As far as the keyless go (push button start) from the late model car goes, I really doubt you can make that work. You need all of the harnesses connected to the network related to the anti theft, up to and including the fuse box in the engine compartment. I know Bob (twisted fish) had a hell of a time getting support on the programming for his NAG-1. The 545RFE has much less aftermarket support than the NAG-1. My vote would be for a man trans or going for a 4L80E swap. There are so many headaches swapping this stuff since chrysler isn't helpful on the programming end. Unless you keep everything stock i.e. stock computers, stock harnesses and stock internals you may find yourself heavily dependent on someone (quite possibly not local to you) for programming your stuff. I wish we had the aftermarket support the ford and gm guys have, but we don't...
