Ok guys, doing some research on trying to swap out an LY7 for an LSX motor... I assume the engine harness and PCM will not be too awful hard to deal with, but what are my transmission options? Id like to run a 4L80E behind whatever motor I swap in, but Im not sure if there is a way to control it with a factory G8 GT Harness?

Any help would be appreciated.... there arent really any major G8 swaps happening yet it seems...
