2000 Grand Prix GT with 135,000 miles on it
Lost 4th gear about a month ago and now it shakes/slips at take off, especially when I hit the gas pedal a little hard. If I slowly hit the gas pedal and speed up at 20 mph this doesn't happen. Pressure problem? Also, I'm sure my clutch hub splines are gone...how hard would this be to replace or should I contact a mechanic?
