5R55 [02-UP] Automatic Transmission Piston REV Servo Bonded Hiper-blue

A piston that leaks past its seal applies the pack slowly, and slow apply is what burns friction material.

5R55W PISTON REV SERVO BONDED HIPER-BLUE 1.656 5R55 S W N. These pistons return the pack to the apply rate it was designed around.

Apply pressure has to reach the pack without bleeding past the piston to do any work. The pistons are bonded rather than lip sealed. Shipping weight is 1 lb.
