Damaged trans?

I am, and you better pull the trans and inspect or replace the over running clutch in the rear of the trans. If it's damaged as will likely happen when breaking a driveline under power in 1st gear the next pass could end up with the trans exploding and injuring you, a bystander (I've seen pieces fly into the stands and injure spectators), and your car. Cheaper in the long run, paper and seal kits are cheap as are the race, roller and spring kits.
I couldn't agree more. As soon as I read the first post I was thinking sprag.
