Details:

Position: front. Model: accumulator piston kit. In 200-4r applications, this kit can only be used in the 3-4 accumulator location. For gm units it is common to have poor shift quality, burnt bands or clutches due accumulator piston wear.

Manufacturer: Eatakward. Brand: Eatakward. After this wear reaches a critical point, fluid loss through the piston pin bore cannot be compensated due to lack of pump volume. Replace part number: 77987-01k, 7798-03k 2pc.

Manufacturer part number: /. This causes a loss of fluid, resulting in delayed engagement, slips, burnt clutches and/or bands. Dual seals stabilize and completely seal the bore provide a tight even after thousands of cycles. Repeated reciprocation of the accumulator piston causes pin bore to wear, while fluid loss through or cracks forward clutch slip.

In addition, the piston can get cocked and gall accumulator bore due to pin wear or spring bottoming out. Steel balls plug existing pin bore in case or cover. Exterior: as shown. Repeated reciprocation of the accumulator piston causes wear at pin bore interface.

For 4l60-e, 4l65-e and 4l70-e units, it is common for the plastic forward accumulator piston to wear or crack. Accumulator piston kit for 4L60E 4L65E 4L70E transmission pinless 1-2 3-4: .
