I have a 99' AWD with 75k and i am starting to notice a slip from 1st to 2nd gear, all of the other shifts seem to be crisp. I know that the ECT snow mode starts the car in second gear. Can anyone think of any problems that may occur from leaving the car in snow mode continuously in order to avoid the 1st to 2nd shift?

Could you send me an Audio wiring diagram please? I want to see if i can tap a signal off of the the stock sub. gigantor7520@aim.com Thanks, Ryan
