I just did mine I got the corvette servo/long pin kit for my 2008 suburban and it's like a new transmission. I had a terrible double shift when going to 2nd and now nice and firm quick shift😊
Thank you so much praise God for people like you. You save me so much money and so much time. I rebuild a transmission for a 2001 F150 One Time by watching RU-vid. God bless you guys and I really appreciate the hard work that you put forth in the time that it takes through these videos
My escalade with 195,000 miles had a 2 to 3 shift that was slipping everytime and could not grab the gear. I was worried I would need an expensive transmission rebuild. I put in the corvette servo and it completely solved the problem. It was a bit of a headache to get the snap ring back on. A tip if you have that issue, tap the cap in lightly with a hammer. Im at about 500 miles on the new servo. Im crossing my fingers the slipping issue is solved for a good amount of time to come.
@@kylel4689 The fix turned out to be a "band aid" in my case. It lasted for maybe 2,000 miles then the transmission could not shift into 3rd or 4th gear at all. I hoped I would get a little more out of it than that. I wound up getting the transmission completely rebuilt. I have about 6 ,000 - 7,0000 miles on that rebuild and it is still running perfectly fine, no issues, but it of course came with the cost of a rebuild.
@@marleyjoyner2097 Sorry I didn't see you question until now Marley. See my reply below if you're still considering doing this. In my case it just was a band aid fix.
Thanks for the demonstration. Doing this in a Trailblazer and there's not enough room so I did have to lower the transmission...Would love to know how you (or some tip) replaced the final snap ring to finish this.
Thanks! 05 Escalade with 145K shifts so much better. My part cost $40 and I had to disassemble piston/pin assembly in the car due to tighter clearance. Cutting the old blue o-ring and pulling it out was necessary to remove cap also. Great video.
Awesome video! I have a question. I have a 2004 Cadillac Escalade and it has 155xxx. It runs and drives fine but per my research I do hear that the transmissions in them tend to heat up and fry pretty quick. I don't do any hard shifts or anything but do you suggest changing (not flushing) the transmission fluid for safe keeping? I hear some mechanics say that they're ticking time bombs and others say changing the fluid and filter is better for it in the long run.
This really helped with the very loose shifting in my Suburban. It was cheap and only took a couple of hours to replace. I had to break the blue O-ring to get the cap out as others mention. I just a long cross-state drive through the mountains and shifting was nice and crisp.
I am finishing a fresh rebuild on 02 tahoe 4x4 4l60E. Frictions and seals were good and it worked fine beforehand, yet had to do rear main seal after 240k miles finally and figured it was out, so freshen it up. Using Sonnax pinless accumulators, sunshell, boost valve, reman valve body etc. Replaced planetary, old rear had some play in pinions. Used Sonnax hardened backing and apply plates with 65E 7 friction set up. Instaling Sonnax 4th super hold servo and was contiplating on whether to use the corvette servo as not looking for harsh 1-2 shift in normal driving. Under acceleration or when towing, that's okay. Had a shift kit in my old A body, turbo 350, best second gear 'skirt' even at part throttle and loved it, yet this is family hauler too. Thoughts appreciated and thankful for internet as had to drive around to different shops and get to know them for info in old days.
I just received an 03 tahoe from sister. Learning tips and tricks. In the process now of changing transmission fluid/filter. It has 228K miles. After reading your post I wonder: Should I be looking at what you have been doing? Should I be making these same repairs? Odds are this Tahoe was not being kept up.
