4L30E [89-UP] Automatic Transmission Piston Overrun Clutch (Bonded)

Lip seals take a set in the groove and stop wiping the bore the way they did when new.

4L30E overrun clutch (bonded) piston. This piston set restores a positive seal so the pack applies with full pressure behind it.

Seal orientation determines whether the piston holds pressure or vents it. The pistons are bonded rather than lip sealed. Shipping weight is 1 lb.
