How is your fluid level when warm? shifter linkage in good condition? Is the O/D off light on the dash lit?

I would assume a bad transmission solenoid but you also have a automatic transmission control computer in the passenger kick panel as well so follow the TSRM diagnostic category to try and narrow down possible causes.
