Considering the Hemi plugs need changing at 30,000 miles too it would be an easy to remember service interval. It's cheap insurance just like engine oil changes for those who keep vehicles a long time.
What does the owners manual say about tranny fluid changes? Also, im not the biggest fan of using those flush machines. From what I have read (I know its not personal experience, but seemed to be from reputable sources), that those flush machines have been known to cause issues mainly in higher mileage cars. I guess what happens is it forces fluids to move through ports in the direction it wasnt designed to and causes foreign debris to possibly damage parts of the tranny as it enters areas that it normally woudlnt. I dunno, like I said this is just what I have read. They simply stated the safest way to do tranny fluid changes is by draining and refilling...usually has to be done multiple times to get all the fluid. Can anyone else comment on this?
