Correct trans fluid for 727?

[db]

It does say Dextron II amongst the small print but I'm not happy with the way the trans works. It's slow to get moving when it's cold and shifts 1-2 with a thump if I'm light on the throttle. Fluid level is correct.

I have just changed fluid in my 904 and I went for Comma AQM (mineral), as it was more confusing to find one.

Have not run it yet so don't know how it will be.
