Input Drum Reinforcement Kit, Sleeve,Seal & Piston, 4L60/60E-65E/70E **No machining Required**

The GM 4L60, 4L60-E, 4L65E and 4L70E input drum assembly is known to crack where the input shaft is pressed into it (where the overrun clutch rides). Sonnax now offers this hardened steel sleeve that reinforces the input drum to prevent this failure. No machining is required to use the 77733-01K kit. OEM overrun pistons must be machined when using the 77733-02K kit.

**Notes: Will not repair a cracked drum. Late-model stamped forward pistons must be replaced with early-style cast-aluminum forward pistons.

Sleeve made from hardened Chrome-moly steel

Includes a reworked OEM piston and o-ring

Can be installed in earlyand late-model units*

Sleeve design will not block clutch feed oil
