I have an 02 6.0L that I want to build and put in my 04 sierra. Other than the cam bearing journals be smaller in the 02 block, is there anything else that is different between the 04 and 02? I plan on using as much electronics from my 04 on the 02 because of the truck being an 04. I just want to make sure everything will switch over to the 02 block if needed. My proposed build: 02 6.0 706 heads tbss intake truck norris cam ( still debating due to the possibility of having to get a new Torque Converter) HP Tuner 8.1 injectors

Yes there is one under the seat, I assumed that and the bcm communicated together. Since my truck wasn't factory heated seat/memory that it wouldn't work without reprogramming the bcm or swapping it out.

My understanding was my bcm wouldn't recognize the module under the seat so the heated seats wouldn't work, I could care less about the memory.. you could be totally right, I don't know.

I have an 04 GMC Sierra 2500HD and I am looking to add power and heated seats. My truck now has power drivers and non power passengers. if I pull a BCM, seats, and wiring from an 04 avalanche and do the turn key relearn thing, will everything work or do I need to take it to someone that has a tech 2 or the dealer? Thank You!

I just replaced my rear main seal and obviously you have to remove the transmission. After I got everything back together, I drove it around and noticed it shifts hard now. When I put it into gear it spits and sputters and eventually will die and it idles perfect. Never had any problems before shifted great and ran great. it seams shifting into 4th gear is smooth and normal but not the other gears. What could it be? Something electrical? 04 GMC 2500HD 6.0L 4L80E
