Factory service recommendation is to change the transmission fluid every 30K miles.
Got an F-150 and 30K miles also. Somehow, I think this is revenue for the dealer. They charge $159. Other vehicles I’ve had ALWAYs have hit 100k miles without anything but topping off, if at all, with the right fluid. I don’t think I’m going to do this. I’ll wait until maybe 75K if at all.
