1996 S10 V6 5 speed Manual Trans NV3500 Disassembly Question

OK, after making it through about 600 hurdles, Houston, we have transmission on the ground! I repeat, we have transmission on the ground!

Thanks for all of the prior help. Now I have new problem. hehehe

First thing I noticed today was no oil drained from tranny when I pulled plug. Bad. 2nd thing, once it was out, was that there is a secondary noise inside the box when I turn the input shaft. Rather like a caaalump as I start to turn it. OK, well it's out, how hard can it be to split her open and see what's toasted in there. lol

All of the bolts are out, the snap ring on input shaft is off, the cases split ok, and moved apart about an inch (just as alignment pins pull out completely) when they stop dead. an unknown piece fell out inside, and now it won't go back together or come apart.

I've had a few different trannies apart over the years, the toughest probably a ford top loader, so I figured this would be no big deal. I guess I was wrong.

The shifter fork shaft goes into a lump on the inside of the bell housing. On the outside of bell housing, aligned with the shaft and the lump is some kind of pressed in plug. I can't help but think that the clue to this dilema lies hidden behind that plug.

Am I close? And if so, how does one get that frozen, rusty, hard to grab thing out of there without destroying anything? lol

Thanks again folks!

I found an exploded view of this thing, finally, but it doesn't really answer the question. Just posting it here for future reference.

OK, here's an NV1500 exploded view with a little closer view of the shift fork shaft:

I guess it's safe to assume that the shift shaft detent (parts 27, 28, 29 on the 1500, and 68, 69, 70 on the 3500)would also stop the shift shaft from moving too far rearward, and thus probably be my problem. Now to get that plug out. yuck.

Detent Plug Removal

OK, I have answered all my questions.

Here's link to a description of shifter shaft detent removal procedure:

Requires special tool. I'm going to drill and tap the plug, and using a socket that fits around plug and an appropriate bolt and flat washer, make a puller and draw the plug out with the bolt.

Posting info here for posterity.

Drilling and threading didn't work. Drilled plug to almost its full diameter and was able to pry it out then.
