If your clutch is trying to tell you something, you won't get far by ignoring it, so it’s best to heed the warning signs.  One of the most common signs is a "slipping" clutch.  A number of things can cause this, from a clutch that’s worn out to an oil leak.  Although it's possible that your clutch needs to be replaced when it starts to slip or fall out of gear, there's also a chance that you only need a relatively minor repair.  In either case, don't wait.   Call Tommy’s for assistance.
