MG ZT 260 gearbox and diff oils?

[David]

Hi - can you tell me the correct gearbox and diff oils to use for the V8, and also the quantities?

You would be well advised to sign up as a full member, David, when important data like that would be readily available, plus a LOT of related information, 'How to' threads and advice, which could prove indispensable .... but for the time being, here is the data you ask for at the moment:

Rear Differential
There are only three oils available in the UK that have full sign-off for the unit. These are:-
Mobil SHC80W140 id
Castrol SAF-XJ80W-140 as originally specified has been replaced with Castrol Syntrax 75W-140
Morris Lubricants Lodexol XFS 80W-140 (the "favourite" one according to the specialists).
Capacity 1.6l

Manual Gearbox
Dexron 111/Mercon V ATF (Ford strongly recommend Mercon V).
How to here - Gearbox Oil Change
Capacity 3.0 litres wet fill
Original information was Capacity 3.6 litres wet fill or 3.8 litres from dry, figures sourced from the Mechanics Training Notes and have since been amended by Tremec to 3.0 litres wet fill.
