6L80 Troubleshooting PT3 - Hydraulics: Valve Body and Pump Stator Support

Описание к видео 6L80 Troubleshooting PT3 - Hydraulics: Valve Body and Pump Stator Support

I continue the General Motors 6L diagnosis and troubleshooting series with a deep dive into the valve body and pump stator support (aka pump cover) including an overview of the valve body and role that it plays in the function of the transmission, common drivability symptoms associated with the valve body and a comprehensive vacuum test of the upper and lower assemblies.

I also explore the pump cover and associated hydraulic circuitry, performing a vacuum test of the four hydraulic circuits located in the cover and show what a worn pressure regulator valve looks like.
