2015 Subaru WRX Ep. 649: Transmission and Front Differential Oil Change

[@shamwaymoonyos9578]

The vacuum intermission while the fluid drained was enjoyable :) Love this channel. Saves our asses when trying to install IAG Aos

[@GR8GUY54]

I did it! The front and rear was SUPER easy! cherry! I even had to use your jack trick for the rear...man! that sucker was in tight! Just learning here and buying new tools as I need them. If I had to do this all over again, I would like to have a smaller torque wrench and breaker bar. They come in handy but I managed with my big ones. now I know what gift to by myself in the future. Thank you! 2015 WRX complete!

Just did this today, thanks for the video. So satisfying being able to do this myself.

[@LastHumansGarage]

congrats brohemian

[@Kradle]

Just wanted to say your trick with the jack on the differential bolt was a life saver for me; A combination of awkward positioning and probably an overtightened bolt meant I had to use my jack to loosen it also...It was a bit sketchy, I kept picturing the breaker bar breaking loose onto my face...but it worked lol. Thanks

[@LastHumansGarage]

no problem broseph

[@jpd3070]

Thank you for saying at the top of the video that the transfer case/front diff are the same... been driving me crazy.

[@LastHumansGarage]

cool

[@futix13]

My man, this is exactly what I needed. Great attention to detail and thanks for saving me cash

[@LastHumansGarage]

Glad I could help!

[@noahowen5061]

I think the subs want another lasthumangarage home life dance party!! Those are so amazing!!

[@LastHumansGarage]

i been thinking about making one, just havent had the energy yet. and i think you are one of the very few that are asking for that...

[@kirkniese]

I appreciate you consolidating your oil after you're done. Nice work! Enjoy the car! About to change my Forester's MT fluid and rear diff. oil.....and hopefully by this time next year, I'll be changing out the same on a 2018 WRX. Thanks again!

[@garthhh]

I felt anxious for you right before all that oil dumped out.

[@Dave-so7sf]

Thanks man, I've been trying to figure how to access the fill without pumping it. I had Subaru change my front and rear fluid at 30,000 it was cheap money. Ever since that I've had an issue with very hard shifting when the fluid is cold for the first 10min. The ambient temperature can be 20 or 65 Fahrenheit doesn't matter. Kinda sucks when trying to downshift. I'm going to try to change it with redline 75-90 NS hopefully it works.

[@LastHumansGarage]

I always have that for 5-10 mins when it's maybe 40f or colder

[@PittiesAndMore]

When you purchase your next home you should plan for a car lift in your garage. 😃

[@LastHumansGarage]

who knows.

[@KingFrenchy11]

Did you ever get or heard of the front differential fluid leaking when swapping the coilovers on either side of the axles? When I changed my driver side after putting everything back together on my passenger side, the middle of the car where the transmission sits starting leaking.... did I pop something out of place?

[@LastHumansGarage]

i mean did you take out axles? i cant remember what it looks like.

[@okthen8445]

Hey I have a 17 sti. I've changed transmission oil before many times but never on a manual car. It's not much different besides there isn't a pipe running through the top of engine for filling. Anyways I was wondering if the drain plug and fill hole/dip stick holes are in the same place on my car; in fact I'm not sure my sti has a MT dip stick. Can you clarify? And also the front diff is also just the transmission right? Got confused didn't know there was a front diff

[@josephhernandez4757]

Did you ever find an answer to your questions? Im wondering the same thing lol

[@shawncey2424]

Running flex the exhaust tips stay cleaner for longer. I have noticed.

[@LastHumansGarage]

dood my tips never get black.. after weeks of driving.. never..

[@boslet2]

I wonder how often you should do this? According to subaru (manual) is never recommends to change, it just says to inspect every 60,000.

[@LastHumansGarage]

most people never do.

[@zackstaa7826]

By 60k, your power train warranty is done. If you go much longer than that without changing it, say past 100k, I definitely wouldn’t change it. New oil can cause seals and gaskets to leak because it will clean the debris that’s likely holding the oil in. You’d have to take apart and reseal the transmission. Better to change every 30k, that way the rubber seals stay lubricated and debris free, transmission will last longer.

