Meaning, I should drop it into low gear for it to go in...?...there is a green flourecsent ring in the way and I'm afraid to force it in ..

 

I believe that is correct. You want the gear selector in the position furthest away from the opening, so you don't have to compress the NSS as much. The spring in it is pretty strong and a pain to install. Fairly sure that's low gear position. Checking.

 

INSTALLATION
(1) Move the transmission manual shaft lever to the manual LOW position.
(2) Install the TRS mounting bracket into the transmission case. Using Adapter 8581 (Fig. 257), tighten the mounting bracket to 34 N·m (300 in.lbs.).
(3) Install the TRS (Fig. 258) into the mounting bracket with the wiring connector facing the front of the transmission.
(4) Install the two screws to hold the TRS to the mounting bracket. Tighten the screws to 3.4 N·m (30 in.lbs.).
(5) Verify proper sensor operation (Fig. 259).
(6) Move the transmission manual shaft lever to the PARK position.
(7) Connect TRS wiring connector to the TRS and lower vehicle.
(8) Refill the transmission fluid to the correct level.

 

Where can I see the figure pics your referring to..? 257 & 258

 

the mounting bracket is already in your case. The TRS only goes in one way, where the 2 bolts line up.

This is from the Factory Service Manual.
