Usually transmission noise, in the form of whining or howling emanates from the back axle, even though it might sound like it's coming from the gearbox. 4 speed synchro gearboxes can sometimes whine in the intermediate gears but, unless the bearings are damaged, usually by corrosion, the gearbox will be silent in top. Back axles tend to pick up noise in top and are usually vocal between 35 - 45 mph.
3 speed boxes are a completely different kettle of fish......
Worth checking for oil in both but don't overfill, otherwise you'll get soggy brakes and/or clutch!
