Hello

I need to use a MS-9224 oil in my CRD manual gearbox (NSG370).

I can't find it but I've been told that it was superseded by the ATF+4 used in the automatic gearbox.

any help please

royal purple synchromax lists it is compatible in literature. I had a ford contour with the mtx-75. it used atf in it. I had no problems using chrysler atf+4 in it (for cheaper synthetic oil). shifted fine even at freezing winter temps. Ford later spec was their "Ford honey" as owners called it. Full synthetic oil light golden color and almost 19.00 per bottle.

one link on oil compatibility.

Now have GDE full torque eco tune and eco transmission tune. Used an 02 liberty trans computer for my new trans tune.

I used Penszoil Synchromesh fluid. (same NSG370 trans with 3.7L gasser)

It had the required rating in the small print on the bottle.
