    Avoid Converter Clutch Slippage with a Quality Accumulator Piston

    A transmission accumulator piston dampens shift solenoid movement and controls the initial regulation rate of the converter clutch regulator valve. Over time, they wear out and can cause engagement issues. Trans Go offers quality Accumulator Piston Kits to restore functionality when rebuilding your automatic transmission.
