Contents

Directions
This kit is designed to change the capacity of the GM 4L80E Forward Clutch Pack from five (5) friction discs to seven (7) friction discs. Discard the bottom disc cushion spring and install the bottom pressure plate. Continue the stack-up by alternately installing the remaining friction disc and steel plate, ending with a friction disc.
Note: This kit will eliminate the bottom disc cushion spring, which will cause the unit to have a much firmer garage shift to forward gears.
Check clutch pack clearance from the top of the friction disc to the bottom of the pressure plate ledge, using a feeler gauge. Clearance should be .040” - .055” (1.02mm – 1.40mm).
