Pics are messed up... About to do this myself, I think I'll go with the 70268 as well - temps range from -40 to over 100+F where I live...
I need coolant, right? Or just ATF?
If and when I buy coolant, this is the right stuff, it's the "red" genuine coolant, right? Amazon.com: Toyota Genuine Parts 00272-SLLC2 Long Life Coolant - 1 Gallon: Automotive
You don't need coolant, just ATF. I needed about 2 quarts to refill the system after it was all done.
