This TransGo 6L80 SHIFT KIT® Valve Body Repair Kit fits 2006 to 2018 General Motors and BMW vehicles equipped with the popular 6L45, 6L50, 6L80 and 6L90 automatic transmissions. These transmissions often come in with a delaminating Pressure Regulator (PR) valve which wears out the PR valve bore in the pump causing erratic line pressure. Another area of wear concern is the solenoid regulator valve bore. Wear in both areas can cause various shift complaints and codes, delayed engagements and broken hard parts due to high pressure spikes.
Features and benefits:
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.
