Is the automatic trans fresh rebuild or old? Either Dexron or Ford F fluid will work fine

Use gear oil in the differential. 80-90 weight is fine

thanks crosley... i believe was a rebuild within 5 years or so. i was looking in the original manual for recommended fluids , but wasnt sure if there was something better and more modern now that guys are using.

The the 85 - 140 is good will work fine. Ford specs recommended type F gives firmer shifts that trans was designed for slippage equals more heat. Dextron has more slip built into it even the gm racers use to use the type F to get firmer shift. Your choice but I would only use the F in the old Fords into 1970's.
