transbrake

Is there such a thing as a non-reverse pattern, non-manual transbrake? Everything I have seen is a reverse pattern full manual unit which I want neither. I have my transmission setup to shift at the proper rpm so I do not want the manual functionality nor the reverse pattern. Thanks.

It's a TH350 rebuilt with shift kit less than 2000 miles ago. Another question...are there any brakes available that allow engine braking and don't require the button to be pushed and held to backup? The engine braking is my biggest issue. Thanks.

I've never seen a trans brake tranny that functions in automatic shift mode. transbrakes are used for racing , drag racing , monster trucks, sand drags.

Even though I have been in the performance tranny biz for many years , I am sure I have not seen it all.

Chazmac on this board is widely known/respected in the performance tranny industry, perhaps he will chime in or send him a PM on this question

From the reading I have done I am 99.99% certain that a transbrake will not function in automatic mode. My question now is...are there any transbrakes that will allow engine braking and don't require the button to be pushing and held to backup? Also, I'm going to install a ratchet shifter either way so the reverse pattern is no problem either.

I have seen systems that allow reverse by the trans being in neutral and pushing the button or by selecting reverse and not pushing the button. Just to clarify what do you mean by "engine braking"? Do you mean like on compression or the braking function as in transbrake locking the trans.

By engine braking I referring to the deceleration effects the engine has on the car. For example, at the end of the 1/4 mile you leave your car in gear and the energy required to rotate the piston through the compression cycle essentially slows the car down, versus putting the car in neutral and coasting. The transbrakes I have seen so far say "no engine braking" which I am taking as once you are off the throttle you will essentially be coasting. Take a look at the instructions to this TCI transbrake for a TH350 and note the first line.

I have only been inside a t400 so can't really say about the 350 but from a quick look at that particular TCI setup, in step 10 they remove the front band and there is a good chance that is why no engine braking. I don't think all manufacturers are the same.

I have a trans king trans brake in my drag car with a 350 turbo.It will engine brake fine. I don't think a trans brake is a safe thing in any street car.Keep in mind you need a special converter for a trans brake tranny. They run hot when on the brake so you need a temp gauge and you must release brake when trans get hot or fry your trans.If for any reason the brake is applied when car is in motion it's instant disaster

anti balloon plates are recommended on the torque converter with trans brake use

My converter has a 3600 stall with anti balloon plates. I understand the risk of running a transbrake on the street but I'm just tired of trying to footbrake it at the track. Don't the newer transbrakes have a lockout feature that will not apply the brake if the button is accidentally pressed in 2nd or 3rd. That would only make sense as no one I know of launches in any thing but 1st.

I would suggest you call some companies that sell a transbrake v-body you are interested in for the operation explanation of the unit.

You are correct many of them do not allow activation of the trans brake in 2 & 3 gears.

Call and ask questions
