Hey man, I have 2007 Trailblazer with the same problem. My reverse gear stop working this morning when I came back from my sister’s house. Check with the workshop and they said $2000 for rebuild. I live in Tucker and saw your video. Assuming you live in Georgia. I am hoping to save some money if this one is cheaper. Can you please let me know if you can help? Thanks!

[@HotRodDave]

@@houseofstz1440 What Engine and Transmission is in it?

[@ffemtx4]

For all of those asking (AND to help Dave out, if I may)... I know he worked on a 4L80e but alot of you are asking about the 4L60 or 4L60e. The 4L60 is the same tranny as the 700R4. The 4L60e is the same tranny also except it's electronically controlled (hence, the "e") instead of Throttle Valve (TV) cable controlled. However, they all may have a different length pin. They were "length specific" from the factory. That's why Dave KEEPS mentioning that you MUST measure the amount of travel. Replace it with a shorter one, or the same length, and you will have wasted your time. Too long and the reverse band will drag or stay engaged and it won't shift into forward gears correctly or harshly. Or possibly lock up your tires going into 2nd gear. Great video, Dave!

[@HotRodDave]

Thank you and thanks for the information. I am not a transmission expert but have repaired a few over the years.

im in charlotte nc can you help me fix my reverse ?

[@petes2197]

Great video! Bought kit for no reverse in 1999 gmc Sierra 2500hd. I did have a metal hose over my wiring harness that was connected to one 10mm bolt and then went up into another hole. Also kept 6- 8mm bolts for pressure switch separate and needed to take off as they go through valve body. It fell out but used some brake clean on it and put back in during reassembly. Also took out most of valve body bolts except 4 corners and loosened about as far as they would go. This way I was able to take out servo and put in without lowering valve body. Also the transmission filter has a seal on it and I couldn't get it out so took seal off new one and shoved it up there. If it is even called a valve body? I went into O'Reilly to buy fluid and was laughing. I asked how many quarts I needed and he said, "Are you taking out the torque converter?". I said, " Dude I don't know what that is but I'm deep into the transmission and don't know what I am doing." Why? Because I watched this video as well as a couple other transmission teardown and was doing it under the truck after taking a transmission bath. Truck works! Has reverse! Cost $100 with fluid, filter, brake clean, and servo kit. Thanks dude you rock! Blessings to you and others reading this. You can do it! Have faith!

Thanks for sharing this repair. I'll be doing the exact procedure in my driveway on a project truck I bought. Drained the transmission yesterday and found two of the reverse servo bolts undone. I suspect someone was in there, so I'll have to check on the condition of this servo and the proper length of the pin. Your video really helps to get my head around this. Should be simple enough to check and fix as needed.

[@Abu7929]

Thanks for video buddy. I extended mine to 4.98 or so, fixed reverse, but did some crazy stuff in forward gears, engaging transbrake turned out. Servo pin miles too long. Didn't realise there were different lengths. Cut it down to around 4.4 or so and everything works a treat now

[@strattuner]

built transmissions for 47 years,you got guts,and if you are a guy who pays attention to detail,you can build them,trick is stacking the components as they come out,also taking the wobble out of everything is the secret to longevity,you have repaired the trans back to design,changing fluid at regular intervals is everything,bushings,seals and new clutches and bands solves 98% of the failures,but the damn fluid and filter is the key to lasting,change fluids every 45k no matter what,hang in there you got what it takes,it takes guts

[@HotRodDave]

Thank you. I appreciate that. I plan on buying and building a 4l80 for a hot Rod project soon.

@@HotRodDave yeah you can do it,take everything out and stack it,and go to trans parts vendor and tell them you want a pictorial of it,it will show all the stack components and how they assemble,when doing valve body take all solenoids and put them in order they come out,clean one valve at a time,no sandpaper,i use scuff pads the body shop boys use,clean it all clean enough to eat out of it,then there's so second guessing,yeah you can do it,if you can build this unit you can build about 200 others,then your bottom line in your shop,will amaze you,this will require more help,r&r is almost as important as building on the table,good luck,you won't need it,you are scoped in to detail,you'll do fine

[@StealthyWolfDaddyWerewolf]

I blew my reverse while stuck in yard. I used the moment to do a good durability test and it did what I expected. Luckily I have parts for and off a 400. So, I noticed you were fighting those seals. Then I realized my reverse bang before blown might have been the seals not being flat teflon like my spare 400 servo. I remember when I built my 400 that I had some thing where I chose the teflon I had because they didnt stick like that. On 4l60's I always use pinless accumulators because the pinned stick and do weird things. I plan on rebuilding / going through my 95 4l80, but I removed / cleaned / inspected the valve body to see if it caused the issue. Plate was worn a little but someone did sonnax reverse parts .etc. So now I am going to put this little extendo pin I have been saving in and do the same for research. My other thing before this happened was a delayed reverse, so I think the rubber seals might have caused sticking with clutch debris and shaved my band. I overheated mine during the "test" , but I suspect From examining my servo parts it stretched the cup, flared the metal pin tip and whatever else from seizing and slamming. Also not sure if my forward to reverse had some accidental slam damage, but I was curious if there is some kind of part / failure that happens to blow reverse like this. I am more along the lines of a seizing reverse servo assembly doing a hydraulic ram to the reverse band forward and backward from rubber seals.

