I have no idea what happened, everything seemed to go in without much trouble, I did have to put a good amount of force on the cover to get the snap ring to seat, but seemed normal from everone elses posts.

The servo cover snap ring was cocked halfway out and letting the cover leak. Its a small chip from one of the little access notches on the servo boss diagonally outward. In an older transmission, it might also help lengthen life too.So I installed the Corvette servo in my 2007 Classic 2wd 1500 and it felt great for 2 days.then my truck doesnt want to shift to second and is dumping fluid out on the highway. In a new vehicle, it will make the transmission last longer. When people who have done the mod post about it, they all seem to love it and say that under normal driving, the shift feels the same, but when accelerating hard, the shift is quicker, but nothing bothersome.Īnother question is whether the Corvette Servo safe for all vehicles? Is there a mileage or age where it becomes risky? According to the hype, the answer is no. It seems that when most people ask the pros at their local transmission shops and then post about it online, they are advised not to do it because they will hate the hard shifts. With this mod, you are supposed to get quicker/firmer shifts and a transmission that will last longer, with no associated complications. I've done a lot a reading and come to the conclusion that there is a lot of hype around this mod and I can't distinguish what is real and what is not. It sounds like the perfect way to upgrade my transmission and a mod that will work with the BB tune later. It's cost is between $20-$80 depending on which kit you choose, and is a simple upgrade that can be done in the driveway in about an hour. I originally thought that the way to firm up the transmission was through a custom tune, which will be in my truck's future, but then I stumbled on the Corvette Servo. They jar the whole truck, even when accelerating lightly. The transmission on my 95 Chevy was rebuilt before I bought it and the shifts are hard and quick.

Is the Corvette Servo a gimmick bolt-on like the throttle body spacer and cold air intake, a legitimate performance mod like the Black Bear Performance tune, or an neutral item like a cat back exhaust system that sounds good and makes you feel better about your truck, but has negligible performance gains and no real negatives?
