I brought my car to an ASC certified tech for a King Cobra clutch upgrade. Once the job was done, the car wouldn't go into first, third, or fifth. After a little clutch cable adjustment it would go into everything except fifth and reverse. Can anyone help with this? He's telling me I need a new transmission or to have mine rebuilt, but I'm wondering if this is a fairly common problem that's easily fixed or something more serious like he's making it out to be. Thanks guys.