[@HotRodDave]

I am not a transmission expert but the band can break causing no reverse. Lots of parts in there that can cause it but the short rod is the most common that I know of

[@StealthyWolfDaddyWerewolf]

@@HotRodDave I got mine to kick in reverse yesterday after hours of trying to use the extension piece, grinding it to a nub, then realizing I had to weld the rod to make it .9 longer. It worked for a little while, had to lift it off the ground to make something start working, tires roll, then it just gave out. So I now have no reverse and no 3rd but it was probably a issue anyways since I discovered the fluid was toast and everything is probably not happy. I am still thinking something to do with the servo pin and other stuff / pins not engaging probably because of no viscosity in the fluid. Oddly I don't have good fluid pressure in reverse, a little more at 2k but I will soon find out once I get it torn down. This is my first 4l80, but I do kinda like the basic design similar to the 4l60 and th400. Only thing I don't like is if I don't know it like the back of my hand, I am afraid of driving it. It's expensive for the rebuild parts, but I guess it's the price you gotta pay if you want something simple, heavy duty and reliable when maintained. I fear newer vehicles with too many configurations for parts. So it will nice to see and have a heavy duty transmission like the 400 but with overdrive. I have been trying to do all my research on it this month and thankfully it doesn't look horrible to deal with.

@@anthonyflorence4389 some people just weld a little on top of the rod pin or whatever the correct term for it is. The kit I got from ebay just hammered down on top of it. In my case it was the correct length but you really need to do your homework and make sure you measure correctly. Someone in the comments made mention that there is an adjustable servo or something now. I don't know anything about that piece but it may be a good thing. When I was doing research on the topic I read that there was 3 different size rods from the Factory and often the put a short one in . That being said would cause the band to not engage prematurely in some transmissions after some wear. That's why adding some length to the rod applies the band and reverse will work again. In some cases the band can break and then you have a bigger job on your hands.

@@mistersniffer6838 I don't have a problem with it. You know you can look up where they go. I use trans gel to keep them in position. This truck is still working fine 🙂

@@HotRodDave - You said you dropped it an inch, not take it off. If I knew you took it off, duh, accessible check balls. Okay, well, I guess your way is a hidden secret, so, I will tap out here, later.

Hey what is that let called where u get it

[@HotRodDave]

What's a let ?

[@luisvelazquez4650]

Good afternoon very good video thanks for your información. Sorry this part number ( GM th-400/4L80E) fits a 2002 chevy tahoe with a5.3 4x4 engine thank you

[@HotRodDave]

A 2002 Tahoe with a 5.3 probably has a 4l60 transmission. I don't know if it is the same. You would probably need to Google no reverse repair kit for a 4l60

[@luisvelazquez4650]

Thanks you

[@leonardleonardlove20]

M & M Transmissions now sells an adjustable servo makes it a lot easier.

[@HotRodDave]

That cool

[@paigeclenney1871]

$500 😂😅 this kit he used is like $50

[@andrewbeetle7301]

Would it work for a 03 3500 lost reverse

[@HotRodDave]

It should be the same transmission. 4l80 it is a common problem but you will need to do your homework

[@cluek9780]

What is that part # you got on eBay? Seals #? Thx

[@leebarnes655]

Fitzall T34913 on eBay for $18.50 free shipping. Some offers come with Orings and gaskets and of course cost a bit more. Fitzall of course also sells them and for the other transmissions other than TH400 and 4L80E.

[@reelingwithalik7499]

How much should it cost for a shop to put the extension on with transmission in?

[@HotRodDave]

Depends on your area. I would charge $500+parts Most shops will not do it and say you need a total rebuild. That may be true in some cases.

[@sparkynm156]

Most trany shops will say you need a full rebuild even if you were just low on fluid or a bird flew in the shop...

A piece of PVC pipe and anything flat there handy will do wonders for putting that piston back in place

[@pjdn]

Fyi...I just think it's really sad that you couldn't actually back it out off the rack so we could see it moving in reverse for more than about a foot at most. I watched the entire video waiting for that moment that never came. Then when you were in the driveway I thought you would get in the truck and put it in reverse but it just didn't happen.

[@HotRodDave]

Sorry Dude I guess I didn't think about it. I was just happy it worked and is still working. Thanks for watch and sorry to let you down

[@Nodeagent]

Hey Dave I have the same exact problem. I heard you mention your friend lives in Georgia and this is probably a long shot but can I pay you to replace mine if I bring all the parts?

[@HotRodDave]

Thanks for watching but I am not taking in any work at the moment. I have my hands full finishing some projects that will take up my shop time well into the fall.

[@Nodeagent]

@@HotRodDave no worries. Has the repair held up?

[@HotRodDave]

@@Nodeagent yes it is still working

[@Nodeagent]

@@HotRodDave you’re the man Dave. following your video, and the important details you covered, I was able to restore the reverse gear to my truck this morning!

[@HotRodDave]

@Nodedev That's awesome. Congrats on the repair. That's a challenge not many will try.

[@dogwithinternet38]

Hello, I have just done this on my 4L80e and now I have all forward including reverse and the neutral, park still works, thinking maybe the pin is now too long?

[@HotRodDave]

Not sure what your problem is. Sounds like everything is working.

[@b.s.adventures9421]

I’m looking at buying a 2000 Silverado 2500 for cheap with no reverse. Hoping it’s this issue..🫰🏻

[@HotRodDave]

That would be a cheap fix. I wouldn't mind stumbling onto a cheap 3/4 or 1 ton.

[@davidoberstar6740]

Was this for no reverse at all? Mine seems to slip some before it catches and does better when cold versus warm.

[@HotRodDave]

When he brought it to me it had no reverse. You may have the same issue but not as extreme yet.
