Transgo Drop-in Pressure Regulator Valve 4L60E 4L65E 4L70E

Transgo Drop-in Pressure Regulator Valve for 4L60E, 4L65E, 4L70E (1993-2015) In General Motors vehicles from 1993 to 2015 equipped with 4L60E, 4L65E, and 4L70E automatic transmissions, wear on the pressure regulator (PR) valve bore is common over time. When the wear occurs at the balance end of the valve, pressure instability is likely, potentially leading to unregulated high line pressure if the wear is severe. Conversely, wear at the spring end of the valve can cause low line pressure, leading to a range of symptoms such as harsh shifts, soft shifts, burnt frictions, overheating, and converter clutch failure. This precision-engineered drop-in USA-made steel valve provides full-time line-to-lube, restoring the hydraulic integrity of the system without the need for bore machining. The valve’s longer spool lands allow it to function in the non-worn areas of the bore, distributing load over a greater surface area for enhanced durability. Note: Transmission removal is only necessary if th
