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.

yes, there is a rubber tab on the shifter track that keeps it from going into 1st. i think you can get to it by taking just the upper console piece off and using a utility knife , just cut it out ( i have done this before, but it's been a few years and i'm gettin older.. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/rolleyes.gif) ). on the LTcars this does mean you have 2.73s out back (GU2 code or something like that).

if you wanna spend some $$ but not building a full on race trans, TCI used to make a plug-n-play "brain" for the 4L60/65/80E that came with paddle shifters that mounted on the hub column, behind the steering wheel. when turned on, you controlled the trans completely with the paddles, i.e. will stay in the gear you last selected. IIRC it was about $6-700 (again, i could be way off here, so please forgive me)

or...you could do a T56 swap...it's not as bad as it sounds....but it's quite a bit more time and $$
