Any of the Ford dealers can tell you this. Your owners manual also has all fluid levels for the vehicle. Ask where you have your truck serviced. Look at the linked ads below this answer.
look in your owners manual.
there is a plug in the side of the transmission. Remove the plug, the fluid should be up to the hole just before running out.
mercon, not merconV matters not if its auto or manual. They all use the same
It is important to use the right type of transmission fluid in a car. The 1997 F350 Diesel uses Mercon III transmission fluid.
According to the 2000 Ford F-350 Owner Guide : 5 speed manual transmission ( 3.4 U.S. quarts of synthetic MERCON automatic transmission fluid ) 6 speed manual ( 5.8 quarts of Motorcraft MERCON ATF )
According to the owners manual - transfer case fluid - Motorcraft MERCON ATF ( automatic transmission fluid )
The amount of transmission fluid that a Ford F350 will hold depends on the size of the transmission. The average is about 19.2 quarts of transmission fluid. The specs can be checked in stores during purchase. Over filling will cause problems with shifting.
The 1987 Ford F3 50 transmission fluid capacity is 8.3 quarts. You can check the transmission fluid level with the transmission dipstick.
mercon sp
If you are talking about the transfer case on the transmission....it would be any brand of 90 weight oil.
if it is an automatic look under the hood near the back and locate the transmission dip stick. Remove the dipstick and put a funnel in that's where the fluid goes. Standard transmission has gear oil and is completely differant.
The dipstick should be on the passenger side near the firewall, it should have a yellow handle that says trans oil.
