So I got my '94 TA up and running and decided to take it to a local auto cross to get some seat time. The car happens to have a 4L60E automatic trans. I never autocrossed with an automatic before but figured it wouldn't be a big deal. There is one less pedal after all. Boy was I wrong. First of all the shifter only goes down to "2" on this car. There's no option to lock it into first gear which would have been ideal because it was a small course. Secondly, by leaving it in any of the other gear settings it has a nasty habit of downshifting into first about half way through my corner exit and making me go into massive oversteer. I figured it would have stayed in the gear I selected ie 2nd.

My question is this: What can I do to either lock the car into a gear or be able to shift into first on demand with the shifter to add predictability? Any advice would be appreciated.
