You are in Florida. I would do the 75-140 which is similar to the baker recommended Spectro 75-140.doing trans service 75w-90 or 75w-140 :2thumbs:
also doing primary service do you order gasket or seals from big dog or is there somewhere else ?
If you have the o-rings then you are ok. I still have the original o-rings in mine since I purchased it in 04.thanks guys and how about the primary gaskets
