No it is not. It has a different friction coefficient to aid smoother gear
changes and it has far better shear stability. This type of oil is now
fairly universal as factory fill. Even Land Rover have changed over and now
refill older boxes with it at service time.
This type of oil was pioneered by Ford when they had reliability problems
with their MT75 gearboxes [or was it MT94?]. Changing to a special oil
formulation ensured increased reliability and was the precursor to many
others following the same route. It made a huge difference.

A few of the available MT oils are honey coloured although some are red and
appear identical to ATF in appearance. They are fully miscible with ATF but
should NOT be used in automatic transmissions.
