Yes it can gamage the TC driving it in part time 4wd.
What TC do you have?
Seems like the linkage is out of alignment. You can loosen up the bolt thet adjusts the linkage, push the TC lever all the way forward until it clics in the forward most position 2wd in the 242, or ful time in the 249, and then tighten the bolt up again.
When mine was either getting stuck or not getting into the right position, the bronze buhing was completely gone in the torque shaft in the TC, so it was completely out of whack everytime I shifted the TC.
I bought a TC linkage rebuild ki from chrysler, and it is all good now.
