Dangerous to drive with. Causes problems when merging onto freeway.

If you accelerate hard and let off, it will stick up at 4,000-5,000 rpm for no obvious reason. Then lurch its way back up through the gears. Or if you accelerate hard briefly, you get no power because it won't kick down, then the transmission (after you let off) decides to down shift, so you once again are stuck at high RPM's, while it lurches its way back through the gears. The only way to get it to shift properly is to floor it.
