Rookielexus,
Welcome, if you do not have prior vehicle service records I would recommend changing the engine oil and filter, transmission pan service to insure the transmission is in good condition and then perform a transmission fluid exchange. This is an easy process to complete if you have mechanical skills and do your own service work. If not any competent shop should be able to complete for you. I would also recommend at some point changing the fluids in the differential.
The engine holds 5-quarts of 5W-30 or 0W-30 oil; the oil filter is an AMSOIL EaO57 or WIX 51348; the air filter is a WIX 46673; the cabin air filter is a WIX 24905; the transmission will hold approximately 4-quarts if you drain the pan only and approximately 10-quarts to exchange the entire system; the rear differential holds 1.9 pints of 75W-90 or 80W-90 GL-5 gear oil; and the transfer case holds 1.9 pints of 75W-90 or 80W-90 GL-5 gear oil; the cooling system hold 10 quarts of coolant.
