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.

Sonnax oversized pressure regulator valve 92835-29 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

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. Non-VLP units can be serviced with Sonnax 92835-24.
