Are any of you guys running CB's....or something that might be getting RF into the electrical system.....I know I had a problem with my Ham radio knocking off the cruise control in an older chevy van...

This may sound kinda far fetched but, NSBU Switch? Bad connection/bad wire at the NSBU Switch or TCM?

Everything your having trouble with needs a signal from the tranny. Thats where I'd start.

Try disconecting your ground cables and look to see if there is a crush washer, if there is do away with it,check positive cable also. Reconnect cables,making sure they are clean and tight.
