5.4 engine swap

since the 32 valve navigator comes with a 4r100 transmission the ecm won't work on a 4r70 trans...
and if you swapped over the 4r100 trans also, you'd need a new drive shaft, and a custom tune to allow the ECM to communicate with the new trucks cluster
so either way you're gonna end up with a custom tune, total cost of the swap is up to you

terajerame, So after the swap, the engine will start and run but will need a tune eventually..is that what you are saying...I have cruised through a lot of the these threads and I have found nothing on that. I am doing my swap next week, Already bought all my parts from a 00 Navi. I think I am good

So, I need help, I am in the process of doing the swap. I need help with the radiator hose setup. Do guys just use the Navigator setup or do they use the rad. outlet off the 2V(block part)? I am missing something on the sidee of the upper plenum that has 4 small bolts? Don't know what that is. Do guys use a Navi radiator and hoses or what? Because I need to get that stuff if they do.
