Sonnax Main Pressure Regulator Valve Kit Fits Ford 10L60/80/90G1
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 transmissions. This wear minimizes line pressure control resulting in delayed shift engagement, poor shift quality and burnt clutches. Wear at the inboard spool and bore can lead to converter apply issues.
Installing the drop-in Sonnax main pressure regulator valve kit 105740-12K 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, so actuates in unworn areas of the bore. 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.
- Extended outboard spool is 270% longer than OE and actuates in unworn areas of the bore
- O-Ringed end plug provides positive seal to prevent critical signal fluid from leaking to exhaust
- Hardcoat anodized aluminum valve combats premature wear
- Drop-in Zip Valve parts install quickly and easily
