Well, I don't have any pics. Might take some when I change diff oil later on.
It's pretty straight forward.
Gearbox:
undo the upper refill nut on the gearbox located on the passenger side of the gearbox. You need to get under the car to do this. the nut might be evry tight so expect to use a breaker bar. It's one of those square type thingies on the nut.
The drain is on the underside of the gearbox. similar nut.
Do the fill nut first. Not very. nice to drain the box and then not mange to undo the fill nut.
After the oil has drained put the drain nut back in and refill the box from the fill nut place untill it comes out of the fill hole. I bought a cheap manual oil pump thingie so i could pump the oil in, but you could use a garden hose and let gravity work for you.
Rear diff:
same thing here but on the diff.
This is just taken from my memory. I'm sure someone will come along and make a better explaining post
