power trim fluid

[IRish Wake]

The reservoir of the outdrive trim motor devloped a crack.We replaced the reservoir and now need to replace the hydraulic fluid.Volvo says ATFII(Dexron II).I checked with auto and Marine center and all I see is Dextron-III,some with Mercon.What is the right fluid? I have Hynautic steering fluid.Thanks The engine is a 41P-A W/290.

You may want to research the brand name you like and see if it is for one or multiple applications. This is an example for Penzoil

Hijole,penzoil Multi-VehicleATF advised to use in application calling for DextronII and III.Could be its the way to go.
