Oversize Pressure Regulator Valve* Reamer Required Units with VLP Solenoid Only
O/S PRESSURE REGULATOR VALVE VLP UNITS
Symptoms:
Shift concerns
Low line pressure
High line pressure
Erratic TCC apply
Poor lube oil control
Cause:
Worn pressure regulator bore
Correction:
This valve restores the pressure regulator circuit with an oversized pressure regulator valve that returns pressure regulation to like-new function.
Fits VLP 40TES, 41AE, 41TES, 42RLE only.
Sonnax oversized pressure regulator valve addresses high/low line pressure, harsh shifts, erratic TCC apply pressures and poor lube control in 41TE(S), 42RLE and 62TE units. Wear is commonly found at different areas in the pressure regulator bore. Wear at the inner bore causes high line pressure, harsh shifting and erratic converter apply pressure. Wear at the spring end of the bore allows line pressure to exhaust, resulting in low line pressure, soft shifts and burnt clutches. Wear at this area also will affect converter flow and the lube circuit. The Sonnax valve restores valve-to-bore clearances, allowing the pressure regulator valve to maintain correct pressures in all ranges.
Sonnax aluminum valve is hard-coat anodized for wear resistance
Oversized valve has annular grooves to support valve and reduce wear
Note:
This Sonnax valve fits 41TE(S), 42RLE units with variable line pressure (VLP) solenoid only. VLP units can be identified by the presence of the line pressure solenoid and transducer mounted on the valve body.
