Default Muncie 4 speed, Ive got issues

I need a gear box Guru, I currently have a Muncie 4 speed S/N 3925660 & 8088336 1968-1970 on a 4.6l 283. Sitting in a 1960 C1. Problem is it Drops or pops out of first gear at the lights? then I cant find a gear to select, even doubling the clutch? Ultimately I end up forcing it onto gear to get going. Normally happens during a decent run & or when on an incline? Clutch is good, Oil is correct & linkages feel smooth? because it is intermittent Im not sure where to look? my mechanic is reluctant to drop the gear box because on testing we cant replicate. help appreciated. I'm in New Zealand in the deep south Island.

Hello, this Help section is for Help with the CorvetteForum website (account issues, etc.,) and is not the place to post technical questions about Corvettes, or other questions not related to the website, as they will not be seen by other Corvette owners.

Instead, please find the correct section, based on the generation of the Corvette.


Go back to the main forum page:
https://www.corvetteforum.com/forums/

Now start to slowly scroll down until you see your generation of Corvette listed. C3 (1968 - 1982):
C3 Technical: https://www.corvetteforum.com/forums...performance-3/

We encourage new members to take some time to browse around the site and read the Announcements and Stickies as they contain important and frequently asked information.

Thank-you
