Regarding Neil (just call him Darth) Vedder's challenge to
G. Riehl, here is his reply. All y'all do what you want with your
transmissions in regards to fluid. I know a torqueflite shifts more firmly
than other brands and I LIKE THAT because it means longer life. For
your hobby cars doing a few hundred miles a year, just be sure your trans has
FLUID - of any type - you are correct it won't make a heckuva lot of
difference. But for those who drive a collector car a few thousand miles a
year or have been known to leave a stoplight shall we say "RAPIDLY", putting off
the expense of the rebuilding is far more important than making it shift like a
Generally (inept) Motors car.

Well, Wayne, all I can say is that Mr. Vedder has
had very good luck. Some trannys I have taken apart that have used other lubes,
especially D/M, the friction linings get "little" bubbles between the material
and the steel disc they should be attached to. This is a result of whatever
additive(s) that is in the fluid. It acts as a solvent. If Chrysler engineers
have suggested type F, they sure have a reason for it. Trans fluids were
discussed between me and the engineers at Colonel Drake Refining in Clevelabd
years ago when I ran a fleet of over 250 vehicles and had the fluids tested upon
drain.
They suggested different types that suite
the operation of various engines and transmissions. Some got one type, others
got another, different from factory specs. They lasted beyond normal life which
was a great finantial savings and for down rime.
I was trained by a man that had retired
from AAMCO Transmissions after 35 years, training service personell that
went to work in the various shops. To date, I have been rebuilding trannys for
28 years.
In Mr. Vedders case, if it works for him,
fine. Given a time period that his tranny will fail is not what I can predict.
It all depends on how it is used and maintained. I have never had a "call
back" that was my fault in rebuilding or suggesting the type of fluid to use in
more than 700 I have done. Just lucky, I guess.
Oh, one more thing, on Chrysler's 4 speed
trannys (1964 thru 1969), they used to state "use Automatic Transmission Fluid"
to "top off" or "refill". That has been changed also in late1966. Now they say
to use 80w gear lube. Those engineers must know something. Gettrag trannys
(Dodge trucks) were failing, then the engineers said to ADD 1 to 1 /12 more
quarts. Bearings were going bad. Not enough lube. Bad enough that that one would
have to buy a new case for over $1,400, plus needed parts.
