====================================
The engine oil I use has "ounce" markings on a translucent strip on the
side, so I pour the drained transmission fluid into the empty oil
bottles filling them to an even number of ounces, then use a measuring
cup to add back the same amount when re filling the automatic
transmission.
When checking the final level, the fluid needs to be "hot." That is,
normal operating temperature, typically driven at least ten miles
before the final check, but not idled in city traffic on a hot day with
the air conditioning on, or driven at continuous high speed, just fully
warmed up to normal operating temperature.
Because the fluid expands when heated, if you fill it when not fully
heated, it will be over filled at operating temperatures.
Sometimes, the drain plug is hot to remove by hand. If you get a small
telescoping magnet, and let the fluid drain over night (more drains out
that way) you can retrieve the drain plug with the magnet easily when
the fluid has cooled.
You'll most likely need a 10mm Allen head socket, and it's helpful to
have a 3/8 to 1/2" converter bit so you can easily apply the extra
torque with a larger wrench when removing the drain bolt.
It is best to use a new aluminum gasket when reinstalling.
