since the engine only came with automatic, you will have to do some trickery regardless to get the engine to run properly. the auto trans does not have a separate TCU from the factory.
I'm no expert but I believe it's as simple as making the ECU think you are in park or neutral, via the shifter or the wiring.

are you doing a manual swap in an LS400? or in another car altogether?
