Can you top-off the transmission oil without drain & refill

[Paul Giganti]

My transmission oil is fairly fresh, but I just did a rear brake job and lost a bit of oil from the rear wheel bearings. Is there a way to just top-off the oil in the transmission without having to completely drain and refill it? I can't find that info anywhere in the manual.

If it was "a bit" like a sip off your coffee in the morning, forget it; gears in a 'box only need a rotating bath in the lube at the bottom.
But you can 'refill' simply by taking the plug out of the side and adding just enough gear lube to not quite leak out of there. And when you add enough to leak out, as we all do, just put the plug back in and clean up.

When you do it, make sure you have the car's weight on the wheels. If the car is on jack stands with the axles drooping, the oil level will appear to be low and you'll end up with too much oil if you fill it to the bottom of the filler hole.
