OK... WHATEVER YOU DO DON'T POOR THE OIL THROUGHT THE GEARSTICK.. it doesn't work. the oil goes back into the transfer case... the transfer case has seperate oil to the actually gearbox.. use 1.8-2L of TRANS MATIC D OIL in the transfer case and 5L of 75w-90 gearbox oil. there are 2 drain plugs at the bottem of your gearbox.. one for the gearbox and the other for the transfer case. use a hand pump to pump the oil into the gearbox and transfer to make things easy. look in the DIY section at the R32 gearbox oil change.. its sort of the same thing.
have fun.
