I would like to know when changing the transmission fluid on the 2003 Honda Element requires to drain it twice. Is it OK to drain the old transmission fluid and replace it with the new one without having to do the same procedure twice?
I only did a brief search on this. Did not see a requirement to do it twice immediately. However, I can see doing it again after driving it awhile. A drain and fill replaces slightly less than one half of the fluid. Repeating the procedure after driving would further refresh the fluid.
You might also change the transmission fluid filter.
