UPDATE!!
Ok WELLLLLLLLL, good news and bad?
THE SHORT OF IT:
COACH VIBRATES WHEN ACCELERATING SOFTLY IN THIRD GEAR (30-50mph), FINE EVERYWHERE ELSE
COACH SEEMS TO SLIP, OR SPLIT-SECOND POWER-LOSS BETWEEN
THE FINER DETAILS (may or may not be necessary)
The coach has incredible power now, like when I first got it. Idles well, and runs in OD great, purrs like a kitten. Accelerating is somewhat rough. If I am hard on the throttle, that sort of slipping I mentioned comes back. It is not only audible but you also feel the coach pulling well and then sporadically 'slipping'.
When accelerating, the coach revs high as most v10s do im told. around 3000 rpm it starts to feel like you are hitting patches of ice, in the sense that you momentarily (for a quarter/half second) feel as if you lose that force which pulls you back in your seat somewhat. Difference is, on ice, when you slip the rpm go up. Here, the rpm still increase, but much slower. Once in overdrive, the problem disappears and the coach rides smooth. I should add that this occurs during hard acceleration.
During soft acceleration, in 1st or second it doesnt do this, drives just fine. In third, during soft acceleration the coach shakes. BADLY. Feels like its coming more from the rear end. It did this when we bought it, but it was very gentle and the coach quickly got over it so I thought it was just the old tires. Since then, I have had all 6 tires replaced with brand spanking new ones. The vibration is now immensely worse.
