If your BMW is showing warning lights or a system has stopped working, the transmission control module is a likely suspect. This guide explains what the part does, the signs of failure, how to choose the right OEM replacement and what to expect after fitting.
BMW electronics are tightly integrated, so the OEM part number and software level matter when replacing a module. We currently list 1 BMW transmission control module option from $37.04.
What the BMW Transmission Control Module does
The transmission control module manages gear shifts, shift timing and torque converter lock-up. When it fails, the related system can behave unpredictably or stop completely, so a correct OEM replacement restores original operation.
Signs your BMW transmission control module is failing
- Harsh or delayed shifts
- Gearbox stuck in one gear or limp mode
- Transmission warning light on the dash
- Jerking or slipping between gears
These symptoms can also come from wiring, sensors or a weak battery, so scan for fault codes before replacing the part.
How to choose the right BMW transmission control module
- Match the OEM number. Read the number on your original unit. The units we list use numbers such as 0260002642.
- Check the model and year. Our current BMW stock covers E39, E46.
- Confirm with your VIN. Use our VIN lookup or send us your VIN and we confirm fitment before shipping.
Installation, coding and programming
Most units need to be programmed or adapted to the gearbox and vehicle, so use a workshop with the right tool. Always disconnect the battery and follow the manufacturer procedure, or have a qualified technician fit the part.
