Have you tried this?

-Drive FORWARD (Not reverse, so make sure you are out of your garage before you attempt to do the transmission reset)

Do this every other month or when the transmission start slamming again.

I heard that the above procedure resets the throttle adaptation not the transmission adaptation. Can someone please confirm one way or the other?

People claim it makes a difference somehow and somewhere but it doesn't reset the transmissions adaptations.

But I will try it again today and report back

You think our X5's are bad, you should ride in my Acura! Accelerating from a rolling stop produces a crazy slam. Almost like that of a broken engine mount. My X5 does it occasionally, but not nearly as bad or as often as the Acura.

I'm with you. My 2000 4.4i drove without a single problem for six months. Then the transmission began to act up even though my driving habits remained the same. I took it to my indy and he replaced the valve body and the problem disappeared.

I'm surprised to see after so many years this is an issue for which there appears to be no consistent solution. I would have thought the underlying cause would have been diagnosed by now.

for me it seems to be a driving style thing, i have an 05 3.0d and if i come to a sharp stop, as in peak hour traffic it will intermittently slam, from what i have experienced it seems as though the trans is hanging onto 2nd gear, thinking that the car is going to want to speed back up, once it realises its stopped then it selects 1st gear with the accompanying hard down shift, what i do is either slip it into neutral just as i roll to a halt or alternatively put the stick in sports mode, but this can be a pain in stop start motoring as it hangs on to each gear to long

as i said for me its a driving style thing,

Having the latest software update done in a week so I will report back

I think it's more than a driving style. As I stated earlier I drove my X5 without any changes to my driving style and it started to exhibit this behavior after six months. IMO there's an underlying issue which driving style can minimize. But, IMO, it's a bandaid and not a cure.

could this problem simple be a auto tranny thing?

Stopped into my local dealer and talked with my service tech. I am experiencing the slight bump when the transmission shifts from 2-1 upon stopping (I can control it if I ease off the brake just before the car comes to a complete stop). I would like to have the updated software program, but...

Dealer wants $180 to reprogram...Is it worth it? Would an Indy be able to perform the same job at a fraction of the cost BMW wants?
