1998 Ml320
This can"t be good

After some research about the 722.6 transmission I decided to change the AT Adapter Plug (13 pin connector) in my 98 ml320. I watched several videos of plugs getting changed, read several write-ups on the simple procedure. 1. Car supported on jack stands. 2. Wiring plug detached and pulled out. 3. 7mm bolt in center of AT Plug loosened. 4. Pull on plug to remove. Pull harder. Pull again---gee, those mechanics on YouTube just tugged them right out easily. 5. Re-loosen center screw. 6. Ratchet for 60 minutes. 7. Borrow camera scope and look inside old plug to find 8/13 pins bent by fumble fingered home mechanic who missed the center bolt on the first try and mangled them so they hold the old plug firmly in place. 8. Use long, thin screwdriver to attempt to straighten bent pins. 9. Successfully straighten 7, then begin to swear after snapping off the last pin. ONE OF THE PINS HAVE SNAPPED OFF!!


Any suggestions on my next step? I'm done in at the moment

Sounds like fun. Next step is go on ebay buy urself new conductor plate with a gasket and filter and plug, it all comes together. get yourself about 5 quarts of trany fluid and replace it all. you have to get the oil at the dealer $25 a bottle. I just did mine because it didn't shift up from a first gear. Will try to put in a link here for the part i got and a youtube video how to. It took me about 2 hours to do it all but i took my time, It was hard to get the plate down from the trany because it was kinda heavy, with 1 hand, laying under the car, and put in a new plug back in because o rings were new, so what i did was put some grease on them and plug slipped in. Check engine light was on.So had to get me a mb2 comp shut it off, that i had to get it on ebay too to shut it off, because my regular obd 2 couldnt do it.

Hope it will work for you

If any of the pins, and in your case 8, were previously bent, you would not be able to operate the vehicle.

Then why was it necessary to let us know.

Mea Culpa. In most of the other forums which I have been a part of, people share such things in the manner of participating in a community of people interested in some similar thing. My sincere apologies for wasting your time, and thanks for your help.
