Wrecked the car today! **DIAG, PICS**

Wrecked the car today! **DIAG, PICS** - 05/22/11 08:49 AM

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!

I hate to hear about it bro, but the damage seems minor for what it could have been....especially when a drag car gets perpendicular to the track. Maybe a good excuse to finally go with fiberglass fenders? I will be curious to hear what the root cause was. From what you describe, sounds like the transmission. I know you will have it back out soon. Call me if I can do anything for you.

Didn't look too bad for the wild ride it went on. I kinda got the willies on my next run when I saw the black tracks go from the left lane around 1/2 turn and into the right wall.

It didn't slow Lonnie down much, I saw him Sunday driving 3 different cars.

Re: Wrecked the car today! **Diag** Pics - 05/29/11 05:00 AM

Well, progress has been made. Yesterday I managed to get converter out of car to get to Jason Brock at quickdraw to check it over for damage and install a new ring gear. This morning I started my day a 6 AM and drove the 75 miles to Kilbuck(BFE) to have the converter looked at. Jason cut it open on the spot and we saw perfect components and no internal damage. Off to Norwalk for my new Hoosier 32x14's to replace the flat spotted tires (75 more miles) Tires replace and headed to Dads to work on car. (60 more miles) Made it to his house at 12:30. Removed differential cover and inspected ring and pinion. Everything looked brand new, removed wilwoods and pulled axels. No twists in splines and axels looked like new. While disassembling I noticed that the rotors and pads looked very coarse and grooved. Decided car would not go back together with these components not replaced. Drove to Jegs and back (100 more miles) and replaced the rotors and pads in rear. 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. After getting the back end back on the ground I started to line up the replacement fender for front end. Fender is generally mocked up and ready to install Dzus tabs. I need to align the front fenders a bit as the structure is bent about a 1/4" to the right and the hood does not fit quite square just yet. I ran out of time to get more work done tonight as i had to get home(45 more miles). A long day closes and a little relief in finding a failed component. Not quite sure what caused the brake to lock, but kinda figure if it was electrical I shoulda seen the brake release after the delay in the box ran out. Does anyone know if the Tranzact pro brake is even capable of elecrically engaging the transbrake when in high gear?

Sounds like you may have found it but I'm stumped as to why the brake would have engaged.

Re: Wrecked the car today! **Diag** Pics - 05/29/11 01:19 PM

Thats a tuff one,Lonnie...Can you guys test everything to see if a short somewhere may have caused the brake to engage? That would have scared the hell out of me!!
Posted By: rowin4

Re: Wrecked the car today! **Diag** Pics - 05/29/11 03:28 PM

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.

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

Posted By: 440Jim

Re: Wrecked the car today! **Diag** Pics - 05/29/11 05:27 PM

Lonnie, is that a 904 or 727, front or rear drum and band burned up?

Mike, does the TA brake go into reverse with the gear selector in both R and N ?
Just trying to figure out what passage is tapped for the pressure and what it engages in each selector position.
Interesting thought about something broke and wedged the linkage (band?).

Anyone else with other brands?
Posted By: WILD BILL

Re: Wrecked the car today! **Diag** Pics - 05/29/11 05:36 PM

Jim, the TA brake uses the gear selector for reverse. No need to push the button.

I never tried the button in N to see what would happen though.

Too late Brian, he already has it Its a good thing when you find a component that has caused the problem instead of chasing ghost issues. Hope you get it all back together and remedy any electrical gremlins that might have helped cause this!!

Re: Wrecked the car today! **Diag** Pics - 05/30/11 04:21 AM

I'm not familiar with all trans brake valve bodies but I'm fairly certain that they all apply the front clutch as the locking member. When the car is staged and the shifter is in low, (LBA apply in this case) the rear clutch is on as well as the rear band. When the trans brake is applied it engages the front clutch which locks the whole trans up. When the button is released, the front clutch releases and you launch in low. In high gear, the front clutch is applied as well as the rear clutch, so engaging the t-brake button in high should do nothing as the front clutch is already on. I would look in the rear servo area for an issue. If the rear band applied in high, this would lock the trans up and the band and drum are pretty beat up by the pictures.
Posted By: Guitar Jones

