So just updating this thread. The Aisin fluid quieted down the transmission a bit after changing the fluid. It was blue. Old fluid was really dark, reminded me of dirty motor oil. Anyhow, it was easier than an oil change. A 19mm socket on the pan on drivers side and a measuring bucket underneath so I know how much came out to put in. It was a drain and fill. Took about 5 quarts.
Bucket I used was similar to the one below, except it was 4 quarts. When it got to the 4 quart line, I simply put my thumb over the hole and my father poured out the old fluid into a larger container and I placed the empty bucket underneath again.
