2018 TRD Sport extensive transmission drain and fill

Hey all new guy here. Question, if I want to switch out “all’” transmission fluid on my Taco. Can I just do 3-4 drain and fills? Make sure I measure exactly what I took out with each drain and replace that amount with each “fill”? I know there is another procedure, but this is what I’m accustomed to. Anyone else done this same method I speak of on their 3rd gen Taco?

 

Effectively sure, you can simply do a ATF oil change every oil change and achieve the same results.

Inline flushes with an exchanger is ideal as its hard to drain all the fluid.

Also you can consider removing the pan and cleaning it out.

 

Some here observe and complain that the AT's are often low on fluid from the factory. An ounce for ounce exchange while not bad, may leave you with the same underfilled trans.
