4.8i Jerky Transmission
 

Hi X5World, I have a 2008 4.8i and I have noticed that when starting on a hill from a dead stop or from a stop light in "D" my Transmission has a abrupt jerk as the early E60's did. It isn't noticable in "DS" but I don't drive want to drive in this mode all of the time. It is really un-comfortable as sometimes It is almost impossible to have a smooth start. A software update should be able to fix this but I was wondering if anyone else was having this issue.

Thank You.

Yes, my 2008 4.8i has a really rough transmission (as does our 2007 750Li). Sometimes it jerks/pulls so hard, it feels like whiplash. I've noticed that in general the transmission is rough, holds gears too long, downshifts almost violently when going up a steep grade and generally gives abrupt/rough gear changes. Besides from the non-heat resistant front windshield, the transmission is the most disappointing feature of my 4.8i.

i have the same problem. its not all the time.

So the problem being described here is directed when the car in on some kind of grade, correct? or does it occur on flat surfaces to?

Just curious. About what percent is this problem occuring? 100% of the time or much less frequent?

Is this different from the lag often talked about with the X5 transmission?

The problem happens on both surfaces, It is just more noticeable to me on a grade. If I had to guess, I would say that the percentage is about 60% of the time. Not all of the time, but still enough to notice.

I'm glad I'm not the only one having this problem, If the tranny was like the one in my E60 I would be extremely happy.

it seems like it happens when its on a hill.

it does not happen alot!!! once & a while.

I have a steep hilly road going up to my house, as I live about 1.5 miles up & into a large canyon/mountain area. My transmission does it EVERY time. I wish it was only 60% of the time! While going up the hill, I know the transmission must downshift for power, but the transmission will practically knock your teeth out. I also really dislike how it will hold the transmission in 2nd gear, at about 4500 RPM for a LONG time. Gee, wonder why I get 6mpg!!! :(

try goin to the dealer a software upgrade might solve the issue.

does anyone know if BMW has released a update yet?
I am going to take it to the dealer next weekend.
