First question - what kind of transmission do you have?
Do not use gear oil. For many years now, all Rangers, automatic or manual, have used ATF although they use two diifferent types
of ATF in newer Rangers.
Your owners manual gives fluid specs and capacities. It also came bundled with a Scheduled Maintenance Guide that gives change intervals that vary depending on how you use your truck - see the section titled "Special Operating Conditions". If you don't have these books, you can usually find them on eBay or look it up online.
General 2001 Ranger recommended change intervals:
Auto trans (Normal street use): 150,000 miles
Auto trans (Special Operating Conditions): 30,000 miles
Manual trans: 60,000 miles
(Mercon and Mercon V are not interchangeable and should never be mixed.)
How about adding a short signature that tells us a few key things about your truck? Year, model, engine, trans, drive, etc.
