Funny enough I was gonna talk up my 06 because of the lh6, lucked into that when I bought it because I had no idea. Good to know where my filter is though because that might be a issue I have.I prefer the 02-04 in V8 models. None of that AFM/DOD crap, and in line fuel filters, vs in tank fuel filters. But I am also not against the 05-09 models with a V8, I just know I have to get the PCM reprogrammed. Which for all intensive purposes, should be done no matter the year or engine.
From my time searching on here, I was under the impression that the earlier 360's had issues with the TCCM? Other than the fan clutch and ecm there hasn't been any updates to the 4.2 engine mechanically?Just slightly better mileage with the I6 but having the V8 is nice. The early ones with the V8 are rare. 05+ are a bit easier to find but are not nearly as plentiful as the I6.
I would suggest 08-09 as they would be younger, hopefully less mileage and they had replaced the failure prone electro-viscous fan clutch with a thermal clutch. Also, the PCM is a bit more tunable for speedo accuracy if the tire size or gearing are changed. Look for either 3.73 or 4.10 gears as the 3.42 are dogs and would help for towing if that's a consideration. They usually came with 3.42 unless a different one was ordered or the towing package was included. Both are rare.
Other than those things, all years are pretty much the same.
I have heard that but not experienced it. I understand they can be simply swapped out with a newer used one. And around here TCCMs can be had at the Upullandpay for under $20 and if you know how you can pull one out without a single tool.earlier 360's had issues with the TCCM
