I have a true street car with a TH350 (2.73's to make it livable) and a turbo 363 cid LT4. I currently am using a 2-step to build boost on the line, but anything over 2000 rpm and ~2 psi and it pushes through the brakes. I need a trans-brake to get the 15 psi I need to pull a good 60', however, all the trans-brakes I can find (TCI, Hughes, etc) only offer them in manual valve-bodies with reverse shift patterns. To keep the car 100% streetable, I want it to be fully auto with the normal shift pattern.

Where can I get a trans-brake like that???

Thanks,
Mike

 

As far as I know.......you can,t.
Why do you want to keep the automatic shift? A manual valve body is alot of fun and you can actually have a reason for having a monster tach with shiftlite.

I have a TH400 with a reverse manual valve body, it has a transbrake but I have not hooked it up yet to keep me from being tempted on a 10 bolt rear.

I LOVE this tranny, its the new "best mod I ever did"

 

As I said, this is a true street car, not a race car. I don't want a manual valve body because it has an automatic transmission. There's a reason the OEM's don't sell cars with manual valve bodies. I don't have a monster tach and a shift light either, nor do I want them. I want the car as quiet as possible, power windows, cruise, ABS, A/C, even the stock hood because cowls reduce visibility. My roll cage has removable door bars and I take them and the racing harness out as soon as I get home from the track. Get the idea?

They sell trans-brakes for AOD's and 4R70 Ford transmissions with conventional shift patterns but I can't get one for a 50 year old TH350???

Now your talking semantics, what you call a "true street car" I call a race car. With your mods and the fact you have given up overdrive I did not think you would get so bunged up over shifting for yourself.

Its your car so Good Luck with it.

 

Did you miss the part where I have 2.73 gears???

Just a few weeks back, I let my 60 year old mother borrow the car for a week. You get in it, turn the key, put it in gear, and go. Gas up with 93. No special instructions, everything works just like her bone stock 2002 T/A. All that and it pulls over 140 in the quarter. With a full-manual reverse-shift pattern, I would not have been able to let her borrow it. That's the way a street car should be.
