Update, found a dealer 2 hours away guy got me front and rear trans speed sensors. To my surprise they came in around three days. I drove, picked them up and installed today and boom. No TOD light anymore and TOD and 4wd low work as normal. Pretty tricky getting them back in as they came with pins that had to be inserted into the bulk chassis wire harness connector and remove the bad wire to the faulty sensors. One word for anyone attempting this repair...PATIENCE. Thanks for all the suggestions and hopefully I can remain breakdown free.
