When shifting very quickly, the car sometimes grinds into second. What i'm thinking is the clutch line might be swelling too much. Would my issue be resolved with a mazdaspeed braided SS clutch line?
Thanks.

I think it may be the timing of your shifts (in relation to your clutch pedal stomping), than the clutch line. The clutch line doesn't exactly swell up like a balloon. It does expand a little bit, but given the age of FCs, the clutch line is usually cracked (at least on the cars that I've worked on in the past).

 

have you adjsted the clutch pedal?

 

woah, me too man.. new tranny fluid helped, but still the odd time itll grind into 2nd..

that and also while the car is dead stop, if i pull the clutch out just enough to keep the car from moving, WITHOUT MOVING MY FOOT it will slowly roll forwards then stop then slowly forwards again, then stop..

 

No i havent adjusted the clutch pedal, frankly, i don't know how to

But i think its the fact that the clutch is disengaging slowly due to tired hydraulic lines.

I should try adjusting it first to see if that does it. Anyone have a writeup?
Thanks

its simple. well, depending how big you are. look up under the dash towards the top of the pedal. you'll see a shaft going through the firewall that is threaded. there is a locking nut that is tightened against the top of the pedal. back it off then twist the threaded rod. you can probably do this with your fingers. just keep feeling the pedal to make sure you are taking play out instead of putting more in. the key to it is to get the pedal tight without causing it to slip. once you hit this balance it will only take a jab at it when changing gears. most people don't think about this when getting short throw shifters. there are 2 things to shifting speed, time on the pedal and time moving the stick. anyway, i think i covered it all. its a very simple straight forward thing. just don't over tighten it as you'll start to slip the clutch.

 

wow, i didnt know u could adjust the clutch that way!! someone told me u cant adjust the clutch on my 86 GXL, thanx!!

 

ever thought that it might just be the synchro? You know, these aren't new synchros either. My car used to grind into 2nd a lot, I changed the fluid, problem solved.
