That's exactly the problem many '07 X3 drivers are having. When they drop the hammer to merge, either nothing happens at all, or the revs rise but it feels like the gearbox is in Neutral, never hooking up until 2 hours later. Such a disappointment with these new 6ATs. :confused:

My 2005 X5 4.4i had this same problem. It was so bad sometimes I thought someone had rear ended me. Dealer never could fix it. Traded it in for a 2008 X5 3.0si,no problems at all so far, shifts very nice.

Yes.


Seriously, I know that the BMW (Getrag or ZP?) transmissions are transmiting much more HP and torque, but how can Ford create a FWD transmission for an inexpensive $10,000 - $15,000 car like a Focus that shifts better than a BMW transmission on a $70,000 vehicle?

BMW should be embarassed and ashamed.

And if you don't believe me, go test drive a Ford Focus.

I totally believe you. Driven a lot of cars in the past and have never noticed a bad performing transmission until recently. Had a 2004 MB E320 that was absolutely horrible. It felt like the transmission didn't know what I wanted it to do. Heard the 7-speed put in after 2005 rectified this situation. Just hope my X5 won't be like that.

Does anyone know what transmission is being put into the X5's now?

My 05 4.4i had issues too. The rear end thing was corrected with a software upgrade but the transmission still seemed confused sometimes and didn't shift correctly.

No issues after 5400 miles with the 08 4.8i

its not just the transmission,its the x drive calculating before implementing reaction.

Not being dis respectful, but do you think thats cos you've learned how to drive it ?.. since I am wondering how much, the experiance of the auto box plays a part. I once had an Audi S6 Quattro that had a 'learning' box, and shifted according to how you used the accelerator. Quite un nerving at times,.. since when you floored it, there was no power if youd spent the last 10 miles wafting lightly along, it didnt think you were serious when you hit kick down, the trick was to stab the throttle once ,.. before you really needed the power... then next time you hit it.. it would go ...just a thought...:dunno:

I never had a problem with it so I didn't adjust how I drive to compensate. She's been smooth from day one.

It took me a bit to get use to the accelerator at first. It felt like I was giving throttle, the consumption gauge would react, but the truck didn't go anywhere.

But then I realized I like the sports mode, and learned to not be so hesitant to step on the gas. From what I've noticed, is that if you are driving with a fuel consumption concious right foot, that the tranny's performance is...well....weird. But if you hammer on it, with about a 4500+ shift point, the shifts are silky smooth. As will the truck move like it's suppose to. Alot like the ML, in which it's shifts are seamless.

In my experiences with the BMW's that I've either driven and/or owned, (4cyl, 6cyl, and now v8) none of them made any power till about 4500rpm...And it's increasingly become more pronounced with the VANOS and double VANOS, as these engines won't become efficient until Vanos has stepped in at the upper end of the engine...Having said that....slapping the tranny into tiptronic mode hammered down a 50-90mph curved road and not letting the rpms drop below 5K is an absolute riot. The engine is insanely responsive and the tranny is fun as it allows you time to tap the gas for a perfect rev match downshift. Pedals are also great for any heal/toe situations. Impressed the heck out of me at least. It's a little extreme for a soccer mom SAV, but it asked for it, and I wanted to see it's limits. And seriously, it will not let you get to that point. And although I may get trashed on a bit, but it's performance in the handling department, is moderately comparable to that of my e46 M...

[edit]oops, my ADD seems to have gotten the best of me. As per the OT, I don't find the tranny jerky at all. The tranny is a bit weird, but I've learned it's little quirks, like mashing the pedal for a downshift quickly, has a different reaction than slowly giving more gas.

There might be something in this .. may be it demands a heavy foot, not good for consumption, but maybe BMW decided if your buying a 4.8, that wasnt your priority anyway. I dont dont think I've driven mine enough yet to explore the 'mind' of the box yet. I agree that driving in shift mode is a hoot and can be controlled quite slickly though..