[@shawncey2424]

The first transmission fluid front diff I did with you Subaru OEM fluids I was thinking about doing Amsoil severe gear oil for the front transmission and rear diff. Or should I do an oil sink mass for the transmission and front diff. What do you recommend I'm on flex-fuel about 350 wheel horsepower

[@LastHumansGarage]

i would do the severe as long as its the proper type

[@jessel1217]

Motul Gear 300. Nothing else imo.

[@estefunky]

Hi friend, can i ask you, if this procedure is the same for the Subaru Impreza 2015? Thanks!

[@LastHumansGarage]

i would guess so, but different engine..

[@briangilbert12]

I see you removed the engine cover, where did you get the intercooler cover to make a nice seal with the hood?

[@LastHumansGarage]

the shrouds come w the grimmspeed tmic.

[@briangilbert12]

@@LastHumansGarage awesome good to know thanks man, what kind of power are you putting out? How big were the benefits going with the bigger intercooler? I'm debating on getting one as i plan on modding this spring

[@javiermichel4618]

I’m new to Subaru and was wondering if by changing out the front diff fluid is that also changing out the transmission fluid?

[@LastHumansGarage]

hmm yes. as the front diff is integrated with the trans.

[@javiermichel4618]

LastHumansGarage great thank you 🙏

[@CaptainSnagglez]

Great video man, very informative. Thanks for posting

[@LastHumansGarage]

Thanks Big O.

[@JustDisney]

What type of fluid are you using for the CVT? Can't find any to purchase. 2015 Subaru WRX CVT state 2

[@LastHumansGarage]

i think they use ATF.. been a while since i messed w that..

[@meorge9359]

You've probably mentioned this previously. But why do all this maintenance (not that it's a bad thing) to a lease?

[@LastHumansGarage]

dunno

[@GR8GUY54]

George Marris because he likes to learn new things and teach us at the same time. he's good at this.

[@Eddy61362]

Can you change out the center diff on the base wrx 6 speed ?

[@LastHumansGarage]

hmm dunno.

[@dnawrapsatl]

Quick question. Can I just reuse that gasket for the 1st time?

[@LastHumansGarage]

i usually do

[@TWRX_Chuck]

Gear oil smells so dang bad.

[@LastHumansGarage]

not as bad as my bowel movements..

[@dionegz40]

Thanks for this video. Will get this done with your video. WRX 2015

[@LastHumansGarage]

sweet

[@ChristianWowk]

What was your mileage when you changed it? It says in manual for 2017 to inspect every 30,000 miles but at no point does it indicate to perform.

[@LastHumansGarage]

ah 15k maybe? it would prob be fine for 60k miles.. but most people here like to keep their car nice and fresh.

[@XTIMMEHHHX]

did you amazon the fluid or dealership and cost if you remember?

[@LastHumansGarage]

i bought at dealership parts counter. in fact, im buying more today. around $10-$11 each.

[@kiddcisco]

Was your oil the Extra S version, p/n SOA427V1700 or just the regular HPGO

[@johnmpifer]

The Cisco Kidd They don’t Brand it “Extra S” anymore. Just “Subaru High Performance” gear oil.

[@MrNiceGuyGTL]

Do we need 7 quarts to change the whole transmission? Front/ rear diffs and trans?

[@LastHumansGarage]

whatever the video showed. i had more than 1 video on these changes.

[@marcn1777]

Would autozone take used gear/transmission oil? If not where would you recycle it?

[@LastHumansGarage]

my dump site takes it

[@codydakota95]

Auto Zone accepts gear oil, or anything petroleum based lube for that matter (or synthetic equivalent). They don’t take antifreeze or gasoline/diesel.

[@SambSylla]

Do you know where I can find the front diff fill on Subaru Ouback 2018?

[@LastHumansGarage]

naw, never had an outback

[@SambSylla]

I got it. The front diff refill plug is in the same location like in your WRX. I will take this opportunity to thank you very much for all the trouble you go through so the rest of us can avoid dealer's ridiculous high cost. Your videos are instructive, informative, easy to understand and very clear.

[@caritaxd]

Hi man.... in wrx 15" CVT is the same process?? just put CVT oil or High Torque Oil and that's it?

