I've got an 07 Corolla with 36k miles, ATF is factory as far as I know. I want to avoid having to drop the pan, so I would like to do a cooler line flush with the Redline. That would be followed with a drain and refill every 15-20k miles. Is that overkill? Should i just do a drain and refill with the Redline now and every 15-20k in the future?
Also, I wanted to get a Magnefine filter. How often should they be changed? Lastly, do any Corolla owners know if i need a washer for the ATF drain plug?
