is it some sort of hybrid? All our PCs are either Allison equipped or if it’s a Ford it has the 6R140.. both are conventional automatic transmissions.
it would slip out into what would be reverse if the engine is running. Without the engine running there is no pressure to activate solenoids because the pump is not turning and the converter is not spinning
So it could slip into neutral? That is usually the problem I think. Which is why the driver should be using the handbrake.
