I think the Band Break is like the B2 piston break when it happens you no forward motion.

Yeah, here is my B2 ordeal. About 4 years back. Things worked for another year and a half then the trans started making funny noises and doing crazy stuff two years later after. I went ahead and put in a rebuilt tranny at that point. No regrets, the car has never run this well.

Blew my B2 piston

There’s some details on the puller to get the sleeve out. Funny seeing my attitude back then. I thought I wouldn’t own the car much longer..., funny. That was only 5 years ago and I feel like a i was a different person.
