Sorry, I can't help you, but I'd be interested in knowing if the fluid temp sensor is accessible/replaceable... if you happen to notice while you're working on yours.
I had a P0711 code for the temp sensor last week.
There are some tranny rebuild industry mags and websites that I came across in my research that might help, I'll try to find them again.
Actually, check this out http://juchems.com/ServiceManuals/vi...%20Control.pdf
I had printed a copy that was still on my coffee table...
There's a series of these pdf's. They're for 2011 Mustang, though. It's labelled 'in-vehicle repair'. Talks about putting petroleum jelly on certain bits when installing them so they stay in place.
