rdsk8ter Posted January 26, 2007 Share Posted January 26, 2007 I am very confused asking for a hand here. I am building a turbo 400 tranny and need to decide if I am going to put in a trans brake. plus sides way better launches manual shifting not to hard on the tranny no way to hit nuetral (reverse pattern) negitives manual shifting having to shift all the time more money Please if you have any oppinions about this i would greatly appreciate it. Background on the car. Its a weekend warrior that is still being built. lots of time and thought have gone into this build and i want to make it unique in its own way. You guys and gals always give me great advice and I thank you for the help Quote Link to comment Share on other sites More sharing options...
nscason Posted January 26, 2007 Share Posted January 26, 2007 I'm no where close to an expert, but i have always liked having complete control of the car. if you don't mind the shifting all the time i would go with the trans brake. i don't really know much about automatic tyranny's though. my dads 71 jeepster has a turbo 400 and OMG that thing just about snaps your neck every time it shifts and I LOVE THE FEEL. all that power on tap. i have known other people that don't like to think much or multitask when driving. there's my 2 cents worth. hope i helped.

jakeshoe Posted January 26, 2007 Share Posted January 26, 2007 I have a TH400 transbrake setup that is a manual/auto valve body, so it shifts itself as normal but you can also have the transbrake. It is not reverse pattern though. Quote Link to comment Share on other sites More sharing options...
jnjdragracing Posted January 26, 2007 Share Posted January 26, 2007 A Transbrake is a nice feature to have. It also really depends what you are planning on putting it in? If you are thinking about putting it in a Datsun Z with a stock suspension / IRS, then I would not do it. You will break it. We normally run a powerglide 2 speed with a transbrake in the other race car, if it is light use a glide, heavy use a turbo 350 or 400. This is normally the general rule. We have tried to use the turb 350 in our Z-car and it was way to violent, tuff on parts. IMO.... John Quote Link to comment Share on other sites More sharing options...
dr_hunt Posted January 26, 2007 Share Posted January 26, 2007 Any time you put an auto trans in two gears at the same time, it's going to be hard on the trans and converter since it keeps it at stall speed for a few seconds. If you use one try to stall it for the shortest time possible before releasing. Sometimes you see guys up on the stall or 2 step as soon as they stage and before the tree falls, which is not a good idea if you want it to last. The driveline is not loaded like in footbraking. I run the transbrake and the launch on footbrake gives me better 60' times and launches harder, which is probably due to converter design. I can cut a better light on the transbrake since it requires less movement. Quote Link to comment Share on other sites More sharing options...
dalesince59 Posted January 27, 2007 Share Posted January 27, 2007 A transbrake is not a good choice for a street driven car. You can still purchase a full manual, reverse shift pattern valve body for the turbo without the transbrake option. Quote Link to comment Share on other sites More sharing options...
