Having worked on both Ford and GM powertrain projects for a Tier One equipment supplier, +1000
A year or so after I retired my old boss begged me to come back to help with GM projects. Offered me silly money, and I said NO.
And I'm seriously wondering what Recluse is smoking.
Type F is only for much older Ford xmsns. At least 10-15 years ago they got together and agreed on a common spec for ATF.
