Sonnax LPC Signal Damper Piston Kits

Sonnax LPC signal damper piston kits are specialized automotive repair components designed to fix worn valve body bores, stop harsh transmission shifts, and stabilize line pressure in select Ford and GM 10-speed transmissions.

Additional details:

* Dampens pressure spikes: Stops fluid surges in the EPC/LP signal circuit from hitting the main pressure regulator valve
* Fixes wear issues: Repairs worn valve body bores and pistons that leak fluid to the exhaust
* Stops symptoms: Prevents unwanted pressure changes, excessive line pressure, and rough shifting
* Kit features and design:
-- No reaming required: Drops directly into the lower valve body casting for a quick fix
-- Positive O-ring seal: Prevents pressure loss even inside already worn cylinder bores
-- Durable materials: Uses a hardcoat anodized aluminum piston with an annular groove and a wear-resistant sleeve to block future damage
