Today I bought the 2006 Chevrolet Silverado 2500HD Truck Extended Cab with the 6.6L Duramax 6.6L V8 Turbo Diesel and Allison Automatic 6 Speed Transmission I had been looking at. It has only 72000 miles on it. I hope I will be as happy as you all have been telling you have been with yours. This being my first Diesel what maintenance should I be looking at?
Oil change and lube every 6-8k miles unless youre monitoring oil life through sampling or have bypass filtration (unlikely).
Fuel filter every oil change, air filter as needed, trans filter every other oil change minimum.
My 02 had 10-11 grease zerks on the front end. Pretty sure the 06 does as well. Not typical these days as most components are sealed in the front end on the other brands.
I'd pump out the OE trans oil in favor of a fresh fill of Castrol Transynd too. Ask any Allison repair shop about it and you'll find out why.
