It was not a hot trans. Truck was parked on street for two hours. I went to back up on level and had no reverse. Pulled forward and took it around block. Had fluid changed twice during last season over hot trans issues. Fluid had no metal on either fluid changes. The cooler was not blocked. I'm hoping its transfer case The only reverse power had under load or empty was in 4low on level or backing up grade.
