Revisiting this.
Trans had been slipping bad. I hammered down and never saw 3rd again and OD light flashing.
It's time. Although I don't think I'm building it myself, pretty sure I'm just doing a local rebuild. The shop I'm thinking of going with has a pretty darn good rep for 4R work.
Truck never tows, never pulls, just around town and 4x4 winter duty. Don't think I need a built trans. Local so if there are any issues it can be taken care of asap..
What is the benefit of a triple disc?
