Hi, newbie here... My 1973 D-200 PU is no longer showing up in online search results and I need to get some ATF. I put my manual somewhere for safe-keeping. Can I use Oreilly Premium ATF ? bottle says "for use where Dexron-3 or Mercon fluid is specified. thanks.

 

F-Type was used in the older trans.....
If the trans has been overhauled with all the updated clutches then the Dexron or ATF+4 can be used...

 

Just plain old type F is all you need….

 

Yep, just this stuff here. Long as it says Type F, you are good to go!
