Dodge 05 5.7hemi automatic, will not move unless the rpms are over 2000

just an idea but check the rear brake emergency shoe linings inside the rear disc rotor. Have seen them randomly fall apart and cause as you described. plus it's free to check it out, hope this helps.

rear brake rotor removal is necessary to check this

could be a stuck handbrake. If it is cold they can freeze stuck, depends on where you are.

I tried the handbreak as well but nothing

Did you check if the handbrake line moves where it connects to the brakes at the wheel ? If it does not move it is stuck. You might need to take the brakes apart and then put the handbrake on and off to see if it stuck or not. If you don´t see any movement when you put the handbrake on or off it is stuck and you need to fix that.

Brakes work fine. Engine light is on now

Check the code

Could be the timing as we'll

I found out the codes are P0842 and P0700 first is a tranny fluid sensor second is a general tranny malfunction. DURANGO before this never had to go over 1500-1800 rpms. It started again a couple days ago but it is still draggin bad

Looks like a tranny rebuild, they need service on time or else they will go bad, take it to a tranny shop you trust and let them take a look at it.

Sounds like it is low on fluid or the filter in the bottom of the transmission pan is half stopped up
