Hi I am new here but have a couple of quesion about this swap before I start. I have an 07 NNBS Crew Cab 2WD. I know it has been done by a few members so I used their write ups as a starting point. What I am look at for my truck is to start with the ECM from an 09 with the same motor and a 6 speed. But from there I am not sure what will need to be done for the tuning and more importantly VIN.

Here is a basic list of the major components I am getting together:

1 ECM from an 09
2 Trans with TC
3 Engine Wireness from the 09
4 the shifter
5 THe cluster (to have PRNDM)
6 I have a VIN for the 09 already
7 Slip Yoke
8 Cooler Lines
9 Maybe a cross member ( or mod mine)
10 Dip tube

I am sure there will be some other little parts.

Now first to those that have done this, does this plan sound like it will work. Any thoughts or suggestions. And where you able to the TU/TD functions to work?

Thanks

the 09 ecm is pointless
the cluster may not swap over...you can just reflash yours current cluster i think a GM tech would know for sure
the easiest way to do it is to get a harness for an 07 denali 2wd and repin the few sensors
the tu/td is via BCM so your current bcm needs to be reflashed with a OS thats has the 6spd already and the same factory options as yours. the bcm is a touchy issue and i didnt deal with it.

I hear of 6 speed guys saying the TU/TD feature is kind of delayed, and you can easily miss gears if the buttons aren't firmly pressed.

I know my new f150 5.0/6speed work truck has the TU/TD and it has a laggy response. Although it is all stock lol.

the tcm cant shift fast enough using the tu/td feature. only reason for that feature is to select 3rd or 4th for towing or at the beginning of a roll race. my tcm tune does that for me so i dont have the desire to fool with the tu/td feature

My 4L60E swap to 6L80E didnt need a different flex plate .. Ls flexplates for nnbs are same as Confirmed by sponsors on here... I did howevr buy a new one from circle D just for peace of mind since i Have 155,000 mileson it

Ahh ok. I wasn't for sure on the 6 speed. I know when we did a 4l80 swap we needed a different flex plate

I never asked about the 4l60e swap to 80E ... Only the 6L80E i was swapping... Go to circle D and Ask Chris .. He will know and point u in theright direction .. My understanding was its the same on all nnbs Ls flexplates and only needs spacers for certain circumstances .. But im noexpert .. Chris or other sponsors will know for sure

the 4L80e is a 6 bolt compared to other trans thats why you run that flexplate unless your converter is built for a LS1 bolt pattern basically
