I want to change the fluid of my gearbox but since I dont have a professional garage at home I was woundering if this can be done only by putting the front wheels on a ramp?

Where can I find the plugs for draining the old oil and filling the new one?
Both for the 4x4 MT75 gearbox as also for the tranfer box please.

 

Not really mate cos if the front ends up in the air you won't get a true oil level

 

Its easy to do on the floor matey if you have a good look at the side of the box you will see the drain and fill bungs.
