This is a 722.108 so no vacuum modulator.
The control linksge has been shortened and lengthened several times to no avail. Curious thing is when I can get it to go into third, if I hit the kick down it goes to second and when I let off as a normal person would as I get to speed it will upshift back to third easily and then into fourth. And downshifting always seems to go through all 4 gears when coming to a stop.
The car doesn’t feel as though it’s locking up so it’s something with the transition from the B1-K1 I would think. If this were a working pressure or any other system pressure issue, wouldn’t it have an effect on the other gear changes as well?
Maybe both the original valve body and the one I swapped in have a similar issue?
