I'm sure you already checked, but I need to ask. You checked your trans fluid level correct?

Check underneath truck, side of tranny shifter linkage is free and moving by hand (make sure to chaulk the wheels)

Are you saying the gear selector is stuck, or it just won't down shift any more?

Sounds like there is a valve or something stuck in the valve body.

Smell the trany fluid and if it doesn’t smell like burnt almonds then it’s probably fine, just needs the valve body cleaned.

A great time to buy a new valve body shift kit.

If it smells burnt then you need a rebuild.

It could be the vacuum modulator “don't know the correct name” it's that round thing on the right site of the tranny with a vacuum line on it.
