Quick Overview

6L80, 6L45, 6L90, 6L50 PRESSURE REGULATOR KIT 104520-03K


•Cup Plug
•Self-Threading Screw
•Drill Bit

Vehicles with GM 6L45, 6L50, 6L80, 6L90 transmissions may exhibit high/low line pressure, soft/harsh shifts, slipping or burnt clutches and overheating problems. These problems may be caused by continuous oscillation of the pressure regulator valve within the pump cover bore, creating excessive wear and a path for line pressure and converter feed pressure to exhaust. The drop-in Sonnax pressure regulator valve kit 104520-03K has enhanced design features to add stability, work in non-worn areas of the pump cover bore and prevent critical hydraulic leakage.

• Valve is hardcoat anodized to reduce wear

• Lengthened critical valve spools add stability and prevent wear

• Valve works in non-worn areas of the pump cover bore

• Balance feed orifice re-routing tools included in the valve kit to correct line pressure control

• No reaming or special tools required
