I have a 2007 LS with the 5 speed trans in it and over the last few month I have been having a stutter on take off. It only seems to happen from a dead stop and seems to be worse on really cold mornings. The clutch doesn't seem to slip under heavy acceleration but i get a noticeable stutter on take off. Any one got any ideas on this one it has me stumped since the clutch seems to be fine other wise?
