that is the question. Can somebody please explain to me exactly what a transbrake does and how it is hooked up in the car? I am having the tranny built for my racecar, and I can't decide if I want to go with a regular full manual reverse pattern valve body, or one with a transbrake. If I go with the transbrake, I would not have to use it everytime if I did not want to, right? If you don't activate the trasbrake, the valve body would work just like a full manual, right? What would the advantages be for each one? The car is strictly a drag car, so street drivability is not a concern.

since it is a STRICLY drag race only i would.....its just a differ valve body and no u dont have to use it everytime......u pull up on the line and press the button and its on and then u rev ur car at what ever u launch at then press the button and hold it and when it hits green let off and ur gone...... thats about it mostly graemlins/clonk.gif graemlins/beers.gif

Hey Dude,

A transbrake consists of an altered valve body and solenoid. When the solenoid is enaged (apply 12v) the valve body will open up the fluid passages so that both the reverse and 1st gear bad/clutches are applied at the same time. Essentially the car is in reverse and 1st gear at the same time. Having a transbrake will not affect streetability one way or the other, IMO. However, having and using a transbrake with any freqeuncy will likely affect the longevity of the transmission (time between rebuilds) and possibly other drivetrain parts. I have a brake on my TH400 and have used it a couple of times playing around. The launch is so violent I can't hold it in 1st gear (reverse valve body with TB button on the shifter). If you decide to install a brake I recommend mounting the switch on your steering wheel or otherwise away from the shifter.

HTH.

What trans?

Trans is a turbo 400..

Dude;

If you get the "Pro-Brake", you will have to hold the button down to back-up, or install a by-pass switch. It releases a little quicker, but a pain if you need to do any backing.

Good luck with what ever you decide.
