Make up an additional ground strap and run it from trans to chassis
Make sure the trans mount is not broken

Thanks for the reply.
I drove it again this morning to see if anything had changed, and it started shifting harshly from a cold start. I don't think this changes much in what to look at.
So far:
TPS - good, verified through OBD2
VSS - good, verified through OBD2
Pressure switch assembly - will check
Trans temp sensor - any suggestion of how to do this?
ECT - good, verified through OBD2
I'll add an additional ground strap and check for the broken trans mount later today.

Your symptoms say the pressure is too high. That could certainly be the result of a trouble code (even pending).
I think I would install a pressure gauge just to verify correct pressures.

You are correct on the ground issue recall. Mine has been done.
I agree with the pressure being too high, but there are no trouble codes stored or pending.
I don't own a transmission pressure gauge, but will probably buy one.
