Mini Roadster Automatic Transmission Issues

That sounds remarkably similar to an issue I experienced with my Mini Roadster. I recall the check engine light and transmission indicator illuminating in conjunction with some rather unsettling slippage during gear changes. Grinding noises are never a good sign; clearly something amiss within the automatic gearbox. Have you had the fault codes read? Knowing the specific codes could offer more insight into the converter fault.

Yes, I've read the fault codes; it points towards the torque converter lock-up clutch being defective. Your description is spot on. I am just curious, did your error code specifically mention the converter, or was it more generic? Were there any other symptoms I may have missed?

Yes, the error code did indeed point directly to the converter lock-up clutch. As for other symptoms, I would describe it as occasional 'shuddering' at certain speeds, almost like driving over rumble strips. I strongly suggest getting a professional assessment at a workshop. It is likely a converter fault.

Right, the Roadster's back and running. Confirmed converter fault as suspected, got it replaced. Bill came to 2120€. Thanks for your input, much appreciated. Hopefully, this thread will help others with similar auto transmission problems.
