Description

4L60, 4L60-E, 4L65-E, 4L70-E Transmission Input Drum Reinforcement Kit Part No. 77733-51KA The GM 4L60, 4L60-E, 4L65-E and 4L70-E input drum assembly is known to crack and strip out splines where the input shaft is pressed into it (where the overrun piston rides). Sonnax offers a hardened steel sleeve that reinforces the input drum to prevent this failure. Sonnax input drum reinforcement kit 77733-51KA includes a custom manufactured overrun piston designed for use only with a stamped steel forward piston, eliminating the need to use aluminum forward pistons. Custom overrun piston works with steel forward piston Chromoly steel sleeve design will not block clutch feed oil Universal design fits both early- and late-model units Contents Reinforcement Sleeve Overrun Piston Inner Seal Overrun Piston Overrun Piston Outer Seal
