Having a hard time with your clutch cable? Believe it or not, a loose ground on your transmission can cause your car to seek a ground elsewhere... you guessed it, your clutch cable. When this happens it can literally weld itself inside your clutch tube causing all kinds of problems. These are standard wear items so if yours it a little long in the tooth it may be time for a fresh one.
Along with the accelerator cable, this is another nice piece for your travel bag. Buy one and get a spare so you're never stranded again.
