ATF fluid type/ best price ?

They would run just fine on used filtered french fryer oil guys.

Yea they always said use one only in that, and the other only in this, but lube places and trans shops use bulk Dexron in EVERYTHING.

Type F does shift a little better (Firmer) because it allows a little less slippage on clutch and band application.

Oh yea, Wally World here too.
