Used Dino 80w90 in trans and diff on my truck. The diff oil didn't look all that terrible, but the stuff that came out of the trans was NASTY. I drove the truck around for several miles before the change but trans was barely warm. Diff was still cold and of course I used the extractor on the diff since no drain plug. Took forever but I adjusted the brakes while the molasses crept through the hose. Next time I'll take it out on the freeway to get it good and hot before doing this. Got the radiator changed out yesterday. I think this baby is ready for a trip to the dump or Home Depot or even cruise night again haha!
After changing the diff and trans oils I took a nice cruise down around the beach and stuff. Shifting felt much better but I only went a few miles. Like I said the trans oil was very bad looking. Next real drive I'll know if there was a real difference in shift quality. Not expecting perfection out of an old np435 anyway.