@@Hizenbird Depends on how much down time to can afford. If it's 4wd there's more involvement too. I took mine down for a year as not able so much these days. Plus what it takes for each day to keep up. Some of the things I did that were either maintenance or failed that also helped make it easier, where taking the intake off, resealing the lifter valley cover seeping, replaced knock sensors, both had corrosion front was worse, and new boot/harness as connectors fell apart. I replaced the cam sensor, oil pressure sensor while it was off along with new fuel injector orings, cleaned throttle body, new sensor for it as they can take out a trans like the old TV cables would do on the earlier 700s. Also, had several broken exhaust studs on manifolds. With the cat pipe out of the way anyhow, I removed the exhaust manifolds to repair/remove broken bolts, upgraded back with newer style 03 up bolts from GM. With intake and exhaust out of the way ( along with inner fender liners), it made my life easier to get to and ultimately reinstall the upper brackets/bolt/studs upon reassembly. Yeah, most will figure overkill, yet I've done a fair amount of restoration to it over the past few years and cleaned/waxed/derusted and painted back bolts, brackets, hidden areas. Also replaced split loom plastic tubing around main harnesses on drivers side due to exhaust heat and rewrapped with 3M black tape. Looks like factory. R & I'd valve covers, replace valve guide seals using rope method as has plenty of access and could see a bit of oil residue build up on the exhaust valves, etc. etc. Aside from that, I did a lot of reading and watching videos, combined with my years in automotive, although never built many transmissions, yet been around it, and took on the challenge. I'm glad I did as it drives like new again. Considering I saved up on parts over the last few years, rebuilt the front steering and suspension and complete brake system, all new GM mounts, new universal joints, etc. Rebuilding the 4L60E does take some patience and there are many area's that can make or break the build. I had to save up to gather parts, then when the job began I ended making many changes as I'd had more time in between to study and learn more. I went from a, "Put it back stock", mentality to a true purpose built unit that should withstand any towing and miles I could put on it, plus to pass along to my son. The newer vehicles today, all well and good for most folks, have too many controlled/connected functions and are getting overcomplicated IMO, neat as they may be, I chose to continue to invest in this one. Keeping all receipts in case some dummy totals it, Lord forbid please on that. Okay, so on the build I acquired the tools slowly as I progressed online from various venders. I also rebuilt my transfer case while out too, same thing. Transmission bench has a great video series, then there are so many others too. Sonnax has a great deal of technical information, there are a variety of mods that can be done, yet make sure they are done in conjunction with the build purpose. Mine's not a drag car nor will it be street raced, etc. Just for it to shift properly and be reliable especially if towing. I did build up a 2 - 4 servo setup with all new GM components, new pin, cover, 2 & 4 pistons, GM scarf rings, springs, etc. as concerned about having too harsh shift in second, especially like in slow/stop n go traffic. However, I also built up a spare 2 - 4 setup, all new parts including another new GM center pin, yet with a Corvette servo and super hold 4th servo and got it all together while transmission was still out and set up the apply clearance to within spec by properly grinding the pin to length with the correct radius by chucking it in a drill and using a disc grinder, carefully!. Now that I know that it works and how it shifts, I may put that set up in it when we go to tow a camper. If it makes 2nd shift like third does now, I'll be very happy as it's quick and firm under mild to heavy acceleration. Don't leave out the small things, TCC valve, boost valve, 3rd check ball capsule - mine looked okay and didn't leak, yet when I removed and compared it to new GM unit, the ball seat was wallered out and wouldn't have lasted too much longer without giving problems. Again, so much to put down and so many others who've actually done this for a living will have their say too. All I can say is for the cost of a reasonable custom build elsewhere, this thing is now up to 4l65/70 standards. Yes, that includes new old stock GM 5 pinion planetaries, not aftermarket or rebuilt stuff. All the Sonnax I could put into it, lol. Including one of their reman valve bodies. I used Rock Auto and many other venders by shopping for best prices to keep costs down and again saved up over the years in anticipation, glad to still get N.O.S components for this vehicle. I was very fortunate as prices have gone up a bit since I started collecting. All said and done, It's my personal vehicle, it's now back on the road and I have the personal pride of knowing that I did it and if anything ever comes up, I know how to check it out and how it operates. Hopefully that won't be anytime soon. Hope this helps others and any additions to this will only solidify the DIY of these transmission's and GMT 800's.
@@mu9627 Wow! That sounds like quite an experience. Over the last few days I just changed a bunch of fluids in my car that desperately needed attention. My rx300 (daily driver) has 285K miles. I changed Trans fluid and filter, engine oil and filter, Front Diff. fluid, Rear Diff. fluid, power steering fluid. It was quite a bit of work. My brothers sees this and comes out and says, "I hope there is some benefit to you doing all this work." I explain to him that I'm not just changing fluids. I extending the life of my car, I'm saving money, I'm building patience, perseverance, critical thinking skills, and creativity skills, not to mention more knowledge about the thing that I heavily rely on. Good on you for going through that process. I hope I'm able to do the same.
i put a 6.0 from an escalade into my brother's '92 silverado and while the engine is great and performs like a beast the transmission has been a letdown. it always seems to be caught between gears and slips when shifting. hopefully a corvette servo allows it to unlock its full potential
@@slow_restoration I have an 04 Suburban 1500. I was able to follow along and change out the servo. Although it shifts a little better, it’s still not trustworthy. I intend to use a bottle of Lucus stop slip and if that doesn’t solve the issue, I’ll weigh the cost difference between a repair and a replacement. Unless you can provide any other probable solutions. I’m an amateur….
@@slow_restoration How important is it to replace the throttle body sensor if I am experiencing shift problems? How likely (without you having diagnosed my transmission) will the throttle body sensor solve the issue?
Hey thanks for your video. One question, does this fix help the shift from gear 1 to 2? I’m experiencing a real sluggish shift from 1 to 2... Seems to hang around the 1500 rpm mark for a few seconds, before finally shifting into 2.
