Do you have a manual or auto?
The filler plug for the manual box is located on the pasenger side (from memory) on the gearbox iteself so you'll need an oil pump of sorts.
If you pour oil down the dipstick for a non auto you'll put gearbox oil in the engine.
If you do have an auto you can put oil down the dipstick but it will take hours!
Cheers,
