of material

[@fondupot]

Nah. It’s fine. I expected some wear materials to be on the magnets. It was all very fine and no big chunks. I’m not worried about it.

[@shaunram5327]

@@fondupot wouldn’t want it in my ride

[@fondupot]

I guarantee yours looks the same. 👍🏼

[@Resistculturaldecline]

@@shaunram5327 That wear material probably deposited into the pan & magnets in the first 1500 miles during initial wear-in. It probably won't have as much on the second fluid/filter service. Some well respected transmission shops will do a fluid change around 3000 miles after rebuild. That's when the bulk of the parts have worn-in. No reason to let the trans wallow in its dirty bathwater after that. Trans service at 3000ish miles, then @ 50k and every 50k after that. Those type service intervals will make a trans last 2x long as most people consider a usual auto-trans service life.

[@shaunram5327]

Still a lot of material, regardless how smart you think you are

Also, great video, I used this to change the transmission fluid temperature sensor wiring harness. (GM 24046895) for anyone that has this issue.
