Is there a good place to start?

The PCM has "Adaptive Shift Strategy", Most likely not the problem.
The most likely cause is a worn 2-4 band or too much 2-4 band clearance.
The good thing is the 2-4 band is the "toughest" friction in this transmission, Even a worn band can be "shimmed" & work OK for awhile.
