2008 X3 no reverse

I have a 2008 X3 that the reverse just went out on. Was working just before I tried to back it into my garage. Anyone have this happen or know what it could be? I did rev the engine up while in reverse and it would go to about 3500 rpm and would drop to about 1000 rpm.

Looks like a easy fix for someone that knows what they are doing. I hope thats it. Just had my tranny oil changed six months ago.

a good how to /tools and parts bavauto contact

a good blog info link for you .....call these folks in the am.....also.....remember that all the mechatronic / valve bodies do is operate fluid flow thru solenoids to save us manual shifts .....not much mystery there !......the valve bodies are easy to take out ....BUT ....BUT ....BUT ....if the bust shaft is your issue you may be able to swap it without taking down much stuff

homework

some good generic bmw 5 plus speed auto transmission valve body etc info in these




here's a 6 speed getting the zip solenoids....this may be your model ....or it may be the GM type 6 speed below



this is probably close to your transmission .....put the last seven of your VIN in realoem.com and check what you have in a 2008 x

http://www.realoem.com/bmw/enUS/show...diagId=24_1076


the GM 6 speed .....in bmw's, fords, Rangeys etc

good views of getting to the valve body

a pain just to swap a 20 buck rod ....but ensure you do the seals etc and swap oil and filter if poss if this is indeed the issue you have

Isn't this caused by shifting into reverse when the car is moving forwards, and vice versa?

materials failure

it's ben shown to be a very poor materials failure......an overlooked weak spot that has cost them beaucoup .....a sad part of engineering just like the ZF transmissions materials failures in the gear carriers and the newer transverse engined units

Can't get anyone to agree with this. I know it's going to be 500.00 just to look inside.

X3 is in the shop. Trans light came on and car went into limp mode. My Aamco trans. shop has it and they said they have done several of these. My regular guy couldn't get it in.

take no prisoners

don't let any of the shops spoof you ....these are mostly GM transmissions.....they are used in one form or another in beaucoup euro and usa vehicles ....and ....yes.... they don't use friction bands but there are trillions of them on the road....so ....prices for repair should not be out of line

Did you do a transmission pan drain, filter change which exchanges about 40% fluid or did the power flush by hooking the cooler lines to the Fluid exchanger machine which can get the old fluid from the Torque converter out as well?

Good news, aamco called and said it was the gear selector valve. They are going to replace all the other seals also.

Not sure if you understood my question. You mentioned you had transmission oil changed 6 months ago. What was the process used? drain pan and fill to level or Power flush using machine?

Based on other forum expertise, drain and fill to level is safer vs power flush to not dislodge any sludge if any into mechatronic components and risk blockage.

a good learning/outcome

well done.....it's good to see that a good transmission shop and not an expensive foreign stuff only operation can give others confidence in searching for lower cost/local options
