Sonnax has introduced a new line of LPC signal damper piston kits for Ford and GM 10-speed transmissions. Sonnax says these kits can correct EPC circuit pressure variation for these transmissions by replacing the worn OE damper and installing the appropriate kit. The kits install without the need of reaming the valve body.
