Maybe this is the problem, the tub sleeve bearing seems to be frozen on the transmission neck and there was little if any grease between the sleeve and the tub. Perhaps this is the bearing that caused the belt to burn.
So if there a trick to removing the sleeve bearing?? I've tried squirting it with PB Blaster, prying it with a screwdriver, twisting, pulling but it just won't come off. Unfortunately the new transmission did not come with a new sleeve bearing so I'd like to reuse the old one if possible.
