Thanks, I didn't know this. How bad is it that tranny and AWD oils have not been changed in 7 years/75,000 miles? Is it possible that MM has not displayed service code for them yet?MM is a tame animal - it can be reset by pressing a button. And it does not matter what MM says. You can change the tranny fluid yourself as long as you have a 17mm socket, 12" extension, and a 3" breaker bar. You do not even need to jack the car up. Same about AWD oil but this time you need 4-5' or a 1/2" plastic hose. Timing belt is a different story.
