When you pull the trans dip stick look for the stamping indicating the
type of fluid. The new ones are usually "W/S" (world standard).

Toyota says that it never needs to be changed, but Toyota is the only
manufacturer I've see with a drain plug on the pan.

Even using the best filters, all drive (hydraulic) fluids will
eventually break down chemically from the normal heating and cooling
cycles, and mechanical movement (cut) causing friction and more heat.
They tend to loose viscosity, anti-foam, and lubricating qualities, and
I'm sure a few more.

W/S fluid is rather expensive (about thirty five to forty bucks a
gallon), but fluid is usually a lot cheaper than transmissions.

That was what I was thinking, oil is oil and will still degrade
overtime. I just don't know what mileage should I change? Not to
early, not to late. So I check under the hood but not religiously.
This is only my 2nd car with A/T. On my RAV 4 I followed the owners
manual and changed 40k. But now If I follow my manual its never.

My Frontier has a drain plug on the pan. Some Fords do. I suppose if
you are going to change the filter (screen), then you are going to
have to remove the pan either way, so why include a plug? My Frontier
doesn't have a replaceable filter, so removing the pan is not
necessary. Fords used to include drain plugs on the torque converter.
That was a nice feature, since there is more fluid in the converter
than the pan. Lately they have dropped that feature and recommend the
use of a fluid exchange machine instead.

My Nissan doesn't have a replaceable filter. I tried to buy
one......the parts department said there is a screen in the
transmission, but you can only change it by disassembling the
transmission.....

I agree. The 6 Speed Automatic in my Ford Fusion is a member of the
same AW Transmission Family as the Camry 6 Speed. Ford calls for a
special fluid for this transmission (XT-8-QAW / WSS-M2C924-A). I
wonder if it is the same as the Toyota W/S Fluid?Do you know the P/N
of the W/S Fluid? According to one supplier Ford XT-8-QAW is
equivalent to 08886-81015 and 08886-00405. Mobil recommends Mobil ATF
3309 for my Fusion (see
http://www.mobil.com/USA-English/Lub...l_ATF_3309.asp )
.. Personally, for the RAV4 I am going to stick with fluid from the
Toyota Dealer.

I'm sorry C.E., but I don't know that p/n of the fluid. What does the
stamping read on the dipstick for fluid requirements? It usually says there.

Like you mentioned in sticking with the OEM fluid, is always good. Some
manufacturers of equivalent after market fluid strike a compromise for
multi use applications and may formulate to a slightly lower performance
level to accomplish that.
