Trans brake Ford C6?

[56Ford]

Looking to buy a transbrake for a C6 behind a 390. Full roller C6 looking for some input on what one to buy. Thanks for your time!

I used to run the Ford Motorsport C6 transbrake valve body, which was actually made by Art Carr, and had his name on the casting. It held fine, but was slow releasing, especially on a 4 tenth Pro tree, and at times would roll ahead a bit when the button was pushed. On that valve body, the transbrake solenoid was actually a GM Turbo 400 kickdown solenoid bolted to the valve body, inside the pan.

Dave at Protrans in Lancaster, CA might have something.

Don't do it. Your waisting your money and the nightmares will began. I've ran all of them. The C-6 is not made for a brake. Put a brake on a C-4 or a GM tranny!!

What will happen to a C6 with a brake? My buddy @ work just had one put in his C6 it's for his 428 FE in his 69 Fairlane.

It should be fine, Greg. I ran my Art Carr transbraked C6 for many years, running 10.5ET`s s at 3200 lbs. The brake itself worked fine, and the trans was very reliable. The only knocks I had were that on a 4/10`s Pro Tree, it didn`t release as quickly as most other transmissions, and at times when you pushed the button, the car would roll foreward a couple of inches. I always found that if I quickly tapped the button a few times between the burnout box and the staging area, the "roll in" was eliminated. The relatively slow transbrake release was never an issue on a full tree. Of course, the C6 does eat up a fair bit of power, as do all automatics to some degree.

I ran a c6 brake in the early 90's. Used TCI, Art Carr, Hipster, and one other, but I can't think of it now, my brain wants to block that period in my drag racing career. I had multiple c6's built. Many well versed in the C6, but the nightmare was weekly. 2-3 flares, foreward clutches burnt in one pass, huge amounts of et lost from weekend to weekend.
Put it this way; 1973 Gran Torino Sport 4000lbs. super stock car with bracket set-up. Almost stone stock 460 c6 with brake struggled to run 11.98 et. After a change to a T400 w/ brake 11.48 et. No more dropping of pans, Type F all over me while trying to race, no more have to pull the r/side header every week to remove the trans. (Pieces of the cylinder head started to crack and break off!!)
Don't get me wrong, the c6 is a fine transmission in a truck, even a turbo boosted 7.3L diesel. And I had pretty good luck with just a manual valve body, it's just when I tried a brake is when the nightmares began. Just my .02

Well, your C6 experiance was certainly worse than mine. I ran my 428FE powered bracket racer Fairmont with a C6 from 1988 to about 2000. For the first few years I ran a basically stock C6 with a TCI reverse pattern manual valve body, and I decided to try NHRA Super Street in 1990, I went with the Art Carr transbrake valve body, along with the Ford Motorsport low drag needle bearing setup, with the lower first gear. (about 2.72 if I recall correctly). At that time, S/ST was a .400 Pro Tree, and 2500 lb minimum, to get any RT~s better than about a .480, I had to go to really short front tires, and even then, anything better than about a.430-440 was a guess. After 2 years of that self abuse, I just bracket raced the car, first in Pro, and later in SuperPro with a delay box. The transbrake C6 worked really well there, very consistant, and once I got the delay box dialed in,I won a lot of rounds, and several races at 3 different tracks. My C6 was built by a local MoPar racer who owned a transmission shop, and after the first 2 seasons , everthing inside still looked like new, so I left in in for 4 more years, and it still looked good. I did use the 428CJ R servo setup, and never experianced any flare up between shifts. And I didn`t baby it, every pass was WOT on the trans brake (5200RPM, it would go 4500 on the footbrake), it was dead reliable. The transbrake was almost a tenth quicker in 60 feet 1,40 to 1.48 foot braking. The only reason I ever sold the C6 was I was getting bored, a Jerico & a clutch pedal fixed that rather nicely.
