remove the inspection cover under the torque converter and check for failed flexi-plate drive. The plate that the torque converter is connected to that is attached to the crank shaft. Check the torque converter control (TCC) clutch solenoid/servo for failure.

stuck valve in the tranny in cold weather let it warm up before driving it then put it in neutral and warm up tranny if it does not slip then it is probably a sticking valve

if around 125,000 miles trans is going bad . possable bad planetary gears

This mainly is caused by transmission fluid level changes. Measure it when its at running temperature and in park. Add if necessary (most likely the cause)

Did you try pushing up on the shifter while trying to turn the key? Perhaps your grease is getting cold on the shifting mechanism and it needs new grease or oiling.

PCM going bad. real common

good day, you may try replacing your automatic transmission fluid, a good run will be noticeable, hope this helps, have a nice day

you need to have the PRNDL switch checked or replaced

call a mobile mechanic for a hands on look,without seeing this vehicle its hard to diagnose
