3. Car lurches forward from 2nd *to 1st and then again from 5th to 6th gear
4. Its as if the transmission is free wheeling before it finds a gear
5. Occasionally there is a low rumbling/vibrating/humming noise when at full acceleration experienced when overtaking on the freeway, 65 mph onwards when getting close to the redline.
6. When in slow moving traffic (25/35mph / 1,500 rpm / 40mpg) the transmission jerks approx every 15 seconds. Its feels like the brakes are being stabbed intermittently. None of the needles indicate any change whatsoever when this happens.

I took it into my dealership and they replaced the gearbox (remanufactured) free of charge. BMW North Scottsdale is AZ are the absolute best to deal with. I was just out of warranty and they had replaced he transfer case a couple of months prior so there was a sequence of event leading up the the gearbox replacement. They had tried everything including software updates before finally replacing.

I had done a tonne of research and I believe the 05 in particular suffered from this. Changing the gearbox erradicated all my problems
