Really? The shifter am I insane?
I just changed the clutch on my C5 racecar having never done this job before. I never noticed if the shifter is sloppy with lots of play left to right in neutral before the detents kick in when you upslide to 1/2 5/6. Was the slop always there? I look at the shifter and I can see the shift rod rotate until the detent in the shift rod gets stopped by the bolt in the retaining assembly. It is a locking block style with a delrin insert. Weird design! Why not put a sleeve around the oem bolt to close down the clearances and dramatically sharpen the shifter feel? Anyone try that? I'm I just crazy? Opinions?

It may be that there is one there too as this would be a simple way to make that long rod connct the shifter to the tranny. I'm just shocked by the amount of "freeplay" in the shifter that I never noticed before. I'm thinking of trying to shim out that ffreeplay with a delrin sleeve over the installation set screw. Then when the shifter moves it engages the detents for 1/2 and 5/6 faster.

There is a rubber piece that is on the bottom of the shifter box and slips into a slot on the torque tube. Maybe that fell off and is allowing the box to flop around. I shimmed that rubber piece so it's tighter in the slot and also shortened the sleeves in the two screws that bolt the shifter box to the torque tube. It tightened up the whole assembly and I don't notice any increase in vibration.

Nope the box is not the problem it is the little pee-pee that comes off the end of the shift box with the detent that indexes only one way into the shift rod. There is like 3/16" play left and right of center which means the shift patter ball in your hand moves left right 2" before anything happens. I can't remember if that is the way it was before I took it apart. See the red dot in the picture vs. the center line on the shfit rod lock.

Is the plastic piece on the very bottom of the shifter shaft? That seems like a lot of slop. Looks like your running the stock shifter which a lot of us have changed out. I run and MGW and it's world's better than the stocker.

Mine does not have that problem. In fact, it was a VERY tight fit when I put everything back together a couple weeks back. Take the bolt out and make sure the bolt its self is actually threaded through the notch cut out on the "pee-pee" I made that mistake the first time.
