if the car were still running, i would unplug the large connector to the trans located on the back of the engine. (largest of the three.) this will disconnect the TCU, put the trans in limp mode, third gear only, and cause ''binding'' in tight turns. if you get the binding, this means the mechanical stuff is ok in the transfer case and the problem is probably else where.
I did this and did not get any torque bind. I’m thinking it’s the transfer clutch solenoid. ButI want to make sure before I tear the tail end of the transmission apart to change the seal annoyed out as I will have to be making my own gasket in order to put it back together
