Transmission won't down shift unless you release gas pedal

Maintenance/Repairs

99 Grand Marquis. Transmission won’t down shift unless you release the gas pedal. Check engine light not on, no OBD codes. Changed the transmission fluid and filter. Fluid level OK. Suggestions? Cheers, Tom2.0

Do you mean the transmission won’t UPshift into the next gear, not downshift?

.oh…good question. Thank you. You are correct.

I stated the problem incorrectly. The car won’t UP shift.
