Description

Gen 1 10L60 / 10L80 / 10L90 / 10R60 / 10R80 / 10R90 / 10R140 Oversized Main Pressure Regulator Valve Kit, Sonnax 105740-20K.

Wear in the main pressure regulator bore and on the outboard spool area of the valve is common in listed GM and Ford 10-speed RWD transmissions. This wear minimizes line pressure control, resulting in delayed shift engagement, poor shift quality and burnt clutches.

Symptoms:

  • Low line pressure
  • Various shift concerns
  • Delayed engagement
  • Poor shift quality
  • Burnt clutches

Reconditioning the bore and installing Sonnax oversized main pressure regulator valve kit 105740-20K eliminates the leakage of line pressure signal oil to exhaust with the incorporation of an extended front valve spool. This valve spool is 270% longer than the OE spool, allowing for better sealing contact and a more stable operating valve. The O-ringed end plug provides a positive seal and prevents critical signal fluid from leaking to exhaust. Both of these Sonnax features ensure your units will have proper line pressure control through all drive ranges.

Includes:

  • O-Rings (2) 1 Extra
  • Valve
  • Spring Red, Large Dia.
  • Spring Small Dia.
  • End Plug
