Really anyone can make one of these with enough time. A good 3 way valve will cost you a few hundred dollars. Take your valve body out. Pick what clutch you are going to activate to bind up the transmission. Then drill some holes in that channel that you can access. Then dam that channel and then source your feed pressure. You can do the valve as an external valve it has to be big enough to exhaust the clutch fast and your lines need to be big enough. This is a problem with these. Getting big enough lines in to dump the clutch fast. This is one of the main reasons I made an additional valve body to use a spool valve. Then get your lines through the pan and wiring or the case. Which ever you have room for and then raise line pressure enough that it does not slip. Etc. You could do this for probably 5-600.00 plus some machine shop work on the valve body for another couple hundred. And say 10hrs of work.
But that is not a product and requires understanding of the valve body and the clutches and which ones to use and like I said I am selling you a few additional products with the trans brake. A new valve body that has been modified and a B&M deep pan and you bolt it in like a new valve body. Wire it up to your trans brake controller. I buy a valve body, and a pan and machine a valve block and the valve and have a solenoid and machine the valve body, and pan sealed wiring through the pan and that all costs me a lot of money. I mean a lot. Like I said if I had the customers to make these in batches of 10-20 at a time I could save a lot but tying up 20k in product that I may never sell is not a good idea. And to be really honest I never thought I would sell more than one. I got commissioned to make it. Then a few people wanted me to make them for them so I did.
But this is not a t400 or a powerglide that basically has a spot in the valve body that you add a solenoid to and wala you have a trans brake and you have around 10k customers a year.
Have fun out there. Now that these are cheap there should be some race cars being made. I wish someone would gut one and cage it and start going really fast. If people can run low 10s in these as luxury barges then they should cut some real nice times if they were stripped of all the crap. I want to do the same with a v12tt car. Just ecu, tcu and a dash. One bucket and a proper drag setup. Cheap fast 9s car.

Joe,
I think I am following your build. Let me know when you are ready. I am going to need some lead time on the brake for sure.

I believe there are differences in the valve bodies/solinoids, I've seen/read folks that have put Mopar bodies in the MB version trans have had poor results.

Did you really pay 3K for a brake?
Where did you mount the button?
Wiring it: looking at the design, it was an internal solenoid.. I'm guessing internally grounded, what got power t the solenoid?
Did you actually pick up ET?

Is your car a racer car, or a something you drive regularly but race? It's more of a question about the suspension.. is it completely stock? Forgive.. I'm an mercedes noob, as far as what your car came with factory. What have you done to the car on that front?
Where you're at as far as ET/MPH goes if it's a street car.. I would imagine there's lots of compromises, and if it's a race car, depending on the class, if you're racing in one, you're giving up a lot there in order to drive it on the road.

2. I have a deutsch connector coming out of the ash tray where I plug in a hand-held momentary button on a couple feet of wire.
3. There are two wires coming through the side of the pan. One gets +12v and the other is switched to ground by the TCU.
4. No. The transbrake alone didn't help my ET. (but it did help my reaction times) The transbrake together with the higher stall took about .15s off my 60'.

What is it you're breaking? In the trans or other drivetrain parts?
