Trans brake issues

[Canyon707]

The other evening I raced my car first run was normal. 2nd run after releasing my trans brake the car didnt move. I had thought I was not in gear. the next time same thing no forward motion after release. I thought it may be power short. I also now have no reverse manual. I have nothing the I also have a delay I looked at rewire seems ok but going to go through it again. Anyone have a trans brake fail? what did it do or not do?? Help......

I'm assuming no 1st gear or reverse? Low band is not holding. Stock low band servo piston? I'd look there first. The good news is that it can be fixed in the car. If it broke the ear off the band the trans has to come out.

Only issue I ever had was a switch on the wheel.
