I'm not sure what the problem is but maybe someone else can point me in the right direction..
My 05 G56 dually has 29,000mi on it and I have been running the tripple dog on the performance setting for 5,000mi..
Within the last 1,000mi the trans has acted up..
In gear and foot off the clutch there is a rather loud sweak/chirp noise that goes away as soon as you push the clutch in... Taking off from a stop is a little jerky now... And all gears seem to be more notchy to engage...
It does not seem to slip under heavy throttle.
Do I need a new clutch?
