Ok guys - gotterdone tonite - transmission plug adaptor changed. No frostbite either.
Here are a couple of more tips in case someone searchs for this.
I dont have ramps so I jacked up the right front corner about 4 inches to provide space for my wide body. I also pumped out about 1 quart of ATF via the fill tube just to make sure there wasnt a flood when I pulled out the old plug. Dont know how necessary that was, but I wanted to keep track of all the ATF since I dont have a dipstick. There was no leakage when I pulled out the old plug.
There is a small heat shield over the plug held on by two 10mm bolts. Actually you only need to remove the bottom bolt. The top bolt is holding a spring clip that slips over the heat shield. Of course I didnt discover that until I took out both bolts. Top one is a pain to reinstall so leave it alone.
The electrical plug is locked into the adaptor by a quarter turn ring with a tab for leverage. The old ring was really stuck on mine. I couldnt budge it by hand so I finally got a small vice grip on it for more leverage. Thought it was going to snap off but it finally let loose.
There is a 7mm locking bolt inside the adaptor that has to be backed out before the plug adaptor will come out of the transmission. You cant see it unless you use a mirror, but if you know it there you can easily loosen it with a socket.
The new plug adaptor fits very tight due to the larger o-rings, so its a bit of a challenge to get seated in the transmission. Once you get it far enough in then you can tighten the 7mm bolt to finish pulling it in. Did I mention there is not much room to work with the exhaust system right next to the plug? You definately want to do this job with a cool exhaust.
Anyway it took me about 2 hours start to finish (1.5 hrs taking apart and 0.5 hrs back together
