Hello

How much oil does the gearbox take, and what type?

 

2.6L (listed), changed mine last week and took just over 2L, oil to use is ATF.

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.

 

Sorry 2wd Saff/3dr

 

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?
