TransGo Performance Automatic Transmission Shift Kit - SK 6L80

The kit utilizes all drop-in valves for quick, no-hassle install, without reaming or tooling. The precision ground USA-made hardened steel PR valve provides full-time line-to-lube and restores the hydraulic integrity of the circuit. It has re-positioned longer lands at both ends of the valves which promote better support less wear. As a result, this new valve is a drop-in fix even with a pump that has substantial bore wear. A new boost valve and bushing is also provided with a built in EPC pressure relief to eliminate the possibility of damaging high line pressure spikes. In addition, to address the solenoid regulator valve bore wear, a drop in system using a precision ground USA-made hardened steel valve and a valve guide insert is used. Consequently, it no longer uses the original worn bore and easily restores the hydraulic integrity of the solenoid regulator valve circuit.Finally, the kit includes new rubber seals and diaphragms to renew the TEHCM pressure switches. The kit also includes TransGo engineered high temperature stator rings, to salvage problematic early style pump stator support without locking sealing rings.
