Wanted to introduce myself and say thanks to all the people that have shared their experiences. I have learned a great deal. I purchased an 03 CC D/A in Jan 03. I immediately searched for web sites to learn from. I've never considered myself a joiner so I procrastinated on actively joining any of them. When I was ready, another site crashed so I hesitated even more. I now believe that I have enough experience with my D/A to share and am thrilled to find this site.
At 3300 miles I added dual Racor 660 fuel filters (30u & 2u) pre-oem. Both w/heaters (still unwired). At 4100 miles I added an Amsoil BK17 Bypass kit, changed my Allison filter, and changed my grape juice. At 4700 miles dealer changed my diff and front xfer case fluids. Currently have about 5100 miles on truck.
My only repair has been to my A/C. It was very poor (very hot in Kansas). Took it to dealer and informed him of TSB's I learned of. He called back and told me that they didn't apply to my truck. He did order a part. When I questioned him he told me that they had replaced an orifice tube on another truck w/some success and that GM was issueing a TSB for that. Once the tube was replaced the A/C was great. I questioned the service writer if they had seen any recurring problems on Duramax's and he said no. They hadn't changed out any injectors for a long time (> 2 years). A/C seemed to be their biggest problem.
My personal toys include a 1991 Miata w/26K miles, a 2000 Searay 270 Sundancer sport cruiser (wish I could use it more), and a John Deere 790 w/loader.
Thanks to all.
