Description

Input housing failure at the shaft and forward piston areas is common in high-torque 4L60, 4L60-E, 4L65-E and 4L70-E transmissions. Sonnax input housing forward sleeve kit 77733-52K is used in combination with a Sonnax overrun sleeve to greatly increase the maximum strength of the housing and prevent these failures.
