Default Shift **** Removal - Help please!


Tearing things apart today to install short shifter. Having trouble getting the stock shift **** off. Is this threaded hole in the retainer used in some way? Tried clamping vise grips on the retainer but can't get it to budge. Need suggestions. TIA.

Regards,
John

Somebody has boogered that up previously. I would try taking two screwdrivers and come in from the sides and pry upwards on the wedge.

I can’t really see a lip that I can pry on. I’m thinking of threading a bolt into the hole and using a slide hammer. The threads go all the way in. Thoughts?

Looks like someone epoxied it on but I don't see haw the button works. There's supposed to be a c clip down there under the epoxy. Maybe try digging out the epoxy and see if the clip is there or not.

There’s no epoxy. It’s just the reflection in the picture. If I can fit the slide hammer to it, I’m hoping it will pop it loose.

I've used a 'slide-hammer' before. I had a very short maybe 12" - 14" one. Used that 'shorty' for many things!

Some people drill and tap it so a steering column pivot pin puller will fit it. Works really good that way.

Probably someone snapped the C clip that holds it in place and didn't have another one and boogered a way to hold the **** on forever.

What year? My 96 only has the wedge. It is a soft metal and think threads that small would just strip out if you put any real force on them. I used a small set of vice grips and wiggled it bit by bit until I got enough out to get a solid grip on it and yank it out.

Damn guys, there is no c-clip on the ZF ****. It is just the wedge that locks it in place after screwing the **** down. You can see from his console/radio it is a 94-96.

Default Success!

I got the wedge out. The hole someone drilled and tapped into the wedge was 8-32, full depth into the wedge. I drilled out the slide hammer shaft and threaded it 8-32. Them I cut off the threaded portion of a long 8-32 bolt and threaded it into the slide hammer shaft and the wedge. All it took was a couple of light raps with the hammer and it popped right out. I think GM should have done it this way to begin with. All the load is right in line with the wedge, and you don’t have to worry about damaging the leather **** by prying against it.

Thanks to all who offered suggestions! Next step is removing the shifter assembly...

Regards,
John
