what oils do I need for the sierra diff and MT75?
Unless they're special, I think you'll be OK with EP80/90 GL4 for the gearbox and EP80/90 GL5 for the diff.

If I recall correctly the gearbox needs a special oil, in fact I have some in the garage, will go and have a look exactly what it is called. HTH

Well that 's simple, it's called MT75. Stuff I have is Comma and states Ford Standard ESD-M2C186-A and is for the MT75 and MTX75. Cheers
