Sorry I could not find a better image for you, but If you look at the diagram you'll see that #9 & #15 are your range forks, #11 is the SHIFT MODE SYNCHRONIZER ASSEMBLY. Your problem lies therin for some reason you have a binding issue and I agree with Htech that it is probably your range forks which may be damaged, if it's under warranty have them open it up and have a look. Worst case scenario is that they replace your T-Case.
