TRANSMISSION 11 Valve body and TECHM assembly: The valve body assembly includes the 2 channeling plates, gasket, TECHM, Internal Mode Switch (IMS) and Transmission Input Speed Sensor (TISS) and Transmission Output Speed Sensor (TOSS) wires. The TCU commands shift solenoids and variable bleed pressure control solenoids to control shift timing and feel. The TCU also controls the apply and release of the torque converter clutch which allows the engine. The TCU is located in the transmission oil pan. Electrical signals from various sensors provide information to TCU about vehicle speed, throttle position, engine coolant temperature, transmission fluid temperature, gear range selector position, engine speed, converter turbine speed, engine load braking and operating mode etc. The TCU uses this information to determine the precise moment to upshift or downshift, apply or release the TCC, and what fluid pressure is needed to apply the clutches. This type of control provides consistent and precise shift points and shift quality based on the operating conditions... Transmission Electro-Hydraulically Control Module (TEHCM): The TCU, the shift solenoids, the pressure control solenoids, the transmission fluid temperature sensor are packaged into a self contained control unit, the Transmission Electro-Hydraulically Control Module (TEHCM) bolted on the valve body Note: This is for information only. Disassembly of this component is not allowed. Transmission 16-Way Connector Description: The TEHCM connects to the vehicle harness 16- way connector via a pass-thru sleeve.
