Unfortunately, the TCM and ECM and BCM all communicate with each other. Basically, if the TCM fails to properly report whats happenning to the ECM, you will find that the engine will go into a "limp mode". Same can be said for if the TCM is still there, but it detects an issue (like transmission isn't reponding since it isn't there). However, if money is no object, then you can probably get around this whole thing by installing an aftermarket engine control management system to run the engine instead of the stock ECM.

As for the 350z trans fitting on the Titan, sorry, I don't have an answer for that. Maybe the first question would be will the flywheel even bolt onto the Titan? The 350z flywheel is a dual mass flywheel and it is indexed to the crankshaft, meaning it only goes on one way and only one way onto the end of the crankshaft. How this will work on the Titan I do not know. Unless you just swap out the Titan V8 engine and put in the 350Z engine. You can supercharge or turbocharge it to make up for some of the power difference. Hehe, just throwing out ideas.
