Before a wildfire spreads and anyone wonders about the facts. My Saturday morning time run at the Mo-Power classic event ended in disaster. After making what I thought was an outstanding run thru the 1/4 mile 9.57@ 138.17(New best MPH), after I lifted at the stripe and went for the brakes my car went into what I would describe as engine braking(jake brake) and began to decelerate hard, had enough time to look to see oil pressure good and then rear tire lock up @ approx 90mph car was briefly perpendicular to the retaining wall before it rotated a little more and left front into wall bouncing left rear into wall. Left front fender is a loss and quarter gonna need extensive work, but did not strike the wheels and all frame work okay, did not even bounce me around in the seat. I am sure there are some that took pictures, and it is okay to post them, but long story short I am just fine, now need to find out the root cause. Suspect trans failure of some sort and there was trans fluid leaking after I came to a stop. Thanks to everyone that checked on me, and I WILL BE BACK!
Sorry to hear you kissed the wall, and I see here on Moparts that you have gotten 39 man hugs but no one asking if they can help you out. I always help out my customers when they crash my fiberglass parts. Give me a call here at Sled City Fiberglass 1-614-875-0369
Thanks Larry, you will probably hear from me soon, I was planning a furthur inspection of the car up at my Dads to see what I may be able to get away with still.

It was great seeing ya today
Sounds like you may have found it but I'm stumped as to why the brake would have engaged.

A guy that builds race transmissions once told me that certain trans brakes can lock up because of a grounding problem, can't remember what brand he was changing out because of that though.
it's ok to butt heads, just don't do it with a butthead

While I was gone Dad tore down the transmission for autopsy. That is where the following was found.
It would appear as though the transbrake engaged causing the trans to lock up.
Holy cow! That sounds like a nightmare come to life. Scary
We need a discussion of what goes on when the transbrake button is pushed in relation to the gear selector position, etc. The basics should be the same for all TF transbrakes, but the details of how they do it (tap the pressure) may be different.
Now why the solenoid engaged is another issue.

Not being a tranny guru but to my understanding it SHOULD NOT have done anything... he was in high gear and in my trans it ONLY works in low gear... I have hit the button when in second and high just to see if anything would happen.... nothing happened... (in the pits) mine is a T/A manual reverse NO low band apply... I am wondering if a chunk of metal broke free from something else and got wedged in the band/drum area then its a welding process due to friction

The rear band must also be applied along with the front clutch for the trans brake to work. Otherwise you'd just have high gear. My T/A brake says it has a timed release of the rear band. How it works though I don't know as I've never really looked into it in depth to see how the fluid is routed through the valve body.

If you have the front and rear clutches applied you have high gear, the over running clutch (sprag) will not hold, you must have the rear band and front clutch applied and the rear clutch released for reverse. Keeping the rear clutch applied is what locks it.
Granted you don't need rear band apply for 1st gear but you must have it for reverse. So the brake must apply the rear band and the front clutch while the rear clutch is engaged.
