I have 11K on my 2500HD D/A and I am curious what are some of the maintenance schedules that everybody performs. I lost my diesel supplement guide so I have no idea what it says. Give me some ideas on what everybody else does for maintenance...besides change the oil. Like Allison fluid change, fuel filter, air filter, and injectors. Open for all suggesstions.

Go to the DIY topic on this site and there is a listing there.
