kiehaefer trim tabs fliud
 

i was looking thru some post as to what fluid for my kie trim tabs...thought it would be atf..........

BUT,,,,some people posted it was 10-40 motor oil!!!!!!!!!!!!!!!!!!!!!!

WRONG..

as stated on the instruction i have from 1989,,,states clearly use dextron atf only

.end of story.

ATF, SAE 30, motor oil, It all works the same. I would imagine that the atf works better because it has a lower viscosity. If it has dexron in it now, stick with it, but in the end any kind of motor oil or hydraulic type fluid will work.
