Transmission may now be toast since you continued to drive it when maybe low on fluid or torque converter had failed. How long since last fluid and filter change? Ever?

Sounds like one or both of your universal joins is going bad... Is your mountaineer a 4wd, front wheel drive or rear wheel drive?

You have a broken part inside the transmission, it will need to be torn down and inspected.

Sounds like the problem with the Crank or Cam sensors.

most likely if this happened all of a sudden your gear shift cable is bad or had become detached if the shift er inside the truck feels very easy to move between gears it is the cable and the track has not showed signs of a bad transmission in the recent past see link Dodge Durango shift cable the easiest way to repair Kit includes...

The transmission solenoids are not working properly. Probably requires a transmission rebuild.
I don't think it's in the ground strap or wiring.
It's an internal problem with the transmission.

It's usually a carburetor, or clogged fuel injectors. Other times the fuel filter is clogged.

check the oil lever in the transmisson assuming it's automatic, if the fluid level is fine then with it in gear running and the brake on look to see if the drive shaft is turning, if it is then you have a prboblem with the drive shavft depending on engine size and wheather it's front or rear wheel drive. if it's not turning then you have a transmisson problem. If this is helpful please rate.

Your brakes have seized. Remove the wheels and inspect. A firm blow with a rubber mallet to the calliper or a little penetrating oil may free them up, but not adviseable to drive until looked at after freeing up.
