High performance Corvette Servo Piston Assembly with Cover, Snap Ring and Pin for GM 1982-2014 700R4 4L60E 4L65E 4L70E Transmissions

⭐⭐⭐⭐⭐ I recently upgraded my 4L60E transmission with a Corvette servo, and I can’t express how remarkable of a difference it has made! Initially, I was somewhat skeptical about how much an inexpensive part could enhance my driving experience, but it truly exceeded all my expectations. First off, the install was surprisingly straightforward. The instructions provided were clear, making even this DIY novice feel confident as I tackled the project. Once I had the servo in place, I noticed an immediate improvement in the shifting responsiveness. Gears engaged smoothly and without hesitation, which gave my driving an enhanced sportier feel. Performance-wise, my vehicle feels much more connected—like I’m truly in control rather than just along for the ride. The shift points are more precise and aggressive, especially during acceleration. There's a definite boost in confidence when making merges or quick lane changes, all thanks to the improved shift firmness. It's like turning my everyday drive into a mini racing experience! I cannot overlook how this mod brought life back into my transmission as well. The Corvette servo reduced the soft shifts that I used to experience, leading to less wear over time. I believe this will contribute to the longevity of the transmission, and that's always a bonus! Overall, this Corvette servo is a must-have for anyone looking to revive their 4L60E transmission. Not only is it an affordable upgrade, but the performance enhancement is like night and day. If you're throwing around the idea, trust me: just do it. You won’t regret it! Highly recommend!

Worked great and firmed up the shifts on 2004 Trailblazer w/4l65e

Great product that I installed on my 03 Tahoe. I would say however that the black rubber gaskets did tear easily but other than that it was a smooth install. It really firms up my 1-2shift I still have to let off so it didn’t solve that problem but when I do let off it shifts immediately and hard. Better than the stock.

Worked great for me, have 03 suburban and had sloppy shifting, it shifts earlier and stiffer now, super easy to install too Had for about a year now and no issues

Installation was a little harder since transmission was in a running car but still not too bad. Noticeable improvement in 1 and 2 shifting. Great product for great price

Less then 100 yards had complete failure it literally fell apart. So had to take out again and put the factory parts back in . The gaskets are hard and old .took for a test drive and had no 4th tore it down and there was pieces that locked other parts into place it was a pain to get out . Don't waist your time or cash

works great no issues

It fit my 08 4l60e with no issues. For the people that say it dont fit in the opening if it's loose you'll leak fluid. Yes its a pain in ass take a big screw driver or a tire iron get it started by hand once your sure its aligned proper stick the bar between the floor and on the back of it and pry it in the biggest PIA is the retaining ring I didnt even use what came with it i used my old one. As far as feel a improvement well my granny wad cook before so dont really feel much diffeent. The only thing I had to do was remove the heat shield on side of trans ,didnt have to remove or drop anything and took about 15 minutes. On my 08 tahoe ltz.

Excelente

The seal is bad on mine, there was an 1/8" gap, not cut on an angle like they are supposed to be, so my subunan didn't shift right, I'd like a discount since I had to remove it and use the seal from my original unit... but no way to get customer service. Useless system!

Installed then went on road trip would not shift into second till a really high RPM then it slid in .Removed looked for a problem. Installed 3 more times same thing .Reinstalled my old one and it works fine. Six hours of messing around and plus I knocked the container over with trans fluid in it half way through . NOT REALLY Happy
