Got the trans out and to the builder. He took it apart while we waited and my guess was right. The sprag came apart. He said it could have been alot worse. It only had a 12 roller stock sprag from TCI. Going to replace it with a 16 roller from A&A.

Well, that answers that question. I thought you said it had a sprag with extra rollers?

Yea that's what I thought it had. It makes a lot more sense now when my dad got the the one that turned to junk was half the price.

To help prevent this from happening again, never start your burnouts in 1st gear

That 16 roller unit is great and stops a lot of those problems

I like the look of the stepped, axle bolts used in Coan Super Sprag better than the ferrals on the A&A unit. But both should be a big improvement to the factory setup.

Well we know the effect.... now what was the cause?

When I had the trans in my old car updated, I inquired about changing from the stock sprag. The builder didn't seem to concerned with the "upgrade" as I had never had issues with it, and the stock unit was secure in the case. Springs were uniform and rollers true. I've always just done my burnout in 2nd which he said was just fine.

that is the 1 I used because of the stepped bolts.
