JDTRIP,


Everything I read was that those motors were not into production until November 1st.


You just blew our "intel" right out of the water. Sure would like to see a picture of what you have under the hood.

What in your manual says you have the LLY motor. My manual is filled with LLY information, but I still have the LB7.

Plus if you did get an LLY motor this early, you'd better keep it locked up and garaged otherwise a few characters might come over and borrow a few of those improved engine parts

I wish i would have known about this site before i bought my 2004 a few weeks ago. I would have waited. It is just like when I bought my 98 and read an article a week later that they were coming out with the silverados in 99.

I wouldn't worry about it, there's tons of hype and not much substance at this point. Enjoy your '04, there's certainly nothing wrong with it.

somekevinguy,


Like Cam said enjoy it!


I've been holding off on ordering a new 2500HD for the last 2 months. I'm just going to place an order with my dealer and see what Duramax I can order next week. If only the LB7, thats what I'm going to get then. All the hype is realy unknown and GM is not saying enough in response to my e-mails.

The interim 2004 Duramax 6600 diesel engine (RPO LLY) becomes available January 2004. Though similar to the current production Duramax 6600, this engine offers some significant differences. The GM Service Technical College (STC) will offer an updated Diesel Engine Performance course to reflect the changes. Refreshed and updated CBT, IDL, and Hands-on course components will be released successively beginning April 2004.

To enable technicians to promptly offer service to customers with the new LLY Duramax 6600 engine, GM STC will release a supplemental video course in December of 2003 that focuses on this new engine configuration. Technicians with credit in any of the current Diesel Engine Performance 2001 course components may take this video course to receive a cross-credit to the updated course components.

Technicians are encouraged to participate in opportunities to complete the training components within the Diesel Engine Performance curriculum path. This curriculum path provides the foundation for December’s supplemental video. This strategy will not only increase the dealership’s overall Service Training Standard score, but will help ensure that the technicians are prepared for LLY Duramax 6600 customer concerns and able to fix them right the first time. Dealers that complete the current standards before December will be in an excellent position to address the needs of the LLY Duramax 6600 customers. Additional communication about the new courses will be available a few weeks before their release.

- Thanks to Steve Sternicki

Sorry for causing a stir about having the LLY motor. this is my first diesel and I thought some things in the diesel supplement pertained to this truck, but I was wrong. any way I did take the truck to florida and back and it is just great. fuel averaged 19.8 down and 19.5 on the way back. speed never exceeded 65mph. going it never was over 55. these are great trucks, and I'm very happy with the LB7 motor.
