6L80E / 6L90E TransGo Pressure Regulator Valve Repair Kit, 2006-On, 6L8-VL-PR3. (Transmission removal is required for this kit.)
2006 and later General Motors and BMW vehicles that are equipped with 6L45, 6L50, 6L80 and 6L90 automatic transmissions often wear out the line pressure regulator (PR) valve and bore.
The purpose of the PR valve is to regulate the transmission line pressure. On one hand, if the PR bore wear is severe enough at the balance end of the valve it can result in erratic or high line pressure. On the other hand, in those cases where the wear is most prevalent at the spring end of the valve, the leak in that area would cause erratic, low or high line pressure. For the same reason, the symptoms will vary as well, ranging from harsh shifts, soft shifts, burnt frictions, overheating, to converter clutch failure.
