Wow, amazing and congrats yet again What a voyage! You've given that X5 a new lease of life and it's just as good as new! I crown you the X5 guru Now, do you think the trans issue was a result of lack of oil change and thus excessive dirt? BMW recommends trans oil and filter change every 100k miles, I think.

Thanks!! Oddly, I am not sure I deserve that honor just yet... I think I jumped the gun on the fix... I'm not sure what the issue is, but the colder it is outside, the better... It's not fixed yet...

So, to recap... Last night I put about 8.5 liters of new LG6 in the trans... Got it up to temp running up and down the road in my area... Nice and warm with no issues... Excited about taking it to work today...

On the way in at 0545 hrs this morning, I got about half way to work (on the interstate) and got the trans fail safe again... It must have stayed in 5th gear for the rest of the trip to work... Which was a question I had about the fail safe program... Would it drop to 3rd regardless OR use the trans speed to figure out the best gear to use at the time of failure... It was the latter...

So, on the way home at 1430, failsafe hit almost before I got out of the parking lot... It didn't leave third gear the whole way home... It did take a while on the back roads...

So, now I have to reevaluate things... Where to start?! The other bad news is that I have the exhaust cam over advance issue again...

Time to hook up the computer...

Cheers for now!!

Good day all!!

I found out that I have a trans gear selection wire that is not changing states once warm... Once I get to Drive, it faults the computer out...









Okay, I looked them up... The problem is that L1 is always "ON" and I know "D" should only have L4 "ON"...

This first one should be PARK... I pull actual readings from the x5 when it was working...



This second one is Reverse...



And this one is Neutral...



This one is Drive in a faulted state... Only L4 should be ON...



So, I guess I get to pull the pan again and take some readings... May have a chaffed wire... This is gonna be that fun gremlin to find...

Will keep yous posted...

Since I will be needing the wiring diagram to figure this part out, I figure I will add this info I got from WPOLL on a different thread... THANKS WPOLL!!!

This site will tell you where any electrical component is located: -

WDS BMW Wiring Diagram System - English

You'll need Java and Adobe SVG viewer but it's an amazing resource, with full component descriptions, locations and full circuit diagrams!
Oh, one more thing... I can't get the computer to talk to ANY module except the motor and trans, including the Air Suspension module... Frustrating!!!

Cheers for now!!

Happy 4th everyone!!!

I sat in the X5 until it faulted out... I watched the temp and wire activations... I did find out that it faults out quicker if I select out of Drive then back in Drive... It only faulted twice while staying in Drive... The temp hovered around 103 C... It did not fault out... Even moving from D to N then back to D... I turned on the A/C... Temp climbed up to about 107 C... Moved from D to N and back to D... Wire L1 stayed in the "ON" state... It did not clear up until the temp dropped down to about 93 C...

I checked the pins on the connector... All were locked in the correct position... I remember reading something about the connector pins getting pushed back into the connector... Not the case here...

So, this isn't fun anymore... I really want to get the black circuit board connection unit that has the gear selection module integrated into it, but I can't just get that part... I have to get the whole valve body...

Or tear apart mine and hope I don't destroy it beyond use...

Off to see fireworks!! Everyone have a safe holiday!!!

Cheers for now!!

Keep the faith! You'll figure it out.

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!!!

Okay, I will lose cool points for what I am about to say as many of you won't believe me... I honestly am questioning how this happened!!

Somehow, in the past day, someone or something has decided to walk off with 13 of my pan bolts, including two of the four new ones I just got... I have eight (six old and two new)... The rest are gone!! I left all of them under the truck in a pile...

Honestly, has this happened to anyone else?!

Cheers all!!!

That is actually a thought that had crossed my mind... It ended up being a random turn of events that put the missing bolts UNDER the drain lid I was using... Obviously, I checked in the drain pan, but moving it around on the floor to inspect where the pan was didn't leave any bolt in its wake... It was only when I went to filter the fluid for reuse that the missing bolts showed themselves... Not sure how or why they ended up there... Don't care! The good part is that I found them and don't have to wait for new ones to arrive...

On to the trans filling!!

Cheers all!!!

Regarding the exhaust cam over advance issue, you may want to have a look at these posts, essentially a DME Ram Backup via toolset32 (Select d_motor.grp which will bring up the correct .prg file for your DME - scroll down the list of jobs - double click "RAM_backup"):
