Description:
In GM 4L60E, 4L65E and 4L70E units it is common to have poor shift quality, burnt bands or clutches due to accumulator piston wear. Repeated reciprocation of the accumulator piston causes wear at the piston pin bore interface. After this wear reaches a critical point, fluid loss through the piston pin bore cannot be compensated due to lack of pump volume. In addition, the piston can get cocked and gall the accumulator bore due to the pin bore wear or the spring bottoming out. This kit prevents these conditions in the 1-2 or 3-4 accumulator bores.

Pinless design eliminates the possibility of pin bore leakage and the additional length stabilizes the piston to prevent piston cocking.
Dual seals stabilize and completely seal the bore and provide a tight seal even after thousands of cycles.
Steel balls plug existing pin bore in case or cover.
This transmission requires 2 of these pistons. This listing is for one item.
