AW 50-40 50-42 LE Transmission Solenoid Kit AW Volvo Saab New
Restore precise line pressure and eliminate torque converter shudder with this complete 3-piece solenoid pack engineered specifically for the Aisin Warner AW 50-40 and AW 50-42 LE transmissions. Designed as a direct replacement for the AF14-20 hydraulic architecture, the package includes one torque converter clutch (TCC) lock-up solenoid and two directional shift solenoids built to restore factory calibration during a valve body service or transmission rebuild.
Fitting relies entirely on your connector configuration. Before purchase, visually verify that your transmission shift solenoids require green electrical connectors. Gearboxes fitted with gray connectors are incompatible and this kit will not mount or wire correctly. The assembly covers AW 50-40LE and AW 50-42LE variants manufactured from the 1989 model year onward, which are commonly specified in vintage Volvo and Saab automatic drivetrains. Each internal valve and electronic component arrives sealed in its original box, ensuring zero prior wear and immediate installation readiness.
A degraded lock-up or shift solenoid typically manifests as delayed gear engagement, harsh downshifts, or continuous slippage under acceleration. Replacing both shift valves simultaneously prevents uneven hydraulic pressure distribution and stabilizes torque conversion across all operating temperatures. Confirm your connector color and transmission casting number to guarantee an exact physical and electrical match before completion.
