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 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!
