Overview
Summit Racing™ Automatic Transmission Servo Kits
Summit Racing™ Corvette-style servo piston kits allow you to swap out your OEM servo on your 700R4 or 4L60E/4L65E automatic transmission and improve shift quality and firmness. They have a larger piston area which increases band-apply pressure and holding power. These kits are drop-in upgrades and will really firm up the 1-2 shift. Includes both pistons and all necessary O-rings.
