Dextron II replacement

Hi all,

This may have been asked in the past but I can't seem to get the hang of searching for specific posts with the C3 search engine. 78 automatic trans calls for Dextron II. No longer available in local stores where I have looked. I'm sure I could get it online if necessary. What can be substituted for Dex II or is best to stick with Dex II ? The personnel there were not sure so I figured I'd better ask the people who know. Thanks for help with this, past and future questions I will have.

As with MOST fluids you can always upgrade to a newer type of fluid.  Dextron 4 or 5 will be fine.  NEVER go to an older rating.  If it calls for 4 do not go back to 2.  Brake fluid does not follow this rule.
