1. Replace Part Number 77987-01K, 7798-03K2PC. In 200-4R applications, this kit can only be used in the 3-4 accumulator location. 2. For GM 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, we offer pinless accumulator piston kit 77998-03K. 3. For 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 andor 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. Our 77987-01K dual seals stabilize and completely seal the bore and provide a tight seal even after thousands of cycles Pinless design eliminates the possibility of pin leakage, and the additional length stabilizes the piston to prevent piston cocking. 4. 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.. 5. Pinless design eliminates the possibility of pin bore leakage and the additional length stabilizes the piston to prevent piston cocking..

Direct Replacement Due to the repeated reciprocating movement, the old plastic piston pin hole is very easy to wear and tear, and the lost fluid will cause the forward clutch to slip, which will lead to start shaking and difficult to shift to the first and second gears. It is recommended that you replace it in time. This aluminum sealed pinless accumulator piston kit meets or exceeds the oem standard, and has passed the factory test, fully matches the original car, can be installed directly. High Quilty Using enhanced materials, wear resistance, high temperature resistance, corrosion resistance, and long service life. The pinless design eliminates the possibility of pin leakage, and precision steel balls can additionally be used to plug the existing pin holes in the housing or coverso as to ensure precise sealing. Replace with a new piston kit, improve gear shifting and extend the life of the strap and clutch, providing you with long-term stable and excellent performance.
