Never again, you have gotten best practice from John B. and the others.
After having linkage issues the first 2 times... What I now do is ON THE GROUND, install the entire transmission and transfer case with T-case linkage and verify that shifting occurs in all 4 possible T-case positions before the entire assembly goes in.
The install is all in one piece with the main gearbox shifter left off... remember we are focused on the 4 T-case selections only at this stage of the "game".
Next with the vehicle on a lift, the main gearbox and T-case are raised on a transmission jack and slid into place.
Then from above, the main shifter is installed with the long lever, sound deadening schmekley.
The real finesse is the ability to jack the whole gearbox and T-case assembly up a bit at a time and get the diff lock warning light and reverse lamp connections in place along with the gearbox and T-case breathers and finally the handbrake assembly.
Completing this gives you an entry in the who's who of 90/110/130 successful transmission & T-case install registry of North America.
Unfortunately the bush league shop that did your work will never have an entry in the registry.
