If it'll make you feel any better I was doing a fluid change on my SRT6 and the upgrade changeout on the adapter plug. The first thing was the drain plug that takes a TINY LITTLE ALLEN WRENCH. I knew right away that plug was gonna wring out or the wrench was gonna break so I decided to just leave the drain plug alone, and let the pan down over a big catch container. That wasn't too bad, I dripped very little down my arms.
Then, I removed the connector from the adapter, so far so good. Then I tried to pull the adapter out of the transmission but it was stuck. I wiggled and wiggled it but it wouldn't come loose so I got the long nose vise grips and grabbed the edge of the adapter and really leaned on it till it popped. Yep I tore the whole outside of the adapter out and the center with the BOLT was still in there. I looked at the new adapter on the work bench and sure enough there was a small bolt in the center. I KNEW there was a screw that held it in there but at my age brain farts are a common occurance. Fortunately I didn't destroy any of the pins in the transmission and the new adapter went right in. DUH.
