63 muncie

[jim cear]

When upshifting from second to third I have to have the clutch fully depressed to the stop otherwise I'll get a slight grind going into third. Clutch is adjusted with adequate play and the trans. was rebuilt 3 years ago by a respected muncie specialist. Could this be a linkage adjustment problem? Thanks

There are two styles of blocking rings used in Muncie Transmissions, 63-65 using a first design and '66-up using a second design. They are not directly interchangible, and failure of this part will lead to the problem you have described. Virtually never a linkage issue for this problem.

Re: 63 muncie

another possible problem is the retainer ring that holds 4th gear on the end of the main shaft---all will be well until you get after the throttle and try to shift quicker than usual--or "bang" a gear---then you notice a "grind" like the clutch is not releasing cleanly---i agree with bill on the linkage issue---good luck with it,phil

spoke too quick ---------------

the lock ring holds the slider hub against 3rd gear---so if the ring is missing or ? you will push 3rd gear around before it gets engaged all the way---chased my you know what years ago on an LT1 M22 until i figured out what i had left out---it shifted fine until i got after it---good luck,phil

How much does a Muncie weigh ? In other words, when I'm on my back slidding it out is it gonna be painful?

Re: 63 muncie weight?

its a handful but my 62 year old carcuss can still handle a muncie or t-10. not so with the ZF6 in the c-4's. first ZF6 i removed by myself several years ago dern near sent me to the hemorrhoid doc.i'd guess the muncie weighs about 70#. mike

In just about any Corvette I've ever been involved with one way or another, clutch adjustment is a "touch-and-go" situation. In general, I have found that when you have the specified free-play, it will require the pedal to be absolutely at the limit of deflection to completely disengage the clutch. What I try to do is get it to where it has minimum free play (but, still, a little). This results in more positive disengagement of the clutch with the pedal depressed.