[@billy220985]

Waiting to find out

[@paulverstraete9157]

@@billy220985 leave the cvt alone....has separate diff fluid use gl5 just like the rear....I use the Subaru fluid he uses the fill is a pull out thingy in the same place as the manual dipstick its afor the vent for the diff......find a video for a forester xt its the same......

[@GeekyMitch]

So stupid question - maintenance manual says to change brake/clutch oil at 30k miles (I just passed 31k on my 2016 wrx) - is this what that is referencing? A little new to DIY on a car, so just want to make sure I'm not forgetting to do anything important!

[@redding4540]

Mitch Brenner every 2 years...it doesn't matter on your mileage. the brake fluid is not pure because of all the minerals added to it.

[@thomasblomberg1151]

I love your videos man. You have been a ton of help.

[@LastHumansGarage]

thanks bro-berg

[@GR8GUY54]

So I'm at 36k and no longer under warranty. the dealer said my warranty plan did not call for this at the 30k maintenance and instead just got another oil change. is this something I should consider now or in the future?

[@LastHumansGarage]

prob true. the oil lasts a long time.

[@GR8GUY54]

LastHumansGarage just purchased all my tools for this and will get the oil on Friday. Wow! It will be 40K by the time I drain the fluids. Will be doing both front and rear. Thanks!

[@cobra454tim]

my 3.6 r diff filler is so easy to get to because I have no intercooler in the way.

[@LastHumansGarage]

i test drove a 3.6R outback once. before we bought the forester.

[@richardclark3758]

I added 3.5 quarts and I was way over the fill line; like a 1/4".

[@LastHumansGarage]

hmm

[@CEPHALEXIN323]

Richard Clark same here I was over

[@leosfo]

Yep. just did mine today, let it drain 4 ever, 3.5 qts was high.

[@ThePikmin18]

I accidentally put 4 in, drive like 70 miles on a trip and realized what I did so I drained some out. I’m so dumb.

[@alimusan84tt]

Changed mine today. I've put 3 quarts and checked the dipstick it was above the "F" line.

[@ThePikmin18]

So wait, the transmission fluid that was changed is the front diff?

[@LastHumansGarage]

on that car, yes.

[@ThePikmin18]

LastHumansGarage thanks man I appreciate it

[@BottomOutGarage]

So front diff and transmission are together correct?

[@LastHumansGarage]

correct

[@rich__details]

So the 3.5 qts you pour in is combined with the front diff and transmission fluid correct ?

[@georgeemanson]

I have had a Subaru forester 1997 (automatic) from new, that has been great for all the years with very little to do other than annual services. However, recently I have had a lot of vibration & shuddering on the wheels when making tight turns (left or right). It is difficult to identify which wheels the noise or shudder comes from and I don't feel much through the steering wheel. I have had all difs replace that has reduced the frequency but not always. We hope it isn't the automatic gear box but has anyone got any ideas what to do next.

[@LastHumansGarage]

the only thing left really is those CV axles...

[@georgeemanson]

@@LastHumansGarage Thanks, it is good to hear from someone else on their thoughts. I will check out your idea. Thanks again. We don't want to loose our car..... she is part of the family.....we have had her more than 21 years and has been a faithful work-horse.

[@LastHumansGarage]

@@georgeemanson if the CV joints arent worn, then the tranny is def done if its over 20 years old.. but wheel shuddering is more like front wheel bearings..

[@georgeemanson]

@@LastHumansGarage OK I have a look at the front wheel bearings....... the car has only done about 70,000 miles over the years..... so well within a Subaru's capacity... Thanks

[@LastHumansGarage]

@@georgeemanson easy to check. jack up a front tire off the ground. grab each side of the tire and wiggle back and forth. there should be no movement.

[@miller6610]

Do you have the Michelin x-ice tires?

how much are you selling the radio for?

[@LastHumansGarage]

ah $50 shipped in usa only.

[@raiden000]

im no expert but 1 hp= 745 watts so thats 3725 watts, so unless that is plugged into your electric oven's plug that is not 5hp. most garages are wired up to a 20 amp circuit, thats 2200 watts maximum.

[@LastHumansGarage]

technical stuff!

[@paulverstraete9157]

lots of garages hit the plug on the opener circuit and lights.....typically underwired...….

Anything different for the STI?
