MECHATRONIC Valve Block: Notes
The Mechatronic valve block is located in the bottom of the transmission and is covered by the fluid pan. The valve block houses the transmission control module (TCM), electrical actuators, speed sensors and control valves which provide all electro-hydraulic control for all transmission functions. The Mechatronic valve block comprises the following components:
- transmission control module (TCM)
- Six pressure regulator solenoids
- One shift control solenoid
- One damper
- Twenty one hydraulic spool valves
- Manually operated selector valve
- Temperature sensor
- Turbine speed sensor
- Output shaft speed sensor.
