'67 327 4 speed trans

[Keith N.]

When I shift, I have to pass through nuetral slowly to engage the next gear. The more quickly I try to shift, the more resistance I get when I pass through nuetral. Speed shifting is out of the question. When the car isn't running, it shifts as fast as I want it to, like butter, with no resistance at all! It seems like it should behave this way when I'm driving it, but it doesn't. I've never driven another '67 to compare mine to, is this normal?

abnormal. sounds like clutch not fullly disengaging when you depress the clutch pedal. try adjusting the throw-out fork rod's adjustment. how much slack, in inches, in clutch pedal on depression before meeting resistance?mike

Hi Mike; I'm not sure how much slack there is before meeting resistance but I did notice there is a faint "whirring" noise when I let the clutch all the way out. By the way, I was just fooling around a few months ago, trying to get a 'chirp' out of the rear tires (not smoke 'em off the rims)and couldn't do it. I was letting the clutch out fast, with alot of RPM, but all I got was a foul odor, almost like a burning smell. I couldn't get the tires to spin at all. I didn't want to "pop" the clutch altogether (remembering the car is 40 years old and mostly original)so I just skipped the whole idea.

sounds like it might be time to pull the tranny and replace the clutch disc, pressure plate and throw-out bearing. good luck, mike. btw, i assume the tranny is not empty of 90 wt gear oil.that'll make for difficuly in shifting , not to mention hard on bearings/shafts and gears.

Where is the plug (I should know but I don't). I'll check it out and I appreciate the help.

Keith -

Don't listen to the "local experts" when you adjust the clutch; the only way to adjust it (and the only way you'll avoid frying the throwout bearing, and possibly the clutch too) is to set it so you have at least 1" of pedal free travel from the pedal full-up position (against the rubber bumper) to the point where you feel resistance (from the throwout bearing) when you depress the pedal. You must also have the return spring in place so the pedal is always pulled up against the bumper.
