Trans brake?

On a stock trans,I would say yes.But only because the stock componets (bands,clutches,etc.) arent good for performane use.

I would look for a trans and have it rebuilt with performance rebuild kit,then put the trans brake on.You also should have a trans break compatable converter (one w/ balloning plates),and I would hook up a 2step.

Actualy,thats how my racing C4 is set up....:D
