Hmm.
For those of you who may be uninformed, type F has more grabbers than
Dextron I,II, II and or IV.
As in days past and present, if you wanted crisp shifts from your power
glide, turbo 350, 400 0700 R-4  transmission the ultimate solution was
to use either blue B&M trick shift at 5 dollars a quart or red Ford type
F, at $1.75
It lowered trans operating temperatures simply not allowing the clutch
plates to slip.
They hook up much faster and don't build as much heat.
I use both B&M trick shift, and type F in my Vans.
No slip, crisp shifts, cooler trans operating temps, and longer trans
longevity.
I just had my 90 GL serviced at VW, having the trans fluid and filter
changed.
The service tech agreed with me, and used the B&M product I supplied
without a question.
B&M has been a longtime expert on automatic transmission performance
products and the best shifting transmissions forever.
Ford Type F has is the same product only in a different bottle.
Get out of the owner's manual and learn a proven old time solution for
much better automatic performance.
