I have a 2003 5 speed GT and it's got about 91,000 miles on her now. I've noticed especially when she's cold, the shifts are kinda harsh not smooth... And when I get on her (Warmed up) the clutch feels different. About half the pedal is extremely easy to press, then feels normal after half in. I'm thinking about replacing the clutch, throw out bearing, and roller pivot bearing. But I'm not sure if that will be my problem. I've already replaced the fluid in both trans and rear not too long ago. I'm sorry if I'm not making too much sense, but it's hard for me to explain it. Any help is greatly appreciated! Thanks
