What is TCM ECU?
A transmission control unit (TCU), also known as a transmission control module (TCM), or a gearbox control unit (GCU), is a type of automotive ECU that is used to control electronic automatic transmissions.
What happens when your ECU goes out?
If the ECU fails completely, it will leave the vehicle without engine management control, and will not start or run as a result. The engine may still crank, but it will not be able to start without the vital inputs from the computer.

When to replace a Transmission Control Module ( TCM )?
Rather than relying on hydraulic or mechanical control over a transmission system, newer vehicles use a transmission control module instead. A car’s TCM will likely never need replacing, but if you have a bad transmission control module, immediate replacement (or repair) will be necessary.
How do you reset the ECU on a Jaguar?
You have to reset the global closing too. Drop each window to bottom, hold “down” button down for 5 seconds then lift the window. Has to be done one by one. • The trip computer will lose all recorded trip data and all trip functions will be reset to zero. The vehicle total odometer reading is retained.
How much does it cost to replace a TCM?
You can expect the parts costs to be around $450 to $700 while the labor costs will be around $50 to $200. Of course, you can order a new TCM online and ask a mechanic what their hourly labor rates are. However, most of the cost for this replacement job goes toward the parts cost itself and it can vary greatly by car manufacturer.
Is the ECM the same as the TCU?
The ECM is also sometimes referred to as the PCM (power-train control module), which consists of the engine control unit (ECU) and the transmission control unit (TCU). The ECM houses different codes, protocols and standard diagnoses for troubleshooting engine performance.
What should I do if my ECM goes bad?
It triggers a series of different codes to pinpoint the problem and restore optimal engine performance. However, when everything in the car seems fine, but your check engine light is still on, the issue might be a failing ECM. The mechanic will also look for problems in the wiring harness.
What is the ECM in a car called?
As the name suggests, ECM is all about engine performance and can help in the diagnosis of engine and transmission problems. The ECM is also sometimes referred to as the PCM (power-train control module), which consists of the engine control unit (ECU) and the transmission control unit (TCU).
What does the TCM do on a car?
Based on collected data, it sets the position of the camshafts, throttle; it sets up the ignition/injection timing. Both vehicles with automatic transmission and manual transmission are also equipped with a TCM (Transmission Control Module). This unit determines if the vehicle’s transmission needs to shift.
