This 6L80 Shift
Kit fits 2006 and newer General Motors 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:
This TransGo Shift 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.
