Long life with carefree performance
is something
every transmission-repair
facility expects to have with transmission
fluid. And at one time it
was easy and carefree; now we are
seeing more and more manufacturers
requiring specific fluids for
their transmissions. Why?
In my opinion, this is half marketing,
half technology. Let me explain:
When automatic
transmissions started to become
common and popular in the late
1940s, many of the deficiencies of
earlier fluids (straight mineral oils,
mainly engine oil) showed that fluids
used in automatic transmissions
had to perform many
demanding tasks that were beyond
the capabilities of the available oils
of the time.
