A big thank you to all of you who have participated and helped make this a great thread. Thank you especially to OP for his research and hard work.
I did this job this past weekend, and I can't tell you how nasty and grimy the "lifetime" fluid was. I got so dirty changing the fluid that I didn't have time to take pics. My cas has 162K miles. I noticed smoother shifting after the fluid change.
I used Valvoline MaxLife.
Once again, thank you all.
