I have now owned my 1992 Eunos automatic for four years. It has been well maintained before and during my ownership. My concern is regarding the transmission fluid.
I have no record of it being changed. It looks in good condition, still the correct reddish colour and does not smell burnt. Should I change it? if so does anybody know the
procedure? The car is showing 89,500km which I cannot verify as genuine, but the car is in superb condition, the underneath is as good as the top, so it could be true.
I’m always of the belief that any fluid, oil, antifreeze, brake fluid, should be changed at specified intervals, but the auto gearbox oil, I cannot find any information for.
Can anybody help me?

Hi Roger
miata.net have some good info on the 1.6 auto, including atf change procedure, or google miata 1.6 auto atf change
My 1992 1.6 auto, ATF looked clean & not burnt like yours, 160,000km, last change unknown, my mechanic advised changing atf, saying oil does not last forever
I got OE filter & sump gasket from mx5 parts
The sump has to be dropped as no drain plug
Filter awkward as 1 of the screws has a none captive bolt
original filter was clean on my car
This has made a much smoother gear change, no ill effects after 12 months, new oil still clean
I think the ATF should be changed every 60,000 miles
Some people have done part atf change, using vacuum pump down dipstick, but this does not allow filter change
Regards

Also check the condition of the ATF oil-cooler, they can corrode and suddenly leave you with no drive when all the oil drops out.
But see this thread for more experiences from others.

ATF oil cooler is in bottom of radiator on the 1992, worth checking as Richard says
The ATF cooler is not visible as it inside the coolant rad but you can check the pipes going/coming from it.They rarely give trouble and piping to and from gearbox itself.
