1992 Chevy C1500 2WD 4.3L V6 with 5-speed manual transmission. Transmission would not disengage. Took the transmission out and found that the pivot ball had pushed through the clutch fork. Both parts are worn, so pulled out the clutch fork and pivot ball (it slid out when we pried on the fork.... since the pivot ball is mushroom shaped, it was "stuck" and pulled the pivot ball stud out with it). So now I have it all apart and I have two problems. One is that I cannot find a pivot ball that looks anything like the one that came out. The closest one I've found has the same small stud on the top of the pivot ball, but the back is threaded and appears to go in from the back. Mine is shaped like a smooth stud and appears pressed in (but no idea how to press it in with stud on the tip). So, where do I find the right stud and how to I install it?
The one on my full size chevy is pressed in, i got a new one from the dealer and pressed it back in by putting a 19mm deep socket over it and taping it in with a hammer

the axle just pulls or snaps out of the trans, it is held in by an internal round spring clip, they are a real bear to remove the 1st time, u must pull straight out with a sharp jerking motion to get them to release, be patient it will come out.

I would want to see that for myself, or get a second opinion. That really sounds suspicious since they claimed there was rust in a box that was mostly filled with oil. And I can't see any logic in paying a lot of money to fix a transmission that is working. Why don't you take it to another shop and ask them to change the transmission oil, and to save the old oil for you to look at. It would be even better to change the oil yourself. Don't tell the dealer what you are doing. The best thing would be to just pick up your car, as is. If it is a scam, they could put some stuff in the transmission if you give them time to do it. In fact, they may have already done that. I can't say it's a scam, but it sounds like it could be if you haven't done anything that would have broken off teeth in the transmission. And if teeth are broken off you should be able to hear it while accelerating at low speed in each gear.

Found the solution. Finally found the right stud (P/N TS290).
Just FYI to those that don't know (I am always working on my own cars and I had no clue) there is a grease fitting on this transmission. The grease feeds into the (hollow) pivot ball and lubes the spot where the clutch fork pivots on the pivot ball.
I guess 150,000 miles of this grease fitting being ignored was enough.
