Hello Everybody,
with all the discussion about automatic transmissions (and with us
about to do a fluid and filter change) i decided to do some research
about how to do a fluid and filter change. i found that you actually
only change about 1/2 the fluid....well, i want to change more fluid
than that and so this is what i have found:
From my 1986 Owner's Manual:
Fluid capacity for 22R & 22RE engines
Dry fill = 6.9 quarts
Drain & refill = up to 2.5 quarts
From a website that talks about car repairs:
---------------------------------------------------------------------
The best thing to do is to change out ALL of the fluid, and this is
something a person can do themselves.
First, drain the fluid from the pan. Once you've replaced the
filter, the pan gasket, and reinstalled the pan, you're ready for the
next step.
Fill the transmission to the proper level using the proper type of
transmission fluid. Then disconnect the return transmission line (the
line in which transmission fluid flows from the transmission cooler
back to the transmission). Once the line has been disconnected,
attach a clear piece of tubing to the transmission cooler, the same
diameter as the transmission line, approximately 5-6 feet long, using
the transmission line clamp to secure it.
Place the unattached end of the clear tube in a plastic, one gallon
milk container and place it where it can be seen (like not under the
car).
For the next portion of the procedure, make sure that the parking
brake is set prior to continuing. Start the engine. The transmission
may have to be put into "Neutral" or "Drive" in order to pump the
fluid from the transmission. I usually put mine in "Neutral" to
accomplish this step. While the transmission is pumping out fluid,
you can monitor approximately how much fluid has been pumped out by
looking at how much fluid has been pumped into the plastic milk jug.
While fluid is being pumped out, slowly add new fluid to the
transmission at about the same rate as its being pumped out. This
keeps the fluid level at, or near the proper level. You can see the
condition of the fluid through the clear tubing as its being pumped
out.
After approximately 4 to 5 quarts (obviously, if it's more than 4
quarts, you'll have to turn of the engine, and fetch another milk
jug) of fluid have been pumped out, you should notice a change in the
color of the fluid. It should go from a brownish red color, to a
bright pinkish red color. When this happens, all of the old fluid has
been replaced with new fluid.
Be careful not to overfill the tranny during this procedure.
When completed, reconnect the transmission return line to the
transmission cooler. Check the fluid level as you normally would, and
add fluid as required.
This fluid change method is twice as good for your transmission as
the method of only changing out half of the fluid is. Happy shifting!

this information is for a Chrysler automatic transmission but i
wonder if it could be applied to our Toyota's??
What do you all think......??
