Seems to me that other 'bolters have complained of water getting into their transmissions. I never found out how it was getting in there, but I believe it was only occurring with the SM420 gearbox. :confused: Hopefully, someone has solved this problem, and can provide some answers.

If water is freezing inside the trans, it may explain the morning lockup. Drain it.
