He's not driving in Low and then shifting to High and wondering why it isn't smooth is he? That never went smooth for me in mine, and i don't think they sorted that out until later versions of the tranny.

If you're at a standstill, and put it in H, it should want to go into gear "Right now" or with no undue delay letting you wonder what's up, like a modern tranny would perform. You should be able to "rock" a stuck car between R and forward gears.

I believe Ross pointed me to the seals around the servo pistons if that's not how it's acting.. Think part of the piston is the little one that "raps" and gets the bands attention and then the larger one does the work? I didn't study it that well, 51packard's thread has valuable info on that subject (and other ultra related info)

Anyways, those seals could be an issue, they dry up and they are critical to keeping pressure proper.


It would "sound" like, from your description of working on the lift and not on the ground, that you're REALLY low on fluid or acting like it (not getting to converter like you said), which is dangerous, or that you're not all the way in gear?

There really needs to be some pressure testing done, would sort all this out in about 10 seconds.
