Good day all!!
I finally got a day off to look into the control module that connects to the valve body in our transmissions... I was interested to find out there is actually a computer chip in that black housing by Bosch...
***Additionally interesting to find out that the one in my 04 X5 has a 03-09-15 date on it
(Found out this is YY-MM-DD not the American MM-DD-YY)... I googled the part number on the computer box (1267017164) and there is a company in Bulgaria that fixes them... I didn't see a cost involved with this repair... I can imagine it would be more than the replacement trans I'm considering...
This is the deal with these! They are not meant to be pulled apart... ZF or Bosch did a good job making it very difficult to disassemble...
First things first... This seal did come off of the filter and stayed in the trans... Keep this in mind!
The new one was very difficult to get out... I pulled it just enough to get the valve body out...
Interesting!!!
Computer part number you can look up... There is also a video you can watch if you google the part number...
I would have been able to get the circuit run completely free from the plastic holder if it wasn't for this speed sensor of some sort...
This goes under the computer chip housing...
And the reason it was so difficult to get apart... There were two of these for each solenoid... This side was a bit easier than the other... In most cases there is a tab that moves and unlocks the connection... Not so here... You have to move the housing away from the tab... I don't recommend yous pull this apart... Nothing in there to solder back together or replace to fix the issues this thing causes... Unfortunately, as of this moment, I do not know how to get a replacement part without sending out the original to "be repaired" by someone...
I cleaned this really well and I'm gonna see what happens when I reinstall it... If I get the same trans range sensor error, I'm going to get another valve body if it has this included....
Cheers for now all!!!
