Transmission ?'s
So we have a 2003 F350 7.3 that has a transmission code of 9. Can someone tell me what transmission this would be as it needs a fluid and filter change. Also is Napa brand transmission filters good? and what fluid type should we use.
Thanks

If it’s the automatic then it has to be the only one offered for the 7.3 in ‘03, the 4R100. The original fluid called for was MERCON but that was later revised to MERCON V.
Personally I only use Motorcraft MERCON V and the Motorcraft filter on my 4R100. Any fluid that meets the MERCON V spec should be good though.

as far as I can tell, it’s 100% from factory that way. What will the nine represent?
