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

Slides right in, quality looks equal or better than stock, cheap upgrade for your 4l60e. I recommend taking the last two pieces behind the cap off and installing the main component, it will just save you time trying to get it in that tight spot, lube the o rings before forcing the cap on

⭐⭐⭐⭐⭐ 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!

Works great truck now shifts like it should. Hard to get the snap ring in that holds the assembly into the transmission. It takes a lot of patience. Just make sure it is seated all the way around, otherwise the cover will pop out and you will loose fluid.

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

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.

I have a 2000 Chevy Silverado with a 4L60E My 2nd gear would slip SOOOO BADDDD this pretty much 100 removed it Would recommend. 2 things tho 1.Had to use stock cap because the red one was to thick to fit 2.if you can’t put servo in all the way when installing snap ring then hammer it in gently (No such thing as having to move the band)

Over all its a good pruduct, i have been running it on my 4l60e and it made it feel way better when shifthing one thing that you do need to make sure is that you lubercate the parts properly and install it all the way or it will pop out and leave you stranded.

The servo failed causing the transmission to slip and burn up 2/3 clutchs

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
