I have the same transmission problem, plus some slipping in 3rd. The dealer so far isnt much help because they cant "reproduce" it. It only happends in 5th gear, at low speed, usually between 20 and 40mph. My thinking is that it is in 5th geatr and its trying to downshift into 4th, but halfway through, it changes its mind. Dont know why they cant reproduce it. It only happends all the time when anybody in my family drives it.

that's great!
So how much did it cost you to replace the two struts?

If you mean your problem is really #2 (the tranny seemingly trying to find the correct gear), then yes. It's not really a problem, per se, in that BMW designed it that way to get max mileage.

You mentioned it happens every 2 secs or so at 1500 rpms ... this part does not happen to mine though.

Exactly. Mine does it when cruising steady at 60km/h (37.4 Mph). I know this and it's very noticeable because that's the most common speed limit and the regular cruising speed for the car. It feels like it's dropping a gear, but it doesn't. It's not hunting, which I understand as dropping and then changing up again. Slowing down a touch or speeding up a little cures it.
Very annoying that I have to be either slower or faster (A big No No here) than surrounding traffic.

I have heard this is common in the 7 series with the same transmission as well.

serbiasrt8: LOL i saw this vehicle posted for sale and was tempted to trade in mine and fly down to Cali to pick it up! Good job on the purchase! Congratulations!

Congratulations and welcome. I have noticed the transmission is a little jumpy sometimes, but love her anyways. Good luck with getting it straightened out.

Hey guys Thanx!
Well Chigga,i got the X before you!

The tranny issue is not a bug deal to me,and it's god to know that most of them have that problem.I don't lose sleep over it,because when do i ever really drive in highest gear at 1500rpms.

FYI to all you who followed this thread. Transmission lost 5th gear and failed soon after and required a rebuild. Rebuilder told me this issue is common with this transmission.
