C2 Muncie Close Ratio 4 spd. Diagnosis

[Wayne K.]

I've owned my 67 L79 for 7 years and since I've owned it I've had this issue with the transmission and would like some opinions.

The issue is when I want to shift the transmission fast it clashes the gears. This only happens on upshifts. The clutch and linkage seem to be fine and if I use a slight hesitation between upshifts it isn't a problem. It hasn't gotten any worse over the past 15,000 miles but I know this shouldn't be and would like to know what the problem is. Thanks in advance for sharing your thoughts.

Sounds like it needs new Synchro rings.

Second the motion, a new set of brass blocking rings (suncro rings) should do it. While it's apart, new seals, bushings and misc. parts should get you back up to snuff.
