Relevance: Exact
Complaints: Delayed engagements, slipping in forward gears, burnt clutches and/or bands, plastic pistons crack and are not durable, aluminum pistons wear at the pin bore Cause: Wear at the piston pin bore due to repeated reciprocation and/or cracks in the plastic accumulator piston. Correction: The Sonnax kit's dual seals stabilizes and completely seals the piston in the bore. In GM 4L60-E, 4L65-E and 4L70-E units it is common for the plastic forward accumulator piston to wear or crack. This causes a loss of fluid, resulting in delayed engagement, slips, burnt clutches and/or bands. Repeated reciprocation of the accumulator piston causes the piston pin bore to wear, while fluid loss through the piston pin bore or cracks causes forward clutch to slip. Sonnax pinless forward accumulator piston kit 77987-01K eliminates these problems.
Dual seals stabilize and completely seal the bore, providing a tight seal
Pinless design eliminates the possibility of pin leakage
Includes steel balls for plugging existing pin bore in valve body

Complaints: Burnt clutches & bands and poor shift quality. Cause: Wear at the piston pin bore due to repeated reciprocation. Correction: The Sonnax patented pinless design with dual seals stabilizes the piston in the bore and provides improved sealing characteristics. Use of the Sonnax part eliminates the need for the pins. In GM 4L60-E, 4L65-E and 4L70-E 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. To prevent these conditions in the 1-2 or 3-4 accumulator bores, Sonnax offers pinless accumulator piston kit 77998-03K.
