Since posting this, I have adjusted the bands and backed out the adjustment screw 2 turns on the modulator. Things have improved, some, but most of the problems remain. My '94 has the A4LD, not the 5R55S.
Downshift into first sometimes clunks now, but it doesn't matter if it is a coasting decelaration, light throttled on uphill, or a braking stop. Downshift is the 10-15 mph. The upshift is 17 mph. Before the adjustments, it was a firm bam, every time. Now, there is sometimes a thunk before shifting into third, or right at it. It is usually very mushy, no notice of the shift except for the tach dropping. Sometimes it does it in 2 stages.
Acceleration is fine, no slipping. BUT! It may decide to wind up and not shift into second, or it can act like it is in neutral. (It corrects itself if I manually downshift). If I stop, turn off ignition and start again, or go into neutral or park and back into OD,it can behave normal. Sometimes it may take several tries.
It can act like it has no power going up a long hill and throw the Check Engine light. I've checked codes and no trans codes are thrown.
