So I have a 96 Geo Tracker 5speed manual 4x4. I bought it from my uncle who said he had just bought a brand new clutch. However the vehicle when started will only shift into reverse. It won't shift into any other gear. If I start it with the gear in first the car doesn't lurch forward or seem to do anything abnormal, except once I shift to neutral I am unable to shift to any other gears except reverse again. When the vehicle is off I have no problem shifting to all gears. I don't have the slightest clue what to check. Any feedback could be very helpful.
