Sonnax AW55-50SN AW55-51SN Oversized Pressure Regulator and Boost Valve
OPT Product Code: SNX-59947-12K$111.64
Product Details
Wear at the balance end can cause harsh shifts, high line pressure, converter apply/release problems and lube-related issues. Wear at the other locations can result in soft shifts, low line pressure, and converter problems. Boost sleeve wear reduces the ability of line pressure to rise according to TCM command, resulting in slow line rise and late shifts. Late shifts can often create gear ratio codes. A worn boost sleeve in this unit can also cause a delay in reverse or slippage, eventually burning the low reverse (B3), 1-2 reverse (B5) band and or the direct clutch (C2). Features & Benefits: Boost valve assembly is manufactured from an upgraded highly wear-resistant sleeve and a hard-coat anodized aluminum valve to provide better wear resistance. Replacement pressure regulator valve is hard-coat anodized aluminum to provide better wear resistance than the original steel valve. The pressure regulator valve has longer length spools for increased valve support.
