If your Ford Focus suddenly starts banging into gear, refuses to shift, drops into limp mode, or acts like the transmission has forgotten what gear it wants, the transmission itself may not be the first part to blame. On DPS6 PowerShift-equipped Focus models, the Transmission Control Module (TCM) is a well-known failure point.
One common replacement is the A2C53377498 / A2C30743100 TCM, cross-referenced with Ford service part AE8Z-7Z369-F. Before ordering one, however, there are a few fitment and programming details worth knowing.
Common Ford Focus TCM Failure Symptoms
Ford service documentation for DPS6-equipped Focus vehicles describes TCM electrical failures that can cause intermittent loss of transmission engagement, no-start conditions, lack of power and an illuminated check-engine light. In the workshop, the symptoms buyers notice first are usually more everyday:
- Harsh, delayed or unpredictable shifting
- Transmission stuck in one gear or limp mode
- Car will not engage Drive or Reverse normally
- Check-engine or transmission warning light
- Clutch actuator-related trouble codes such as P0902 or P090C
- Loss of communication with the transmission controller
That does not mean every shuddering Focus needs a TCM. The DPS6 also has clutches, actuator motors, wiring and sensors that can create similar symptoms. A scan for transmission DTCs should come before parts-swapping.
Fitment: Check the Transmission, Not Just the Model Year
For U.S.-market cars, the safest core application is the 2012–2018 Ford Focus 2.0L equipped with the DPS6 six-speed dual-clutch automatic transmission. Ford part number AE8Z-7Z369-F is an official TCM service number used for Focus/Fiesta applications.
Australian Focus fitment needs extra care. Earlier LW-series cars used the PowerShift dual-clutch transmission, while the 2015 LZ update moved to a conventional six-speed automatic. Australian buyers should therefore verify the VIN, transmission type and the number printed on the original module instead of ordering by year alone.

Why a Pre-Programmed TCM Can Save Trouble
The UCarPart module is sold with Ford Focus 2.0L software already installed. That addresses one of the biggest complaints found in public marketplace reviews: buyers receiving a physically correct module that is blank, has the wrong strategy, or is not recognized by the car.
Still, “pre-programmed” should not be read as “every car needs zero setup.” Public owner reviews show both outcomes. Some cars shift normally immediately after installation, while others still need a clutch adaptive learn or scan-tool procedure before the DPS6 behaves correctly. If your technician uses Ford IDS or FORScan, plan for that possibility rather than treating it as a failed part.
What Owners Commonly Wish They Knew First
- Match the original number. A Focus badge and 2.0L engine alone are not enough.
- Do not diagnose by shudder alone. Worn clutches can shudder even when the TCM is healthy.
- Check battery voltage and grounds. Low voltage and poor connections can create communication faults and make programming unreliable.
- Do not ignore speed-sensor codes. If codes such as P0722 or P0723 remain, inspect the related sensor circuit and wiring instead of immediately replacing another TCM.
- Expect relearning. The car may need clutch or transmission adaptive learning after the module is installed.
Is the A2C53377498 TCM the Right Fix?
If your Focus has the correct DPS6 transmission, the original module matches one of the numbers above, and diagnosis points to a failed TCM, a pre-programmed replacement can be a much simpler route than sourcing a random used module and then trying to make its calibration match your car.
For buyers in the U.S. or Australia, the best approach is simple: check the old module number, confirm the transmission, and use the VIN when fitment is uncertain. That extra two minutes can prevent the most expensive kind of repair—the one that replaces the wrong part.
Quick FAQ
Does A2C53377498 replace AE8Z-7Z369-F?
They are commonly cross-referenced for DPS6 TCM applications, along with A2C30743100 and A2C30743102. Always confirm against the original module and VIN.
Does a programmed Ford Focus TCM still need relearning?
Sometimes. The base software may already be loaded, but a clutch adaptive learn or another scan-tool procedure can still be required after installation.
