Stop in for a cup of coffee

I agree. The racers started using type F years ago for firmer shifts. Most street cars don't need firmer shifts and if you shift kit your Tflite it will have them with Dexron. My Swinger shifts firm with a little Kickdown adjustment and Dexron.
Yes but the push buttons need that thicker type F with their dual pumps and higher pressure requirements, at least with factory valve bodies
