07 4.8 trans fail after fluid/filter service

[Purplefade]

If it’s already bent I’m a try and straighten it with a long thin pair of needle nose pliers guy myself.

That said, the harness is one thing but the mech is super sensitive to static so I would rig up some form of ground strap for your needle nose before you go in for the fix.

Pins are real tight but if you’re careful enough you may be able to pinch any offending pins between the pliers and straighten them out, I wouldn’t “bend” them per say, I would “pinch” them straight if your pliers fit - assuming you find any bent.

Good luck

I think I recall seeing BMW sell pins for repairs... not sure about this connection tho. If you do need it (id try to 'correct' it as above) then look up some of the parts diagrams

I forgot i took a video checking the plug because i couldnt find a mirror at the moment. To me it looks OK but I think im going to pull the unit and the sleeve and reinstall everything if it checks out ok.

Hmm, wasn’t able to play the video. I’ll try again from my pc when I’m home this afternoon.

Question- did you change the sleeve in the trans body as well? Only asking as it’s possible if it is “loose” or not seated all the way that the harness won’t fully seat in the mech. It’s also possible, just asking, but are you sure you are getting a full turn on the harness when you’re re seating it?

I would hate to tear it down again before I triple checked everything...

Keep us posted.


Just re-read what LT posted above, if you’ve e had that plug in and out a few times (or more) now, he may be on to something. You may take a small pic and see if you can tighten up some of those clips in the harness socket and possibly improve the connection. - just thinking out load.

(Back in the day I used a very small jeweler screw driver to “pull in” the clips on the 20 pin connector under the hood of my 325, that’s kind of what I’m thinking towards here..)

Sorry about my code comment earlier. I was not paying attention. It is tough to tell because of the focus but your pins look to have some electrical grease on the tips of the pins. Almost like the female end is not sliding all the way down. Check the sleeve to make sure it is all the way seated in the housing. The locking mechanism can sometimes bend and appear to lock even if the sleeve is not all the way in.

After the sleeve is properly seated, push the locking mechanism to the locked position. Install the vehicle connector plug and check that the sleeve is properly seated. The locking ring gap should be between 2.5 to 3.0 mm.

Mecha is out and this is what both sides look like i see more pins on the mecha than on the harness side but it looks normal?

[Purplefade]

Looking at the harness it looks like you have one of the sleeves pushed back in the plug, bottom left?

looks like one of the female sockets has pushed up into the body, no??