Great video very easy to understand. .,….I got 2006 Chevy suburban 4x4 same shifting problems. Shifting just like say. What you think should I buy the parts l that you replace?
Absolutely terrific video my friend thank you very much. I'm having rather I believe a similar issue I have a 99 Chevy Silverado 1500 2 wheel drive and the transmission is rather skipping 2nd and 4th gear do you code come up that the shift solenoid was bad so I put two new solenoid and it today and it's still doing the same thing the question is do you think that this Corvette Servo would be my issue I would very much like your opinion and again thank you very very much for this video
Check the ground wire connection from transmission to frame and ECM to firewall.. bad poor ground causes it to go in to limp mode common problem 4l60 e and silverado
if going to this point, why didn't you drop the pan and change the filter? not capping on ya, but I would have done a service as the vehicle is already on the lift.
Hey Danny hopefully u can help me, I have a Cadillac Escalade ext 07 and literally today a few hrs ago I tried to put it on drive and it stayed on Neutral; the gear stick would go all the way up and down but the truck would stay on N, Idk what could be, could be a shift cable broken or a shift interlock? Help!
If the shifter moves without any detents and there's very little resistance it's a good possibility its in the cable or it came unhooked. This would be easy to check if you can get under it and look at the trans linkage. Just make sure the wheels are chocked.
Quick question. My 07 Avalanche just went to limp mode and would only drive in gear 1 and 2. Not 3 or D. Checked the fluid and was completely dry. Added trans fluid and no difference except I now have a slow leak and I can shift to 3 and D when my speed gets up. So I have to manually shit to D and has very little power. And I recently just been pulling a trailer over the weekend moving.
So kind of a problem here I'm trying to do this on my 03 Sierra I get too the last part of the servo but the end of the pin hits on part of the truck and I can't get it out
I have a 2004 GMC Sierra and I have a little sleep between 2to 3rd gear, I'm pretty sure This is the solution for my truck and your video helps me a lot to do my truck, It is a really good video, my question Is how I can found this in Amazon do you have any part number or something
I ordered the corvette shift servo from Amazon (Fully assembled unit incl cover $63) and this did not fix the problem, I suspect ours may be a total pump failure. We had the same issue described in the video, long double shift 1st to 2nd, and very slow 4-5 second shift 2nd to 3rd, we bought our Escalade exactly 1 year ago with this problem and have driven it this long so most likely not a clutch friction plate issue. A few days before replacing the shift servo the vehicle completely lost ability to shift to any gear but still worked in 1st gear. After replacing the servo it restored shift 1st to 2nd back to doing its strange double shift again, but unable to shift 2nd to 3rd or beyond.
3-4 clutch is pretty weak on the 4l60e unfortunately, if you drive around with a leaking internal seal or any clutch slip you will fry the 3-4 clutches eventually and will need to replace them.
I have 2003 hummer h2 that had slipping shift from 3-4 with 175k miles on it. I tried the vette servo and now it won’t drive at all. So I put the old one back in and still no movement. Any ideas as what happened?
If my tranny fluid smells really burnt is it too late to think that this will fix anything? The car still shifts from 1 to 2 but 2 to 3 or 3 to 4 revs up before switching gears. I drove it about 10 miles not knowing that the fluid was really low.
Having hard shifts when slowing to enter a roundabout and accelerating coming out of the roundabout. Also sometimes after slowing to go over a speed bump and then accelerating once I get off the speed bump. 2008 suburban k1500 Ltz
Does this only apply between first and second or would it also help soft shifts between two and three as well as three and four no slipping once engaged, but when transitioning from 2 to 3 and 3 to 4 sit slips
my 07 tahoe is slipping between 2-3 and sometimes bangs hard into gear moving the vehicle forward.. started happening after a bad ground was causing stalls and misfires.. makes me hate all this computer crap, but i want to try and tune it out using software.. make it shift sooner or later to solve it..
02 Chevy Suburban and I'm starting to believe AAMCO failed to repair my transmission. A custom rebuilt transmission($2909.09) and the transmission is still seem to slip as I give it gas attempting to increase my speed from 45 to 50. Now with this rebuilt transmission I can come to a complete stop, give it some gas to go and the transmission slips before going into gear. Going back in the morning to complain about the repair not being fixed.
Hello Sir, i got 2005 cadillac Escalade esv i has the transmission Rebuild in the pasted 5 years last month the Engine is Bad and I let the Mechanic do the Engine Swap and then I drove home about 15 miles I'm about 2 miles away from my house then the Transmission is start to Acting up just like in this video and I kept drove it about 1/4 mile Now the transmission is free even I put in any Gears it won't move at all. Do you Think the Corvett Servo is Bad? Help me Please Sir. i had been spented a lots of Money into this car in the last 5 years. It's over $6000 Already so far in the pass 5 years.
