Ouch, no its certainly not that bad but I've looked at it again and yes it does have a very slight twist going I'd say.

Damn 60E's!

Tearing into the transfer case to swap out the input shaft so it will fit an 80e. Already a good write-up on the board that I referenced for this. Thanks Wilde... Still gonna add my 2 cents.

Found this clip piece laying under the pump pickup. Had to pack up and head to the dealer. Luckily he had the new design clip in stock. Also had to pickup up some more tools.... 12mm allen for the next steps. I'll show the new clip later.

Transfer case is all buttoned back up, mostly. I tore up the front seal getting it out and can't get another till next week.

This assembly will just lift out with a little finessing.

Lift this fork out, and pull the rod to the right. Some fancy manuvering will then pull a gear out of the spiders and the shifting mechanism. Take your time here.

Some case damage form the clip breaking. I'd had a leak here eventually about half the case wall gone.

Had to flip the case over like this to allow everything to settle downward to get the final c-clip to snap back in. This was a PITA.

Hmmm... no comments the last couple days. I must really be boring everyone

Some of the wiring this morning.

The main connector with the cover removed. Pull the rubber plug back to give some room to pull the 2 wires necessary.

Well on to getting the speed sensor wired. I actually gave up on this earlier. The key was getting the damn PCM connectors up to where I could work on them. I actually pulled the PCM out to get it out of the way. Probably not necessary.

Once I got the connectors up to where I could work on them after getting the back covers off, I took a small drill bit and ran it through the pin locations to open up the water seals. I've seen a paper clip used but couldn't find one.

I also could not get the pin to fully seat into the connector. I even looked at a previous pin I'd put in for the electric fans it was the same way. May be common knowledge but I've not seen it mentioned but after fooling with this I'm gonna say that you cannot get PCM pins all the way in without removing these covers I've pictured. The caps lock the pin locking tabs down and don't allow them to flex out of the way as you slide the pin in.

The pin for fan done couple years ago. I also took it apart and fixed it.

A shot to show how I managed to get the connectors up where I could work on them.
