transmission linkage problem
I have a 1964 corvette with a manual 4 speed munsie trans. I am having a problem with my trans linkage. Everything was fine until a nut unscrewed on my 3rd and 4th gear linkage on the transmission handle. Put on a neew nut, but it I had to put the nut almost at the end of the rod to shift gears. Not every once in a while tthe linkage hangs where I cannot use the shiifter except for reverse, and i am in third or fourth gear where the shifter is in neutral. I know that the shiftersw on the trans have to be at about 11 oclock (neutral) to adjust the nut to line up the linkage. I also knoe that there should be a pin to center the shifter linkage but i do not have that pin. The shifting was fine for a couple of week after I reconnect the rod that the nut came off, but then I tried to go from reverse to first gear and the linkage hung.
My quests are 1. is there any other way to adjust the rod going to the 3rd and 4th gear from the shifter to the side of the trans. 2. To remove and replace the shifter do I have to remove the transmission from the car, or can I do it from the top after I remove the console....thx russ lildrip049@aol.com

This might help you. It is from a previous question on the shifter. Is yours a stock 64 unit? If so, the upper photo in the JohnZ's first post will help you.

Since your problem started after the 3-4 adjustment came loose, that's all you need to adjust. Adjust the 3-4 rod until the shift handle will slide freely back and forth, without catching, across the R, 1-2 and 3-4 gate with the lock out handle pulled up. It's easier with a helper.
Sometimes you can put the handle in reverse, then pull it back to neutral and shake the s..t out of the handle while holding to the right and the linkage will come unjammed.
Or, you can unhook the 1-2 shift arm to get the linkage unjammed and then hook it back up and adjust the linkage.

I have a 67 and I replaced the shifter from the bottom. (I had the same issue with mine after 43 years of use - shifter linkage binded between reverse and 1st gear.)
Nothing other than removing the shift ball and the reverse lock out collar from the shifter inside the car is required. Boot and console remain as is.
Remove all the shift linkage rods from the shifter and remove the shifter mounting bolts to from the tranny and the shifter literally falls out.
All 65-67 shifters have the adjustment slot, easier to deal with when adjusting the 3 linkage rods. Replacement shifters for 64 are listed as the 64-67 Shifters.
A very good source for the new shifter is Volunteer Vette Products - http://www.volvette.com/SH005.html
Replace it and your worries are over!!

64 vet linkage alignment
Your problem is easy to fix without that "pin".

MikeM, I tried doing what you suggest with the 3/4 adjustemnt and the last screw on the rod but the trans is almost at the end by the transmission to get it to shift, but now it periodically "hangs"---I think that i need to put this pin to align the shifter in order to determine the adgustment on the rod...any other ideas thx russ lildrip049@aol.com

64 shift linkage
Had similar problems. Key was taking all the linkage off, buying new pins and new bushings (the plastic ones that mount on the shift linkage tab) for it all. I put it on a lift, installed the pin in the shifter housing and many hours later had it all done. Access was a bear and what took so long. I just found that taking all the linkage off, and updating the parts was the way to go. I do have the Hurst shifter.

.any other ideas thx russ lildrip049@aol.com
The lazy way is to spray brake cleaner on it to get the grime off and then spray it real good with white lithium grease while it's still on the car. May work, may not.
Replacing with a Hurst shifter is the coward's way out.

IMO start new and adjust properly and he's back in the game.
