I wonder how long that sprag had been hurt, or if he did the damage on the first burnout in 1st gear where it seemed like he pedaled it and also shifted to second.

That's my worst nightmare with a non-LBA valve body. I don't do first gear burnouts but it still worries me.

Can a non-LBA valve body be replaced with an LBA valve body without any other changes, or is it best to pull the trans when you swap them?
