If you replace the 3.5L GDI engine in your 2004 Axiom you will need to wire in the Engine Control Module (ECM) for the replacement engine. Replacing the engine will create a new problem in that the AW30-40LS Transmission Control Module (TCM) will not be able to communicate with the replacement engine ECM so the transmission won't operate. This means you will have to replace the complete powertrain and all the wiring that connects everything together.

It's only that mine is a 3.5l and the 02 model has a 3.2l engine and a ecm. The only problem with the 02 model is the transmission, but the engine is good and starts alright. Can I go ahead with the swapping

02 Axiom has a port injected 3.5L and a GM 4L30e transmission and a 04 Axiom has a 3.5L Direct Injection engine and an Aisin AW30-40LS transmission.

The transmission in your 04 is not the same as the one in the 02
A 04 Axiom has an Aisin AW30-40LS transmission and the 02 has a GM 4L30e transmission. The are not wired the same and use a different TCM.
