I have a 02 dodge dakota 3.9l v6 4×4 and I have a transmission problem. Heres the problem. I turn on my truck and I turn on 4lo I start to slowly release the brake pedal and my tires lock up. So I stop the vehicle. Then I turn the switch to 4hi and it does the same thing as 4lo. I turn the switch back to 2wheel and I turn the steering wheel to the left and the LF wheel starts to lock up. I start to fiddle with the switch and I turned 2 wheel back to normal. My guess it is the transfer case. I want to hear what you guys think. Also, I am wondering if I can replace one part without getting a rebuild kit. Or not getting it fixed right away or until I can get enough money for a rebuild kit and labor.

Any CEL?
You may have an issue with the mode selector on the transfer case itself.
Does it go into gear when the vehicle is raised off the ground?
I just found out today and I havent tried to diagnose the problem yet. I dont have a CEL. Nor any lights on the dash.
To me it does sound like it might be a transfer case problem and not a transmission problem. If the transmission shifts fine in 2WD then it’s not likely to be a transmission problem. If the chain is loose in the transfer case or there is some other issue in there it could cause a condition like that. You might pull the fill plug to see if there’s fluid in there, if it’s dry then that may be the problem but the damage may have already been done.
If you are doing this on dry ground or pavement it might not be anything to worry about. Here’s why. Each of all four wheels on the truck will wear slightly different than the others. This can be from the alignment, tire pressure, shocks, road conditions or driving habits to name a few. When the tires are not exactly the same diameter they will spin at different speeds. Now normally the differential in the axle will compensate for this small difference in speed and you will not even notice. The problem comes when you engage the 4×4 on a surface that does not allow the tires to slip. When the transfer case is sending power to the front axle as well as the rear the difference between the front and rear wheel speed difference is not compensated for by the differentials and this will cause the drive train to bind. If the tires are not able to slip some the transfer case can be damaged from this binding. That’s why the owners manual says not to engage the 4×4 unless you are on snow covered roads.
If you take the truck to a gravel parking lot or something you can try the 4×4 again and see what happens. I bet you will find that it is all good. Hope this helps.
