Find the fill plug on the top of the gearbox. if you cant find it follow the speedometer cable down to where it connects to the transmission; the fill plug will be near the cable.
Remove the fill plug.
Place a clean funnel in the fill hole and fill the gearbox with gear oil. Check your vehicle specifications to see how much is needed. Re-install the fill plug when done, hand-tighten and then torque the plug down with a socket wrench one turn
hope this helped
