It sounds like he knows what is going on (using Winter mode to bypass first AND second gear), and is using Winter mode to get forward motion. I did the same thing when my transmission went at @ 113,000 miles. Winter mode allowed me to get the VX to the dealer for repairs. However, my check trans light came on... did yours?

Good luck getting your VX fixed, and if the bulb is out on your check trans light... have the place you bought it from pay!
