I've done a drain and plug with engine and auto box (I know not the best but I have to shoot up north so no time) and factory manual says 8.5ltrs for the box and 4.3ltrs for the engine. The auto box if it has torque converter and being still a bit new to Magnas, does this model have the torque converter and is that amount of oil right?

Engine takes about 4.3L, so a 5L bottle is plenty. Use the dipstick to get it right.

Autobox - a dry refill might be 8.5L, but a quick drain will not remove all of that, so you really need to top it up using the dipstick for the auto box. You will need the right trans fluid. How much you need depends on how much came out. lol

Yers, the Magna autobox has a torque converter.

Cheers MadMax, that's all I needed to know. It'll do till I get back from QLD.
