TRAN'S BRAKE

I never used one either. It seems alot of people are going away from delay boxes here, so maybe you should just use a switch.
As far as safety goes you can probably buy a relay switch that won't re-activate for so many seconds. If not I could probably design one for you, it would be fairly easy.
The only other thing I have ever heard is stay about 500 rpms below the stall speed or the trans will get hot. I can't say for certain if that is accurate.

Pretty simple, but use a two-step to limit starting line RPM, like aready stated, under your total stall. Best procedure would be to light the last last yellow, then push the button. I always wait until the tree starts coming down before I hit the gas to the floor. Some like to light the yellows, and before the tree is activated, they floor it, but that makes you on the conv. a little long, building trans heat. Any other questions, just ask.

TRAN'S BRAKE
What about having to brake torque to about 2000 on the line before depressing button???? something about building pump pressure for full solenoid engagement???? btw this is going to be all T-C-I components. So if I understand write, you need to push button than put in reverse to back???? :roll:

·Transbrakes
Ed, mabe I can answer some of your questions
1.) What if I hit the button while in motion?-The transbrake works only in first gear.Also most brakes have a safety feature to help prevent you from putting the car in reverse down track. To apply reverse, you must have the trans in reverse & apply the transbrake button.
2.)What about having rpms to 2000?- You do need to have the engine above idle. Reason being is you need some line pressure to help lock the transbrake. You are locking the transmission between first & reverse. I am assuming that we are talking Powerglides here. I usually like to have at least 1500 rpms before applying the trans brake. I have had instances where I was below 1500 rpm & the brake didn't hold.
3.) Two steps & when to mat the gas?- I take it you are going to run a delay box & two step. Wire the trans brake through your delay box & low side of the two step. This allows you to put the gas pedal to the floor & set the RPM limit. When I run a .5 full tree, I put a 4000rpm chip in to leave the line. When I race a .4 Pro tree, I remove the low side chip & leave off of the convertor stall speed. I also don't mat the gas until my top bulb comes on when on the full tree. It keeps from building up heat in the convertor & transmission.On a Pro tree you mat the gas once both cars have lit the stage bulbs. The delay box allows you to leave off the top bulb on a full tree. You will be more consistant than trying to wait & leave off of the bottom bulb.
