4WD AND 2WD

My 2011 overland is doing something weird that sounds costly and its diving me crazy.

When you first put it in 4wd (5-8km --Neutral and apply on 4WD) it works fine but it feels like it is hard to accelerate. But when you switch it to 2wd low ( the car jerks forward and brakes down drastically to a stop as if you were downshifting a manual car or applying the brakes. and while it is changing i can hear loud clunks and gears from inside the car.
Traction light remains on with the 2WD LOW
When i scan it there's no codes and the mechanics keep telling me everything is fine with the car but i know that's a lie

I drive it full time on 4WD and it feels like its gonna die when going up a hill and when reversing and turning the wheel right i can hear a dragging sound or as if the gears are catching or slipping

The car drives fine but it feel like its not working as it should. even when revving it, it feels like your feet is still on the gas even after removing it.

The RPM is way to high for the speed the the car is driving.

SOME HEP WOULD BE GREATLY APPRECIATE

There is no 2wd Option on a 4wd WK2 they are always in awd'4x4 mode to some sort.

Jeep Grand Cherokee WK2 - Transfer cases Sounds like your confusing the modes 4low does that it locks front and rear drive shafts together Not to be activated on pavement/concrete you will get that binding scrubing sound with turns etc. and yes in 4wd low you will get High RPM very low speed and when you let off it will feel like your hitting brakes due to the gear reduction.

You could try changing the Transfer case Fluid. You also didn't specify which engine you have the 3.6 or 5.7 .

For a 2011 idk how many miles on it or Km's change the tcase fluid uses 8mm Hex for the drain and fill.

Early 2011's with 3.6's there was a TSB for the torque converter shudder on take off or fish bite feeling also.
