That's the common "Pull Left" shifter. I'm not sure where you mean, but very little of the t-case is visible in your pic: only to the Right of the wire harness & connector near the Right side of the pic. You'd pry between the (relatively-) clean shift rod (coming from the top Right corner) and the dirty white shifter near the center. The shifter is bolted through the (oily) detent plate to the (grimy) transmission extension housing.
I got the thing off the truck. I didn't think they were so light.... wasted a lot time with an assortment of jacks and stands. In the end I ended up just grabbing it off and bench pressing it back in. :/
I cracked it open and found the triangle and a piece of the pump nozzle in the case. Didn't find anything else broken or any other pieces. Unfortunately the ridge in the case that holds the triangle in has worn through and I didn't have the time to do a full fix. I also couldn't get one of the snap rings out.. I think I have to buy a professional snap ring pliers to finish the job.
My plan is now to drill a hole through the case and insert a hardened bolt through to hold the triangle in place. Seems like a permanent fix. Would this work? I saw another fix with a rod welded into the triangle, but I can only booger weld, so don't want to try that. Don't want to risk broken off weld boogers floating in there.
Also I tested it out in all the positions while it's off the truck. It's smooth in 2H/4H, however when you go into 4L there is a resistance every rotation. Would that be the pump nozzle spinning around and hitting something that is in the way on 4L? I don't use 4L, so it doesn't matter... but I am wondering if something else is broken.
For now I buttoned it up as is and put it back on the truck.
I wouldn't add a hole to the case. Just bend a piece of thin steel into a trough that fits into the original slot, and crosses/blocks the worn gap, just like the plastic I used in my photo album.
The resistance is probably something between the teeth of the mainshaft gear, or inside the planetaries.
I finally got around to fixing this. I had to buy a new output shaft from US, because the pump destroyed the surface where it rides.
I bent a piece of (relatively) thick steel and drilled / tapped a hole in the case to bolt it in. The hole didn't quite end up where I wanted, but it did work nonetheless.
Pretty stupid design if you ask me. I did run the case for months and months (maybe even years?) without the oil pump working properly and there wasn't any issues. I am not sure if this thing even needs a pump ... Maybe it becomes an issue on long highway runs or something.
P.S. The case is made of some kind of really soft metal (magnesium or aluminium alloy)? It drills in seconds.
