Pics of what happens to your transmission after a sudden driveline failure
So I finally got around to pulling the transmission after I broke the rear end yoke about a month or so ago. Just wanted to post up a pic of what damage it does to your tranny after you lose anything after the output shaft. Here's what I've learned from this experience, make the drivetrain as bullet proof as possible....to avoid this type of situation. Why is this posted in the FI Section? Because there are a few guys still running fairly factory/unfortified rear ends and suspension like myself. Just wanted to show the price that is paid when something fails in the drivetrain, as it WILL take out your transmission as well. This on the right is what came out of my transmission, on the left is what it SHOULD look like. And no, I didn't pull ANY rollers out for dramatic effect.... this is exactly how it came out.

Overrunning a drum is damn near a death warrant. It's like having a pipe bomb in your transmission tunnel.

I knew what you meant. I posted this to show guys that when you have a rear end, or driveshaft let go.....you just killed your transmission as well. It's not a case of just fixing what failed, but now you just destroyed your low roller clutch, along with what failed in the drivetrain. I guess what I'm saying is, when something breaks (driveshaft/ rear end).... make it standard practice to go through the transmission and replace the low roller clutch, as it's likely done for. Don't even try to drive it.

Does it only require a breakage, or could sudden traction loss give same sort of result ? Seems very fragile ?

Broken diff yoke? What diff?
In my experience most nasty failures are a result of bad suspension set up. Wheel hop causes a lot of carnage. I've also had stick shifts eat up a LOT more parts than autos. I cant recall seeing any threads where an auto failed and the driver got hurt ( im sure its happened though ) but Taner lost a toe iirc when his twin disk mcleod grenaded.
Anyways over built chassis is a formula I approve of for many reasons. Reliable fun is the biggest, safety is also high on that list. When sloppy first got going with all those boosted sbe's in junk cars they chucked an axle out of an LTD going down the road and put the car in the ditch. No one hurt but that could have been verrrrry bad.
At very least any of you guys building performance cars need to ditch C-clips and get bolt in axle retention. Most important thing for safety is keep the wheels under the car

Was at the track, and the prep was 2nd to none. Left around 1psi, was looking to skip 10s entirely and join the single digit club.... so I got greedy and didn't even try to ease it out before I matted it. Still on 10 bolt and rubber busted lca. You are very fortunate to not have killed your transmission.

I was a little kid when I was told... "when you build a car you start from the rear and work forward"
I just replaced all of my driveline parts with good stuff and did my entire rear suspension. I will add boost, fuel system, and a built trans next over this winter.

Video footage. If you pause at 0:43, you can see shims and various other rear end pieces from the car before me. 3 cars killed their rear end within 45 minutes......same lane. When my buddy helped me push it off the track he lost his shoe, track was killer that day....literally.
