I have a 2000 Dodge Dakota with a 5.9 and 46re trany. I just got the truck, engine wasn't running.. got engine running went to drive it noticed only forward response from transmission. Checked fluid levels found low and slightly discolored. Dropped pan found small amount of metal but no snap ring pieces as read in threads before. Changed filter and fluid retested and still same issue any pointers on which direction I should go next?
