Well I just picked my Sienna up from service at Toyota and the Tranny fluid was perfect!
Brakes, oil color,
tires, e'thing is fine so she is no worse for the wear towing 6000 miles in 100+ temps up and down hills. The temp gauge never moved and they said 3000 RPM's wont hurt a thing and to use 5th gear only when at cruising speed on flat ground so the tranny isn't constantly shifting which I was already doing. Now I feel better.
Thanks for all the info! I love this site!! Need to make a donation as soon as I figure out how since I have learned so much and did find Tabitha here.
