![]() The TCM uses these inputs to make decisions and activate actuators like shift solenoids, the TCC solenoid, EPS solenoid, and coast-timing solenoids. Pressure Sensors: The TCM uses these sensors to verify that the desired hydraulic circuit is under pressure. It's compared to the (VSS) vehicle speed sensor's signal to monitor performance. OSS: The output shaft speed sensor informs the TCM of output shaft speed. Each unit is engineered to meet or exceed. TSS: The turbine shaft speed sensor informs the TCM of turbine shaft speed. A1 CARDONE Remanufactured Transmission Control Modules are engineered for quick installation and no comebacks. The TCM uses this information to monitor the transmission's fluid temperature. TFT: The transmission fluid temperature sensor is located inside the transmission. At (WOT) wide-open throttle, the TCM downshifts. The TCM uses this information to control shift timing. TPS: The throttle position sensor informs the PCM of the throttle angle. The TCM uses this information for shift timing, line pressure, and TCC application. It senses the mass of airflow in the air tube before it enters the intake manifold. MAF: The mass airflow sensor informs the PCM of engine load. The TCM uses this input to delay the TCC application until the engine reaches operating temperature. The TCM uses this signal to control the TCC.ĮCT: The engine coolant temperature sensor monitors engine coolant temperature. Busbee used trucks and parts - Computer Control Module - Transmission - TCM - Parts for medium duty imported diesel trucks: Isuzu, Mitsubishi Fuso, Hino. Automatic Transmission Sensorsīrake switch: The brake switch signals the computer when the brakes are applied. ![]() Sensors detect conditions such as movement or pressure and convert them into an electrical signal for the TCM. The TCM also receives information from sensors shared over the CAN multiplex network with the PCM. In this case, it’s crucial to bring your car in for repair right away. However, when the transmission fails to respond immediately, you may experience a brief delay before your car can move faster. ![]() The TCM has preset data to compare these inputs and make the appropriate decision. Generally, the transmission control module responds when you switch gears to accelerate, which allows your car to move faster. It receives input from various sensors to activate the various solenoids, the (TCC) torque converter clutch, control line pressure, and provide smooth shift timing. The (TCM) transmission control module can be a standalone controller or located in the (PCM) powertrain control module. ![]()
