It's a beautiful day here in Southern Ontario! About 60 degrees.
I took my '63 convert out for a country spin this afternoon.
It's been going on since I bought the car but never got around to asking the Forum about the shifter that kind of rattles when under a load. It's not bothersome to anyone but me.
It's a 327/300. I assume it's a muncie but I haven't been under the car to check. It shifts perfectly fine, clutch engagement is excellent and runs like a dream.
Any idea what makes the shifter rattle? If I lay my hand on it, it becomes quieter.
Thanks
They all seem to rattle, it's very common. If you look at old posts you'll see what I mean. I and many others have tried to cure it but the only cure seems to be a Hurst shifter conversion. I'm adopting the old "if it aint broke don't fix it" attitude. Gary
Thanks Gary. I guess I should have done a search first.
Good know there is a fix in the Hurst conversion.

Seems the transmission mounted Muncie shifters suffer this the worst. My '64 had a bad problem with this at freeway speed. A new rear housing bushing and slip yoke, and having the drive shaft and half shafts rebalanced made most of the vibration problem go away. A bit of shifter buzz/rattle is still there, but comes in at higher (than before) freeway speeds.

I just kinda chuckle every time a noob posts this topic. Been there done that, got the Hurst! I used to wrap a towel around my 66 to hush it up. It's even worse on short throw. I rebuilt mine and it still did it before I retired it. Some people here have dealt with it but I suspect they use the long throw position with rebuilding. Have fun.....from Ottawa.

You don't state whether shifter is original or aftermarket. Original '63 shifter had a spring on the lower part of the lever. If spring is missing shifter will buzz some.
As I recall, there was a factory correction for this that was documented in a GM Service Bulletin for '63 shifters. Seems the solution is to cut up some of the nylon window-crank spacers,creating small "C-shaped" washers that can be slipped behind some of the shifter pivot shafts to take up the slack.
Sorry for the rough description here - but if you search around on this or other Corvette websites - I'm sure you'll find the Service Bulletin posted by someone. The fix is clearly illustrated.
I rebuilt the Muncie shifter on my '66 with the rebuild kit that is available from most of the vendors (along with John Z's tech article from a few years back) and it's great. Plus, I love that clunk-clunk feel of the Muncie shifter.
I thought I would give an update on the rattling shifter. ....
I bought a new rubber O ring as someone suggested. I unscrewed the **** and installed the O ring. Although it still rattles slightly, it's noticeably better! Thanks for the help.
