The fluid appeared to be in excellent shape, a murky purple.

FYI, my dad ran his 1990 LS 400 to 330,000 miles without changing the transmission fluid and never had any problems or noticed any issues. He has done two drains/refills since then per my suggestion, but I don't think he's noticed any effects.

~2 qts is correct.... see here:

Dry fill 8.9 liters (9.4 US qts, 7.8 Imp. qts)
Drain and refill 1.8 liters (1.9 US qts, 1.6 Imp. qts)

thanks so much, this is what i was looking for all over the site and couldn't find it easily.
