I almost rebuilt my t176 without asking for help...

I really thought I'd gotten my t-176 rebuilt without asking y'all for help. Everything seemed good until I put the shift cover and shifter back on to bench test everything. It keeps getting stuck in 4th. It'll go in and out of 1-3 great. Here's a picture of what seems to be causing the problem.

That little guy seems to be getting a little weird in there.

And the other two look like the one above.

I have to reach through and push the inserts in to get it unstuck. No way it's happening otherwise. Any help would be greatly appreciated.

Did you put the spring in correctly?

I believe so. They're alternating (120 degrees apart) like they should be. Only things I could see happening is if one of the "points" on the spring got out of the little block maybe. I guess it has to be something to do with the spring.

All of my bench testing is without the transfer case adapter bolted up if that makes any difference. Also it'll go in and out by hand pretty easily with the cover off. It's almost like the shift for pushes it too far.

did you ensure the proper little plates are installed in the 1/2 shift clutch vs. the 3/4 shift clutch? They are different sizes.
Only other thing i can think of is the shift fork is moving the shift clutch too much. I put the trans in neutral, position the shift forks to neutral position, then install the cover while looking into the trans to see how the shift forks are lining up with the shift clutches as the cover is lowered... at least as much as i can see.

didn't see this info as i was typing my response above, but, yea, install the adapter and the front bearing cap to hold the shaft and bearings in the proper position. Could be the problem right there.

I agree, need everything on before testing it.

It may be the main shaft moved back too far allowing the 3/4 collar to move too far.

I made sure the correct size plates went in each one, so I know that's good. I have the front bearing cap installed. Guess I will see what happens bolted to the adapter. Like I said, it will shift fine by hand as you can see in the pictures with the top removed. The forks seem to push it further forward.

Really hoping to not have to pull the bearings again...

I just rebuilt my T-176 with Grand Pa, and when it was moving that collar too far we were getting really worried! We were checking to see if we missed a thrust washer or what, but we had simply made the same mistake of testing without the bearing cap and the T-case Adapter.

Glad you got it fixed!

One more question for y'all. Is it easier to put everything back together with the transfer case adapter on the trans or transfer case? I'm thinking attached to the TC since you have to use sealant on it. Thoughts?

It was easy with it attached to the tranny.

But I never thought of doing it the other way.

Did you use permatex between the adapter and transfer case? It had blue RTV on it when I pulled it apart, but I wasn't even sure if it needed a gasket at all.
