Software updates are usually to improve an existing system, not to 'fix' serious issues like going into limp mode.

I would be asking what the fault was the update was meant to fix,
i.e. what was not working with respect to the the gearbox at the time the error code was logged.


The car is almost certainly not going into limp mode due to a transmission problem
without logging a fault code.


Put it this way:


If the car is going into limp mode without logging a fault code, I'd want my money back so to speak.
