What you are describing sounds a lot like what mine does under hard acceleration. But when mine does this it's actually cycling power to the front wheels on and off rather quickly, like it thinks the back tires are slipping (that's not gonna happen) I can see the TOD bars flash full and back down over and over and feel the surging that coincides. I've heard other owners mention this after adding larger or more aggressive tires. I have 33 inch MT tires and that's when I noticed it starting. It hasn't bothered me enough to worry about fixing it. I don't often leave a stop under full throttle...
To see if yours is doing what mine is, just watch the TOD graph and see if fills up when it surges.

Sometimes, when accelerating rapidly from a standing start, especially if on a slight uphill grade, the transmission will appear to slip and then literally buck (rear wheels only as far as I can tell) when engaging. It may do this repeatedly when accelerating through 1st and 2nd. It may also do this on a bumpy road, for instance, when on a road that seems to have ridges on it every so often. I'm guessing a problem with the clutch pack but it is hard to tell how bad it may be. I can prevent it from occurring simply by accelerating more gradually.

One transmission shop said $2500 to $3000 for a new "kit" without even getting into it. Has anyone else experienced this and, if so, how did you correct it? This is my second VX and I never had this problem with the first one. Thanks.
