Ive seen a couple of the 45RFE / 545RFE Transmissions go around 250,000 miles on the original ATF+4 and Filters (It has two filters). In both cases the diagnosis was pump failure.
I wonder if the transmissions would still be alive if the filters had been changed even with the original fluids.
Anyone want to suggest a fluid and filter change interval? Im only planning on doing partial changes (13 Pint Service Fill) not a flush.
Owner's Manual suggest 60,000 Miles for Severe Duty. Im thinking every 3 years (30,000-36,000 Miles) for Service Fill.
