Do you still need wiring diagrams or diagnostic charts? if the vehicle is 03 or older I can probably find the info on my Alldata software... Sorry I don't have a newer version as its too Damn expensive.. (I have the commercial not the DIY version)...
I am happy to look up info for anyone that needs it...
My other suggestion when you get one of these "weird" issues is I can post it to
iATN.. I discontinued my paid membership when I got my new job as Mr. Mom but I can still post a help request if you are really stuck.
I'm not a transmission Guy at all, but I'm always looking to learn something new
