Oh, you all jest.
Man, I hope you're jesting!
Transmissions are real expensive when they've been ruined with
the wrong fluid!
Ford Aerostar transmissions are famous for self-destructing under
load or hard driving. I've noticed that Ford has addressed this
issue with continual advances in fluids -- in fact, Ford has
seemed to lead the field with the introduction of stringent
standards for transmission fluids.
I took my Aerostar in for a real transmission oil change -- not
the usual sissified way: dropping the cover, dumping out the
fluid, and changing the filter. This leaves all the old fluid in
the torque converter (from which car makers no longer provide us
with a 50-cent drain plug -- clever corporate bastards). I had
the entire system pumped out with an expensive machine, and all
the fluid replaced with Castrol ATF. This service has become more
common recently. If you're really crafty, you can do it without a
special machine by using the car's torque converter itself to
pump the old fluid out and the new fluid in.
The difference in the car's performance was amazing. Shifts were
smoother and more timely. There was a very marked improvement in
power (which translates into an improvement in gas mileage). I
attribute this not only to the fluid change, but also to the
superior quality and reduced friction of the fluid.
When it comes to recent Hyundais, a specific fluid is
indicated -- a fluid that's not yet commonly-found. I don't think
that it's ever wise to substitute an older standard fluid in a
case such as this. If it were OK, the manufacturer would
certainly have gone with the cheaper fill at the factory! What
we're dealing with here is a contraption made with greater
precision than heretofore. It requires the appropriate liquid for
Transmission fluid provides a precise match in characteristics of
both lubrication as well as a desired amount of friction. The
good news is that Hyundai isn't alone in using the special stuff,
so it is only a matter of time before we find the specified fluid
on the shelves of our friendly neighborhood auto parts stores,
and at a more reasonable price, too. That's where Ford's latest
fluid can now be found, and it's become standard for other cars,
too. And that's where we're going to find our Hyundai-spec fluid,
too. Just wait a little longer.
