Thanks - that is an interesting approach. I cleaned a lot of sediment out of the pan, which would be missed if it was just a fluid change. I can't imagine pumping that $15/qt fluid through as if it was a brake fluid flush. I wondered if the front pump on the trans would pump out the fluid even if it was sucking air, until the torque converter was empty.

I'm kind of surprised that a pro tech hasn't chimed in since this is probably becoming one of the more popular DIY jobs as these cars age.
