I’m fixing to head to the auto parts store ... I’m not sure what type of oil is in my truck and I can’t find the maintenance book for it.. I do a lot of shifting going through these rough dirt roads..

in that case, I would have just put 80/90 dyno oil (some decent name-brand or Walmart super-tech) in it and called it a day. Just be sure to replace the oil every 2 years or 250k miles and it should be fine.
