So the reset 'fixes' the cold shifting problem, if only for a week at a time? That sounds like a funky trans computer. If it was a sticking solenoid or something mechanical in the valve body, what difference would it make, resetting the trans computer?

My knowledge/experience with this car is not that great but this possible temperature-related electrical problem sounds like others I've seen in other cars/systems.

I guess the good news is, if the trans computer is dying a slow death, it will one day confirm its ill health by dying outright.
