What car are you talking about? I wanted to know which oil to use in a MT75

I'm sure MT75 box takes FMT. Its the transfer box that is ATF but it is over a year since I last changed mine so don't take it as gospel.

MT75 takes Dex III ATF.
Don't know about B&W T5

Do you know what goes in the rear axle as it has a limited slip diff and I don't want to kill that

MT75 Gear box only uses mt75 oil transmission oil sililar to auto transmission oil 1.2 ltrs ( ATF FOR 2WD Gearbox and 4x4 transfer box use only)
Diff use 75/90 semi or full synthetic 1 ltrs

Note diff MUST, use LSD oil, not just general oil.
A T5 box is normally used with ATF, ATF then attacks the pads on the selector forks ends as these are made from compressed paper/card, GEAR OIL doesn't do this and is why I use it, a 70 weight.

I thought the LSD in the sierra was a sealed unit, therefore you dont need a specail lsd oil?? The gear oil in the diff wont come into contact with the LSD unit itself.

I also thought that ford put ATF in the T% box from the factory? So you use a 70 weight gear oil in you T5 box tabetha?
