Ok, I'm freaking out! I have 27,500 miles and my service manual does not call for a trans service of ANY KIND until 30,000. No filter, no external filter, no frame mounted filter, no fluid change, no flush, no nothing and I'm using the severe service interval. I even checked on line based on my profile, driving habits, etc. and the recommended service based on my profile does not call for any type of trans service until 30,000 miles. I'm driving an 06 f-350 cc 4wd 6.0 psd. What did I miss on the service interval?
