RE: HELP!! Can rainwater from a left-open sunroof damage my tranny?
Hi, Jesu, and welcome to the forum.
You aren't going to like this response, but there are some very sensitive electronics in the center console, and when they get wet, they typically short out and must be replaced. These electronics affect not only the windows, but also airbags (if equipped) and, as you've experienced, the transmission. From what I hear it's an expensive repair, in the 1K range. Since apparently a small spill of coffee can have that effect (great placement on the cupholders, MBZ), I would imagine heavy rains pouring down on it would do that, too.
If this was truly unavoidable (i.e., breakdown, accident,etc.), it might be worth reviewing your insurance policy and see if it might somehow be covered as ensuing damage.
Best advice I can give you is to call an indie (at least that will be cheaper than the dealer) and go from there.
Good luck and enjoy the ride,
