Press.reg. valve 6L45, 6L80, 6L90 OS

Press.reg. valve 6L45, 6L80, 6L90 OS Valve Drill Bit Checkballs (2) 1 Extra Hardcoat anodized aluminum valve combats premature wear Lengthened critical spools operate in non-worn portion of bore for added stability and wear prevention. Annular grooves help center valve in bore to reduce future side-load wear No reaming or special tools required Symptoms: Burnt clutches Clutch slippage Converter concerns Harsh shifts High line pressure Low cooler flow Low line pressure No cooler flow Overheated transmission Soft shifts Cause: Continuous oscillation of pressure regulator valve results in excess bore wear, causing erratic line pressure and/or restricting cooler/lube flow. Correction: Recover hydraulic control and renew line pressue performance by installing Sonnax pressure regulator valve kit. NOTE: Pump must be removed to install kit. superseeds 104520-03K
