Whenever I am accelerating hard and it downshifts from 4th to third and then back to 4th, it does not "hit" like it does in other gears. From 1-2, 2-3 it gives a nice little hit when shifting, and also from 3-4 when under light throttle. But when I'm on it, and it goes into 4th it kinda eases in. I don't know if this is slipping or flaring or nothing at all. I know about the B2 piston problem in these 126 trannies, and wondering if mine may be on its way out. 170,000 miles in case you're wondering.
