Will my transmission work for Autocross?

[badseed6986]

First I just want to say I hope that I am posting in the correct section. If not, I apologize.

I have a 69 Camaro that is setup for drag racing. Now I want to go the pro-touring route and set it up for autocross.

There is going to be a lot of changes made and I think I know what I need to do except for one area, the trans.

It has a th400 with a reverse manual valve body and a trans brake. Would I be able to use this for autocross, or am I going to have to look into replacing it?



If the th400 wont work, how would a stock th350 hold up?

Thanks in advance for any help.