@@slow_restoration Sir, i'm puting everything back together now but i having a trouble putting on the snap Ring. snap ring is a last thing right? push in a Servo and force in the snap ring until it lock Right? Please help me Sir, Thanks!
Eh. Mine has 339k on the original motor and transmission and I'm just now replacing shift solenoids. I didn't have any transmission problems other than the occasional wierd shift until I let it sit a year through quarantine. The shift issue wasn't bad enough to be worth fooling with before, but since I have to get under there to fix the other issue now I may as well check this out. There's no time for a rebuild or money for a replacement, so we'll see if this can get me to work and back for awhile longer... Wish me luck, send good vibes, and don't bad mouth my high-mileage truck. 😆 Until I get this one right, I'm having to drive a Ford that was bought as a project. It gets me where I need to go, but not with any degree of comfort or dignity. The damned driver's door stuck yesterday and I had to choose the window or passenger side exit. FYI, I tried both - neither can be done gracefully when coworkers are watching. 🤣
ok...ive been involved in this project for 6 weeks now....thankfully its not my daily driver. road grime had yhis thing allmost like welded into place. Then last week.it actually moved for me and i got it out. now i cant seem to get this thing in deep enuff to put the covers snap ring back on....it will go but be patient. im thinking my crowbars the tool to use instead of the pry bar....i came down with lyme the same day i got the servo out so the fevers wreaking havoc with me. The fluids just horrible though. not cooked, yet but pretty bad.....so how can i drain the converter safely? ive done this with th350s back in the day by cutting the top feed trans line on the radiator ....couple 3ft pieces of fuel line. the end i left in the radiator i put the line into my new fluid....the other end off the tranny was just to empty it all out. my rebuilds a vette servo now and i used to use trick shift alot too back on the 80s....is this ok with the 4l60e? and lucas too. my trannys were better than new and trickshifts allmost like putting in a shift kit too. I got my scripts for lyme today and im feeling my oats allready after just the 1st pill....im not working till sunday so theres time. Its thurs now. pretty excited sbout this whole thing...its my 01 silverado and i miss it
I have a 96 caprice lt1 just bought it drove it all the way from Montana to Ohio without any problems it drove sweet few day later I seen a drip then few more days later a puddle and it wouldn't shift out of second gear then I had to keep cutting car of start back up go a lil bit and same thing but bad leack should I do lines filter flush an corvette servo please help car road perfect until it start leaking started as a drip then puddle and put computer on it and it said pcm???????

Can't wait to see a video.too fix my 92 chevy van 4l80e doesn't shift into 3rd or 4th.in lim mode.showed code 81,82. 2 master mechanics cannot figure it out.of and on problem for years
It would be nice if u had focus on the speed or accelerate at least up to 100 to show the difference between when you did the test drive & after great video but not convinced that it works with driving same speed limit but u sound true cause the part was worn out just saying
so your only symptom was "sluggish shift?" Not sure what that means. I was going to replace all of my solenoids, but this looks much easier . I want to believe.
Servicing helps. Lettings that old worn out fluid try to lube things for 200k+ just aint the game. That said even one without regular servicing ive seen some hit nearly 300k before failure. These arent as horrible transmissions as people make them out to be. Infact ive seen more fail are higher mileage due to low fluid levels. Transfer case input seal goes bad then you end up with a good portion of your trans fluid, in your transfer case.
Great content. However, this dude would do himself a favor by getting a bench to work off of. Doing this servo breakdown and rebuild on a piece of cardboard stretched across the engine bay of a truck hulk is a bit prehistoric. Good stuff though.
its the quality of work done, not how shiny and pretty your tools are. i see a desk that looks like it was just bought it tells me the guy does no work. i would love to have had a work bench and lifts and all the other goodies but most of us use what we have.
The CV Servo affects the into 2 & 4th gear shifts making them "claimed" firmer & quicker . Very likely , you have an issue inside your valve body or 2nd gear accumulator .
Is your harsh 1-2 shift intermittent? If so, it could be a wiring harness problem. Actually even if it’s not intermittent that can be true. Try disconnecting and reconnecting the wiring harness connection to the transmission to remove any oxidation and improve the contact. Free to do and not so difficult.
An Escalade is too large to have a Corvette servo installed. If you really want to help people fix their transmission. You tell them to drop the pan and change the filter first.
@@slow_restoration After a while, you will get tired of the hard shift to 2nd gear at full throttle. Drop the valve body, take it apart, clean it and replace the separator plate. Buy new "stock" servo seals and it want lose pressure anymore.
