Yet another Transmission Issue - 2005 X5 4.4

[zeroboot]

I have what looks like is a common issue based on the other posts on this and other forums. This has to do with the 'lurch' and 'shudder' that many people seem to be experiencing...

Here are the symptoms:

-During a cold start (cold being the engine is cold and its -10C or colder), from a starting position when shifting from 1st to 2nd, there is a noticeable pause, engine revs high, and then a very hard shift into 2nd. This will happen consistently but tends to go away as the transmission warms up.

-When driving at various speeds (slow, fast, doesnt seem to matter) there is a subtle but noticeable shudder, almost feels like the engine has a slight misfire, but there are no other symptoms to indicate that is the issue. It feels like the transmission is not quite fully engaged (cant think of a better word).

-From a rolling stop, and then acceleration, the transmission downshifts, there is a high rev, and then the transmission upshifts, and the common 'bang' into gear, which often feels like the vehicle was rear-ended.

-when driving at a low speed (anything under about 50km/h), I pump the gas several times. this causes the transmission to shift and I get a high rev, and then a pause and the transmission re-engages (similar issue to the lurch). I can reproduce this fairly consistently.

I recently had the tranny gasket and sealing sleeve replaced and 1 litre of fluid added to top up (M1375.4). This was done by the dealer under CPO, after finally convincing them that this should be covered - but not before I decided to go and have a 'long talk' with a service manager and BMW HQ.

I still have 50k or 1 year of CPO left. Should I be pushing this issue with BMW to replace under warranty or is it possible that this thing will last? I have previously had them do the tranny re-program, which obviously doesnt fix the underlying issue.

What would be the best way to build a case to show BMW that the transmission should be at least serviced if not replaced?

thanks,

You can't build a case for it being serviced, as that is against BMW's recommendations. You can work to convince them that it is abnormal and requires replacement.

My 05 4.4 is at the dealer now for similar issues. I just get the 1st gear bang..then everything works fine...They changed the fluid and re booted under BMws instructions...my guess is ....not fixed.

Start pushing for a transmission replacement now. They're so expensive and it sounds like you have serious issues. You are driving the "ultimate driving machine". If it's anything less than ultimate, why the hell wouldn't it be covered with CPO? Unfortunately, shops seem to love to be assholes when it comes to major repairs. In these situatons, the squeaky wheel gets the grease. Do not tolerate a shitty transmission, when you have warranty. That's what it's for. You could even try a different dealer in town, or a neighbor town. Don't give up. Some firm complaining now, WILL save you thousands later.

Sounds like you have more issues than the common "lurch" problem. I have the slam coming out of a rolling stop but none of your other symptoms. It drives perfectly fine otherwise.
