Transmission Control Module Function
The Transmission Control Module (TCM) J217 receives information from the components that affect the shifts and forwards this information to the pressure regulator valves of the valve body, which control the slide valves in the valve body.
The Transmission Control Module (TCM) J217 is mounted at the rear of the transmission, directly on the hydraulic unit. The following components are integrated in the control module. - A - Transmission Output Speed (RPM) Sensor G195 and Transmission Output Speed (RPM) Sensor 2 G196 , - B - Transmission Fluid Temperature Sensor G93 , - C - Multi-Function Transmission Range (TR) Switch F125 , - D - Transmission Input Speed (RPM) Sensor G182 , - E - Automatic Transmission Hydraulic Pressure Sensor 1 G193 and - F - Automatic Transmission Hydraulic Pressure Sensor 2 G194. These components are not serviced separately.
