About ECU Transmission Control Units

The BMW ECU transmission control unit is an on-board computer which electronically controls the transmission of the vehicle. TCUs can be separate from, or in this case, attached to the ECU. The BMW ECU Transmission Control unit contacts sensors that are placed around the vehicle to receive data in order to accurately calculate when to change gears and which gear to use as well as improve fuel economy and drive quality.

These sensors include the vehicle speed sensor, the wheel speed sensor, the throttle position sensor, the turbine speed sensor and the transmission fluid sensor. The TCU also uses data sent from the ECU. This controls and maintains the efficient running of the engine as well as scanning for any abnormalities in its function.

If a BMW ECU transmission control unit begins to fail, you may notice a loss of power, error message or difficulty in changing gears. This problem can be intermittent at first, and can sometimes be rectified temporarily by turning off your car and turning it back on again after a short while. Ultimately though, any damage to a BMW ECU transmission control unit will need to be repaired to correct the fault.

BMW trivia

• Pop Art legend Andy Warhol was asked to hand paint a BMW, and he did the whole thing on a full-sized model in 24 minutes. He said afterwards, "I adore the car, it's much better than a work of art."
• Did you know that BMW built a Lamborghini? The two popular companies decided to make a race car together, but Lamborghini pulled out during the manufacturing process. BMW carried on, and the final result was the original BMW M1 supercar.
• The main headquarters for BMW in Munich is designed and shaped to look like car parts. There was a whole new 'four-cylinder' building added on in 1973, and there's definitely the look of an engine about the architecture.
• Electric cars might be all the rage now, but BMW built their first one in 1972 and called it the BMW 1602e. It didn't quite make it to market though, thanks to the fact that it could only hold a twenty-minute charge.
• The BMW 3.0CSL was sold in the 70s and had the unusual addition of a spoiler that was kept in the boot. The owner could install it if they wanted to, but BMW couldn't sell the car with the spoiler attached because of road laws!
