I recently acquired a totaled 2013 ZL1 automatic from a friend(LSA engine/6l90 trans). What parts should I keep off of the car besides the engine/trans? I am not very familiar with the gen4 electronics. I know I need the engine/trans, pcm, fusebox, pedal assy, and harness. I don't have a particular vehicle that it is going in yet, I just want to cover my bases. Thanks Fellas!
