Depends on which trans you have. Some of the 5 speeds take gear oil and some take atf.
Look in the tech library to figure out what trans you have. The M5OD takes Mercon ATF.

If this is for the '93 in your profile, it's Mercon ATF regardless of what trans you got (be sure it's "Mercon" (or Mercon/Dextron III) and not "Mercon V" or any variant like that, the 5-speeds don't shift well on Mercon V unless they call for it ('98up IIRC)).
Edit, takes about 2.75 qts.

the manuals call for Mercron V on any M50D transmissioin.....the only difference on the internals in the M50D-R1 that was installed in the '00 and older Rangers and the M50D-R1HD that was installed in the '01+ Rangers is the gearing....

yup....I know they do, but there was a discussion on here not too long ago about this, and several trans people said it isn't a good idea. I tried it anyways, and had "shift quality problems" (grinding going into any gear unless I either floated it or double clutched it). This went away after I started to use plain Mercon again.

Yeppp...
I thought I was seeing things too... ATF in a manual. My 1964 MGB used 20w-50... thought the Ranger would be similar.
What should I put in the "pumpkin" aka dif?
I have 230,000 miles ... my mechanic said to "let it go" but I plan on a long trip to the North-woods this summer pullling my homemade sailboat (less than 1200 #'s)

Umm, no...
Go look at the manuals for real (I just went and did myself), they all call for "Mercon" (Ford spec XT-2-QDX) in manual transmissions all the way up until this year's model (2008). The AUTOS started calling for Merc V in '97 (XT-5-QM).

Ford doesn't license regular Mercon anymore and they say that Mercon V is now suitable for all applications that used to call for regular Mercon.

Why are people having problems in their older transmissions that clear up when they put regular Mercon in then?
My buddy's truck has been having similar shifting issues too. I suspect it's because of having V in it (I'll know for sure if he ever gets off his ass and puts what's supposed to be in there, in there).

ive got V in mine and i havnt noticed any degradation in shift quality...
not saying V doesnt cause the issue...just saying it doesnt cause it in all instances.

This is true that Ford states Mercon V is the replacement fluid for Mercon

Why did they separately recommend Mercon for the M5ODs, and Mercon V for the Autos for 11 years then if they're the same (if V supposedly replaces non-V)? Something is very weird here 
Guess I'll have to coax my friend over here and see if changing the fluid clears his issue up (balks at going into first gear right away, but if you sit with the clutch in for 5 seconds or more (letting the clutch disc spin down), then it slips right into gear no problem, plus it wants to "chunk" sometimes when shifting between the other gears).
I won't be experimenting with V in mine.
