Finding Neutral
Hate to bring this up again but Can the C8 be in neutral and stay in neutral for a length of time with the ignition off. I follow procedure in the manual and can exit vehicle and move it but green ignition light stays on, engine not running. Am I missing something or is the neutral function only good for a short period of time. Would like to leave it in neutral push it on the 2 post lift then roll it back when finished. Those of you that have a 2 post lift know what a PIA it is to get in and out of vehicle when in lift position.

Following as well because I like to push (by hand) my car back and forth in the garage to make room sometimes, rather than starting it up and then having to run it for 20+ min to ensure it gets up to full operating temp.
Very used to doing this in my C5 Z06 (manual) but haven't been able to figure it out with the C8 Z06.

I don't know for sure but I think there needs to be constant current to be flowing through a solenoid to keep the parking pawl from engaging. So the battery would go dead after a while. Someone could try putting the car in neutral and disconnecting the battery to see what happens.

So if the car is already off, is there a way to put it in neutral without having to start the engine?
I don't want to start the engine because then you have to run it for 20+ minutes to burn off the excess fuel in the oil from the cold starts.

I wonder how it taps into the lines? Looking at the diagram above, the filter mounts to the side of the transmission and looks as if it might be fed directly from the pump. Would the electric pump be added, or would it replace the gear driven pump? Either way it almost seems like a transmission mod might be necessary.

But is a transmission mod necessary to allow the extra pump to tap into the transmission hydraulic lines? Meaning the E-ray transmission assembly will be slightly different from a Stingray transmission? I'm just observing the input to the filter is actually a opening directly against the side of the transmission case - and the mechanical filter feeds it somehow through that opening. So, assuming the electric pump also pumps through the filter - it will need to tap into something inside of the case where the mechanical pump resides. Perhaps they have all already been designed to receive the extra electric pump with the necessary taps.
