Transmission Oil Conundrum
2001 Ford Excursion 2WD 4R100 212000 miles
I just purchased this truck and want to change the fluid.
While there are some service records that came with the truck, there are none that indicate the type of fluid currently in the transmission.
The question is:
Seeing as Merc.V and DexIII/Merc are incompatible, is a standard pan/TC drain & filter change enough when switching fluids.
Is it really necessary to switch to a MercV fluid? What is best for an older transmission that has had an easy life, but will be doing some towing now?
