[speeder]

The only thing I can add is that I had an old 2001 Honda Odyssey and when I wanted to change the transmission oil, everyone on the forums swore by Maxlife including the independent shops. Everyone had a story about running their vehicles up to a zillion miles with it, etc. I used it instead of the dealer stuff.

For the old Toyota, I’d check with the dealer and see if they have superceded the spec on the fluid. Good chance over 20+ years. Good luck.
