What transmission oil does a 1991 Ford Laser manual take and where do i put it?

A 1991 Ford Laser with a manual transmission typically requires API GL-4 or GL-5 gear oil, commonly 75W-90 or 80W-90 viscosity. To add the transmission oil, locate the fill plug on the side of the transmission case, remove it, and use a funnel to pour in the oil until it reaches the level of the fill hole. Always consult the owner's manual for specific recommendations and capacity.