Re: Wrecked the car today! **Diag** Pics - 05/30/11 04:36 AM

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.
Posted By: PC-CHARGER

Re: Wrecked the car today! **Diag** Pics - 05/30/11 04:42 AM

Depending on the valve body, you may or may not need the rear band applied. The rear band and the sprag clutch hold the rear planetary and either or both can be used along with the rear clutch to get low gear. LBA valve bodies use the rear band while non LBA valve bodies use the sprag. Adding a third member into the mix (the front clutch)locks the whole assembly thus the brake action.
Posted By: Guitar Jones

Re: Wrecked the car today! **Diag** Pics - 05/30/11 04:50 AM

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.

Re: Wrecked the car today! **Diag** Pics - 05/30/11 02:09 PM

You're correct. The valve bodies that do not have low band apply must not have a trans brake. So that would indicate that all trans brake valve bodies that utilize the front clutch to activate the trans brake are also low band apply units. I never realized this until you mentioned the two clutches applied. Thanks

As for the brake applying the front clutch and the rear band, are you sure of this or does the brake simply apply the front clutch and the band is applied through the manual valve movement? I guess an easy way to check would be to have the trans in neutral and push the brake button. If the car backs up, then it would indicate that the brake applies both but if is does nothing, then it would only be applying the front clutch, correct?

Mine(non low band apply)wont do anything if in neutral
and hitting the button.... T/A manual reverse pattern
Posted By: PC-CHARGER

Re: Wrecked the car today! **Diag** Pics - 05/30/11 02:44 PM

Thanks Mike, but this raises yet another question. You say yours is a non LBA valve body with a brake, yet what Stephen pointed out is that if you don't have the band on and you press the brake button with the manual lever in a forward postion, you basically have high gear since the sprag does not hold when both clutches are applied. I believe he is correct but if your valve body is indeed a non LBA with a brake, then I'm not sure what to assume. I thought the T/A units utilized the front clutch as the holding member but maybe not?

My T/A brake does nothing in neutral, as I said it's claimed to have a timed rear band release. After the front clutch is released the rear band can be released anytime before the 1-2 shift. My VB has no 1st gear braking so the valvebody is not applying the rear band, the brake portion is doing it. As I said though I've never really studied it to see how it works, as long as it worked I just wasn't that curious. This episode though has me thinking.

Thanks Mike, but this raises yet another question. You say yours is a non LBA valve body with a brake, yet what Stephen pointed out is that if you don't have the band on and you press the brake button with the manual lever in a forward postion, you basically have high gear since the sprag does not hold when both clutches are applied. I believe he is correct but if your valve body is indeed a non LBA with a brake, then I'm not sure what to assume. I thought the T/A units utilized the front clutch as the holding member but maybe not?




In mine you have to have the shifter in low gear for
the brake to work and when you manually have the shifter
in low you are applying the low band if I'm not mistaken

Just thinking out loud, but never having a T/B in a Mopar trans (just the glide)....is there a pro-brake & non-pro-brake offering for Mopars...????

Asking because in the glide....you only need the button for reverse with a pro-brake

Sorta... there is a low band apply and a non low
band apply... I run the non low band apply and you
dont need the button BUT to my understanding the low
band apply version you need to hit the button for
reverse... they offer a faster release version also
for the pro tree

There are many different manufacturers offering different valve bodies. The T/A was one of the first to use an internal solenoid release. Early Lamb versions had an external solenoid and didn't work all that well. Supposedly the T/A VB that I have, an early version, is not good for a pro tree. I can however cut .4teen lights with it if I don't use a two step. Otherwise it's a .500 tree brake.

Since then there are many others with various features, Griner, JW, TranzAct, Hipster, TCI and so on.

More differences in the makes, models and applications than I had thought. Thanks for all the input. Always learning something here.

BTW the brake I'd like to have would be the clean neutral VB. The shift pattern is P, R/N, (push button for reverse) 1, 2, 3, N. Since I use an automated shifter I'd have to modify that as well as spend the $700 for the V/B. That's not going to happen unless I win the Lottery.

Mike I had a griner NON LBA TB, and I had to use the button for reverse. Don
