Very straightforward. Jack her up. Jackstands of course.
Slide under there with a big screwdriver, a light , and a collection pan.
Use the casting surrounding the torque converter as a fulcrum to
lever the screw driver blade against the TConverter . Rotate it around, in the direction the engine normal runs, until the drain plug appears. It's an
allen can't remember so bring a few under the car with you.

Next drain the pan with the drain plug. Finally remove the pan bolts and
drop the pan. Are we soaked yet?

Filter is three phillips screws. Pan bolts are very low torque. I use an inch pound torque wrench, but you could get by with just a 1/4 inch ratchet and light torque.

A word of caution, there are good tranny kits and not so good. I can't remember the name of the good ones, but that is what you want.

There's a lot of info in the archives if you use the search feature.

Enjoy,

Steve
