Question:
ATF Choices for a Harley-Davidson FLHT Primary
I have been told that many Harley owners use Type F (Ford) ATF in their primaries, for one thing to make it easier to find neutral. I have some Mobil 1 Synthetic ATF Multi-Vehicle Formula that I was thinking about putting in my FLHT primary, but the back label states that it's not recommended for Type F applications. I don't want to put it in my primary if it has a lot of friction modifiers in it because I don't want to cause clutch slippage. What are your thoughts on using this ATF in a Harley primary? Thanks.

Answer:
Although an ATF may work, we suggest shying away from using it due to the low viscosity of ATFs and the possibility of premature chain wear and/or noise. We recommend Mobil 1 Racing 4T 10W-40 for Harley primary transfer cases. Alternatively, one could go with Mobil 1 V-Twin 20W-50.
