I sent the valvebody to get rebuild by and independent rebuilder. Do I need to do the relearn as well?

Yes. You are going to have new tolerances and resistance in the valve body. Resetting Adaptations and doing at least some of the "learn" driving procedure will minimize wear and any jerkiness you might get while your TCU learns the new tolerances.

So....I don't know if I missed something but I got everything back together and put fluid in to begin the fill procedure......but the car won't start.
I push the button and everything turns on as if its going to start but nothing. Has anyone experienced this before? Car fired up with no problem prior to the service. I'm also having a hell of a time trying to get these adaptions reset, software isn't acting right. |

The code I pulled is P0706 (pending code)....
I was able to get the INPA software connected and reset the adaptions. From what I can find this code has something to do with the gear selection. I don't know what I missed but its taking this thread off track, my apologies. I'm going to have to do somemore homework, I feel this is something simple that I moved on the valve body. I also never did opened the valve body, only changed the solenoids and seals. |

https://autoservicecosts.com/obd2-codes/p0706/ The good news is that it is a generic code, and I suspect it is what is keeping the car from starting. Here is why. From that page: "The Transmission Range Sensor is also sometimes called Park/Neutral switch or Safety switch. It communicates with the vehicle’s transmission control module and PCM, and is attached to the manual valve of transmission." It also indicates this for a possible fault which I think it helpful: "Faulty manual shift valve linkage". Here's why. Look at this doc and pics on page 6. http://www.thectsc.com/images/pdf/th...eplacement.pdf Did you verify your selector valve alignment was correct? I have an M-shift and I suspect you do as well, and you have to make sure it lines up correctly as you install the bolts (the lever should have been left in Park and you align the rod, lever, and the plastic piece when you bolt up the valve body). I suspect if this isn't correct, the car won't know you are in Park...which I believe is what the code is saying, if I am reading it correctly. Unfortunately, you will have to drain and remove the pan to check. I bought a new plastic gas container and used it for reclaiming my ATF when I was dealing with my issue so it would l be a less expensive decision to drain and refill. HTH and YMMV.

You guys are seriously a life saver! That was the problem and it was clear as day once I took the pan off.
I simply loosened the valve body bolts and slide the rod were it needed to be, put everything back together and filled it up. Andy- Once you posted that link and I read page 6 I knew I screwed up cause I didn't even pay attention to it, nor did any DIY I studied showed emphasis on aligning that rod to the linkage. Thank you again |

Just reporting back guys....
Trans still acting up but now I've been able to isolate it to a single code of P17E8 which is exactly where I'm experiencing trouble....3-4 gears So I have a few options.... - rebuild the valve body with the Sonnax Kit and hope that fixes it - buy a used trans and install it myself - Just take it to trans shop and have it rebuilt I'm not new to BMW's and repair work but I'm fairly new to these E90s. You guys may feel with confidence that the problem is in the valve body and my optimism, time and wallet will gladly believe that. Please let me know yor thoughts. |

The most notable thing is the shift from 3-4, it flares up and shifts hard, then off course it goes into limp mode. Sometimes in 3rd it feels like the pressure to the cluthes is intermittent causing it to jerk.
It regards to the repairs done, I replaced all the soleniods, foam piece, pan w/filter and of course the fluid. It should also be noted that the old fluid, which I was told never was changed, looked like Yoohoo chocolate milk (sorry for the reference but its the best comparison). For me it would make sense for the valve body to need rebuilding with the Sonnax kit as the other gears shift fine and grab like they should. |

I certainly agree its something in the valvebody and I've already ordered everything to put the Sonnax kit in.
I'm going to have to greatly study your DIY and make sure I understand everything clearly. |

Anyone have a list of all ZF codes and what they mean? Seems difficult to find on the interwebs, for some reason...trying to find out what a 00511B is. Thx.

I don't have the ZF code listing. I would contact xHP and see if they might have something?
