ive had my 08 gt for almost a month now ive got 1k miles on it....i bought it new and i never noticed it but i was driving from a stop and i noticed that when i go from first to second normal driving it makes that bump sound..... ive read other post's before about the play in the stock 2 piece driveshaft and thought i could have the same problem...... and also when im going for instance thru a parking lot in first gear doing maybe 5 mph when i go to press the clutch in to stop it makes that bump?......do i have the same problem?
