Upgrading to the vette servo gives the trans more 'holding' power and thus yields a quicker/firmer shift. The servo is used to apply the 2-4 band in the transmission. From the factory, the truck 4L60e's have a smaller servo. The purpose of the vette servo mod is to allow the transmission to shift more quickly and efficiently from first to second gear. Depending on the exhaust setup, you may have to disassemble the servo assembly in the housing. The servo swap can be performed with the transmission in the truck and also without dropping the transmission pan. The servo is located inside of the servo housing that is located on the passenger side of the transmission. If you have a 4speed auto in your 1500 series, 94 and newer, then it is a 4L60-e, so YES, the vette servo WILL work in it. The 4L60e has remained in the 1/2 ton series truck until present time. In 1994, GM rear-wheel drive vehicles got the new electronic controlled 4L60-e.

The trans remained the same until 1993, although in 93 it was renamed the 4L60. 1982 introduced the 700-R4 trans to the world. Okay, here we go.įirst of all, the addition of a Corvette servo can be done to all 700-R4/4L60e transmissions.

In this thread I am going to attempt to answer more of the questions related to the servo swap instead of writing another how-to on it as both KevinDepot and FatKidKustomz have already completed two thorough install how-to's. I believe there have been 6 threads regarding this just in the last few weeks. Yes, the amount of reoccuring threads inquiring about the additon of a corvette servo has lead me to creating a master thread here.
