enigma-2 Posted March 12 Author Report Share Posted March 12 Officially, Ford says it will last a lifetime. (Fords definition of lifetime is the warranty period.) After the local Ford/Lincoln service replaced my PTU, the service manager told me to change the fluid at 30k intervals. Nothing written in blood, if you pull a trailer, change each year. If not, figure 30k. Quote Link to comment Share on other sites More sharing options...
