Damn..that wasn't it, car dropped into neutral and took me awhile to start and restarting numerous times. so far did resistor and adjusted hood closing sensors... next step, gear position sensor! One thing at a time..

damn knight, I think I will be following in your footsteps....

The resistor mod worked for mine for a little while then starting kicking me out of gear again after a few months. Just had the entire SMG pump replaced at my local dealer and so far no issues even in the extremely hot weather we've been having.

My car is in the same boat and I just had the salmon relay and hood sensors replaced with brand new ones.

Well we got a powertrain warranty that covers the transmission, engine and drivetrain.

Dropping it off at my local BMW guys' shop today. Hopefully they'll be able to tell me what codes come up. Last time it showed bad pump, pump fluid temp and/or gear position sensor. they cleared the codes and told me to drive it again.. sme thing happened. It takes me our of gear while driving.. i can tell the clutch is engaged because if I gas it, rpm doesn't go that high. Anyways... we'll see what happens after the re-diagnosis.

Is it happening in a certain gear?

If any of you have something else to drive and want to send me your pump, I'll try a partial rebuild/inspection. I've had one completely apart some time ago, but it looked perfect, solendoids tested fine, and in fact replacing the pump didn't fix the owner's problem, so that pump wasn't broken.
I cannot get the the pump gasket, only the surrounding o-rings, and there is a danger that it will tear when I pull the pump halves apart, so you shouldn't entertain this unless you have a firm "bad pump" diagnosis. The accumulator cannot be rebuilt, it is sealed.
I'll also pull the motor apart and test it; one in a recent post with pump failure (think the guy is in the UK) looked pretty bad with regards to brushes/commutator. That would be a simple fix as long as the armature wasn't fried.
I'll do this for whatever costs are which I'll document, and will turn it around in less than two weeks unless the armature is shot. I can't guarantee it will work, but should cost less than some of the other parts folks might throw at it.
PM me if interested.

I'm copying and pasting this here from the "SMG troubleshooting" thread.

It's completely relevant and hope it serves as "useful" you all of you:

All codes pointed to SMG pump failure - not enough pressure.. i get kicked into neutral - with accuator/gear position sensor next in line, we got the SMG replaced. HOWEVER ----> PowerTrain warranty came back and said "SMG pump denied!!!" Damnit man.

Guys - beware of these warranty companies... there's always fine print MAKE SURE THEY COVER SMG CARS, AND RELATED COMPONENTS - MOST OF THEM DO NOT!!!! My stupid company "NAC" (http://www.nacsolutions.com) only covered "internal parts of the transmission case - ONLY. that's total crap.

....so the dealer we bought it from dished out $1k bc they felt bad and wanted to help pay for pump replacement (total a bit over $3K parts & labor).. and we also canceled warranty and will be getting about $1300 back.. so we paid the rest "out of pocket".. i feel like an idiot.

NOW - it failed again, pressure is there now, shifts more distinctly, but i still got kicked out of gear and into neutral again after only about 10 mins of driving!!!

Having tech come out to diagnose the car AGAIN.. if it points to accuator/gps.. then that's another $900 in labor (i already have the part - used, bought it off of a forum member).

At this point, I'm going to see if dealer can pay for the additional repairs to make things right OR i just wanna resell it and move on with my life....

In this case, it's really no one's fault, dealer didn't know they bought a troubled car from auction, didn't drive it much to know anything else, sold to me, didn't act up during test drive, i didn't know... now i'm stuck dealing with it everyday.

I'm starting to lean more towards a Civic just so we can have a reliable car. sad isn't it????

PM me if you wanna know more - heck, text me if you want - 972-897-3094.. im sure a lot of you are going thru the same thing!

btw - i replaced salmon relay, smg pump, and did resistor mod. still no luck.... this is completed an F'd up situation for me. and this car was meant for my fiance - i feel so bad and responsible for picking the bad seed out of the bunch.

****Hey - if anyone wants to buy this car from us and work on it - I'm open to that, we'll lose money - but i just dont have time or money to deal with this anymore
