Not a lot to it, really.
You'll need to remove the plastic sound-muffling
enclosure(s) underneath the engine/transmission.
The transmission pan has a drain plug - Use it to
let the first few quarts out of the pan. Then
remove the pan. The filter is inside - it removes
with phillips screws - three of them, as I recall.
Be prepared for a shower of ATF as you remove
There are a couple of drain plugs located around the
periphery of the torque converter. You must rotate
the engine, either manually, with the key, or using
a remote starter, to position one of the drain plugs
above the access opening. This can be a bit tedious.
The drain plug is an allen head plug - 5mm I think?
Be sure to use a new pan gasket when buttoning it all
Just fill from the top, where the trans dipstick resides.
The torque converter will take care of itself. Be certain
not to overfill. I believe capacity is just above 6
quarts. I've read to add four, run the engine for a few
minutes, and then begin slowly topping up.
