Toyota U140/240/241/150/151/250, A750/760/761/960/AB60 Accumulator piston
The original Toyota accumulator pistons have no seals and rely solely on the close tolerances of the components, (when new) to control system leaks. However, over time and with use, the soft aluminum accumulator pistons and the valve body bores wear, creating leaks resulting in shift feel complaints and burnt friction discs. The TransGo solution utilizes made-in-USA hardened steel accumulator pistons fitted with scarf-cut sealing rings to provide a good seal in worn out valve body bores, even in a less than perfect bore that would normally damage any rubber seals.

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.
