I guess so!

When a high performance manual trans fails can/does this kind of thing ever happen, meaning the catastrophic damage where it explodes and catches fire sending shrapnel in in all directions?

I don't think I've seen that, or this with an automatic or dual-clutch either. This sort of incident on a dyno has always been motor failure as far as I recall... I've seen a lot of those videos.

It can happen if the case breaks. Normally wou will wipe the teeth or cut clean one of the shafts.
It is more rare to have a failure like that but it can still happen.

Autos in case of shifting failure can engage wrong gears or several at the same time and lock up. In a manual that's way harder to do.

Thanks for the info, makes me feel a little safer at 130 mph in turns like 8-9 at Willow Springs. A failure like this could disastrous but my ZLE is not modded so that helps too.

Andrew was getting ready to take his ZL1 to some show in Kentucky (cannot remember if it is LS fest or Camarofest). They put it on the dyno and on the second run the A10 grenaded...

I honestly thought the A10 was more robust than that. He only makes 829hp to the wheels.

Here is a link:

I saw a video of this happening on a built Camaro Vert, the trans exploded on the burn out, the trans didn't like being shifted into third when the car started to hook on the burnout the trans exploded and the gal driving had to be pulled out of the car and one of our members helped her get out while the car was still on fire. It was a bad deal.

I can't think of a single time I have seen or heard of a Tremec manual coming apart.

I have heard of broken shift forks and gears breaking, but nothing this serious.

Has someone seen a tremec blow up like this? If so, send me a link. Just curious...

It had a cam, maggie and all the supporting mods. And went 9s I believe on a tire. Then he sold it. Then bought it back and thats what you seen now.

I’d bet I know the dude better than most. Wonder why he had to buy it back…

Yes but also, downshifting bad or missing a shift can take you out of the track.
Like 5th to 2nd you can lock up the rear tires and spin out.

I had pressure plates rivets breaking while shifting at 6k rpm. Did 4 clutches until I got a race clutch with no dampening at all to fix the issue.

They both have pros and cons. Autos seems to explode under weird shifting scenarios. Burnouts and dynos. Both scenarios trick the computer at some point.

I keep the trans in first or second, manual mode when doing a burnout and never let it shift, for this exact reason.

Hopefully, that's why they added Line Lock into 2019+ (gonna be a nice send-off for these tires when they're low enough )

Glad to see that no one was hurt. Things could have been real bad.

While I don't have any on video, yes Manual Transmissions can come apart / explode as well. The gear oil is much less likely to catch on fire than the ATF.

I don't believe anyone should have worries about road racing close to stock ZL1s.

We have experienced two cracked transmission cases in road race applications (fast tracks) one Tremec and one 10L90. This was due to aftermarket driveshaft harmonics.

Yes no doubt, I was tracking an idiot proof DCT for 6 years before getting my 2018 ZLE and I am not a great shifter. It took me a couple of years to stop occasionally mis-shifting into too low gear but I somehow always managed to catch it and avoid over-rev... I love the M6 it's made me a better driver, but I won't be surprised if I do this and break the motor. I'm better off with an idiot proof trans, I know it's a great A10 and faster laps, but I don't love 10 speeds that make paddle shifting obsolete. Would prefer a 6-8 speed DCT.

Line lock is in all ZL1 2017+
