Today I syphoned what I could from my S1 gearbox and I was a little bit surprised to find it was a rather thin red oil, presumably ATF?

I had bought some semi-synthetic 75w90 gearbox oil to refill with, but fearing this would be incompatible with the residual red oil in the gearbox, I filled up with some ATF-Q ( Dexron II type ) fluid.

I'm looking for confirmation that this will be ok, because the search brings up conflicting opinions.

It's a pity Ford never fitted the Type 9 ( N type ) box with a drain plug.

Also my Haynes Granada manual lists the gearbox capacity at 1.9 litres, but I only managed to get a litre in before it started overflowing.

Hi Alan,
I had about 2 litres left over from changing the fluid in the old Mondeo Auto box, so about a litre left in the container now.

Why do you recommend repeating my actions of today?
To be honest, the old stuff looked pretty bright & clear. I just wondered if it was a special Ford fluid"

Do you use ATF in your S?

Thanks for your input everyone.

The gearbox has always been good with a nice slick gearchange ( except when I fluff it on the odd occasion! ).
So ATF it is then. smile

I just wondered if there was a special Ford gear oil that was coloured red.
