front and rears use the same,

the gearbox has its own specific MT75 oil

the transfer (inc the centre diff) uses Dexron 3 oil,

**BUT**

using the dexron 3 and mt oil in the box and transfer does make it nopisey when its hot and it ralltes like a bag of bolts,

some tuners have found a mobil oilt hat they use (the same in both) that stops this, and keeps the gears changing nice,

IIRC, Stu has some used it as has Gaz@CPP in cheshire (when he was cossie powered before he wnt all evo on me )
