Miles--

It's kind of tricky filling the tranny and differential. I made up a filling device by attaching a funnel to about 5' of plastic hose. I run the hose from the engine compartment down to the tranny, and pour the ATF (or oil) in the funnel. On the differential, you can run the hose from the top of a rear wheel down to the differential.

You can "pump" the oil into the tranny and differential, but it usually makes quite a mess.
