75w-80 is hard to find in the aftermarket.
Most GL4s that are not marketed as ATFs are 75w-85 or 90.

Maybe the 420g is sensitive to viscosity and might be why the OE fluid works so well.

I used D4ATF, MT90 and those caused my gearbox to not shift well. Maybe it needs 80 weight to allow the synchros to speed up?
