NO! We don't have a two step and she launches at 4000 rpms on the transbrake, where it is designed to launch from.

There is a way to setup a two step using the stock pcm. I believe there's a way to setup a N and Drive limiter. I've not looked into it but theory you can wire up the neutral/park wire to the trans brake, thus when you lanuch it goes back to drive limiter settings as well as launching the transmission

Nope wont hurt it, the 2 step will just make it more consistant. Just dont stay on the brake too long, If I remember correctly when you are on the brake (giving it gas of course) it heats the fluid around 30-50 degree's per second

an other issue with a trans brake is high line pressure. lf the trans builder used iron sealing rings, high line pressure wears the grooves. if on the other hand he used plastic type they live better. good luck

couldnt you get a vacuum modulator for that??

john kilgore

l have built trans brakes with internal solinoids and that would let you use a vac mod, but l have never had a vm on them. internal solinoids to fudge the rules against tb's

More like 150-200 degrees/second. You dont want to be on the brake more than 2-3 seconds or bye bye tranny
