So I have a 2003 Prrotege5 with a 5 speed manual. Had the thing for 3 monthes, it has just over 101,000 KMs and yesterday when I was driving it normally I went to shift to third it grinded (3rd has grinded since i got the car, only doesn't if you wait in neutral between gears or if the car is cold) but when I let off the clutch it was in neutral so the shifter was in gear but the transmission wasn't. Then I pulled the shifter to neutral and it was in 4th and it wouldn't go into any other gear. Got it home and now it will go into 1st like normal and half into 4th which makes neutral 4th gear but nothing else... im guessing a full transmission replacement?
