Due to the new vent locations and the amount of bore wear on Ford/GM GEN2 FWD 6-SPD units, these valve bodies have common leakage issues that require one simple, single diameter ream of the actuator feed limit valve on GM units and solenoid regulator valve on Ford units. To make it easy for builders, TransGo engineered one universal toolkit for use with these GEN2 Shift Kits® with reusable reamer and 3 grooved sleeves.
