4L60E 4L65E FORWARD DUAL SEAL ACCUMULATOR PISTON

Description

You are buying a dual seal forward accumulator piston for all 4L60E’s and 4L65E transmissions.

• Fits all 4L60E series, 1993 and up
• This accumulator piston uses two seals, unlike the OE piston, to eliminate pin wear
• The stock piston can accumulate pin wear in as little as 25k miles, this causes a hydraulic circuit cross leak and a loss of functionality
• In addition, we have seen the pinless versions cock in the bore and get stuck
• This one solves the problem by providing two seals and uses the pin to stabilize the piston in the bore
• The seals are included
