Vehicles with a THM 700-R4 or 4L60-E transmission may experience band failure due to insufficient holding power of the 4th gear servo piston. Install the Sonnax replacement 4th gear servo piston, "The Sonnax Super-Hold Servo," 77767K. The surface area of the new piston has been increased by 40% to increase its holding power. The improved Sonnax piston installs easily into any 700-R4 or 4L60-E application without having to remove the transmission from the vehicle. The new Sonnax piston assembly comes complete with piston, housing, and all the seals necessary to install the assembly. Also available from Sonnax to go with the 700-R4 servo is a replacement seal kit 77767K-SK.
