fyi GM factory pins are not multi coil. BTW changing roll pins in the car is a pita. I mean a real pita. Drop the drivers side mount the rear mount, remove the shifter cable bracket, go in through the drivers side fender well, its awful to get the roll pin punch in there, and if the pin is in hard it can take hours to get it out as you cant swing the hammer , too much in the way.I would almost say take the trans out or drop the cradle to make it easier. But if the roll pin is broken and its an LSJ car, it comes out easy. LNF are a beatch.
You don't have to do all that. Most I've done was remove my intake and fuse box.
Then just giving tools purposes they weren't made for. I've done it this way twice.
Either way, no matter how you do it, it's a PITA.

After that, I didn't have enough room or leverage to get it all the way in. I moved the fork (into what was said 5th gear) so the pin was facing the front of the car, and used a screw driver as a lever and pushed forward on it while using the mount as a fulcrum. It pushed the pin in no problem, and pushed the broken piece out the other side.

The one I initially changed was a coilded pin. I bought the car with 8000 miles on it and never changed it before then. I wonder who put that in, if its not stock?

If anyone is interested in an alloy steel (5,900# break strength) or titanium (5,500# break strength) pin, I just found some for one of my racers with a 2008 SS/TC.

I just completed this earlier this morning. Great write up on showing exactly what to remove. On the other hand, I hope people dont run into what i did. Pin broke in like 4 pieces it was a pita to get all of it out. But still not that bad at all. Thank You OP
didnt have to remove any trans mount but did remove the cable bracket

Doing this didn't fix my problem. I'm at a standstill now. Could the hole in the piece under the linkage be wallowed out so the pin moves back and forth when I shift still causing play in the shifter?

I was reading this thread, and the thought of a roll pin going out in the middle of norwhere makes me kind of nervous about it. I'd rather take and do preventative maintenance before something does happen. What are some of the signs of a worn or broken roll pin?

Ok guys I am having the same issues. I have all gears it seams as thou 1 3 5 are a much longer throw and 2 4 R I almost don't have enough to get them plus when downshift 3-2 it pops out the first time. I had catastrophic failure of this pin at around 400000. Now with 122000 it all feels sloppy and 2nd is a pita. I am brand new on the net here but not to the balt. I cannot believe all this slop is from a little pin. When in gear the stick will move over an inch before disengaging gears
I have the MU3 tranny.
I crawled underneath and the roll pin is sticking out one side by about 3/8"
Has anyone tried to use a small c-clamp to get the new pin in?

you need a good roll pin i have a few hardened ones left. its a PITA.
jack car, remove driver side wheel. drop engine mount down by releasing the bolts under the fuse box.
get a snap on 3/16 roll pin tool and a very short 4 or 5 lb hammer.
remove as much stuff as you need to get to it, the shifter cable tree will help
remove replace. ez.
not
good luck
ps gelladuga said he did his removing the fuse box. that may be easier, not removing the fuse box thats a pain, but its all an issue how to get a good swing with the hammer to drive the pin out/in.
every trans we rebuild goes out with new pins lol
