i think, and don't quote me on it, but the 01-02 had weaker torque conveters if u added a big chip. but i'm a cummins guy so what do i know! as far as i know they are reliable, good towing rigs. they also ride nice and smooth, if u like that sort of thing. the allison takes a while to get used to. i know some of the dmax guys will be able to help u better. good luck. oh and i loved my old 6.5. damn divorces anyway.

As Nasty pointed out there isn't much diff between an 01 and 03. The LB7 model ran from 01 to 04.5.

The only common problem with the LB7 are injectors. They fail often. The 200k extended injector warranty also has a 7yr stipulation. For an 01 your not going to have much time left under that extended injector warranty if it hasn't already busted 200k. Even if you got an 03, the warranty is not a for sure thing. If you read the fine print it only covers a very specific type of injector failure and depending upon how closely a dealer follows the rules you may or may not get coverage. Injector replacements are very pricey!

Mine failed, wasn't covered and burned a hole in my piston. So if you ask me, and your dead set on getting a GM truck I would say get an LBZ. Some of the LLY's have overheating problems but there is a cure for that. There are some on their 2nd and 3rd set of injectors with the LB7's, some are getting replacements under the extended warranty and others are paying out of pocket.

Good luck!

Yep - Injectors. I'm on my third set, but both times they were replaced under warranty. Got a little over 80k out of each set.
