Anyone ever seen a failure like this? I tore my trans out this weekend to send it in for a rebuild and this is what I found when inspecting it. The countershaft is missing about 5 teeth and 2 are chipped off the input shaft from that failure. Nothing else in the trans is in bad shape - no other gears and none of the bearings are damaged - the fluid was still perfect in color and had barely any metal in it. The magnet caught EVERYTHING. I only drove it about 15 miles after it failed, so that saved it from having crap running though it. The car has 150K on it, but I can't be sure the trans is original, so I'm not sure if that's a factor in the failure. I doubt I'm even pushing 400RWHP, so it's definitely not power that killed it. Any ideas?

I don't really know the history of the car before I bought it. During the time I've had it, I've drag raced it quite a few times, but never did any hard clutch dumps. I also have never missed a gear. The failure really didn't happen all at once either. I started feeling something through my shifter under deceleration for about a week - the shifter was kind of moving around a bit, and then one day I downshifted and when I let the clutch out, it started making noise. There was nothing violent about it either, it was just a downshift to slow down and turn a corner. Beats me why it did it.

I was in 2nd heating up the tires at the track once and the track official ran out and told me to stop like i ran someone over.
I freaked out and stalled it.
It made some weird noises the next three passes and two weeks of driving.
I took it apart to find two teeth broke off the input.
The trans was a BW ST10. I got new parts to rebuild it, ran it for a while and sold it.
The guy that bought it broke second with a stock 305. The whole trans was shock loaded so theres no telling what all was effected by that until it broke again.
