So old faithful (faithful to break at least) is having problems again (2009 Chevy Malibu).
The gear shift intermittently won't shift into Park. It will shift out and between any other gears with no problem.
Currently, I can leave the car in Neutral, turn the engine off, leave the emergency break on, and leave the key in the ignition. This is dumb, but the alternative is leaving it in neutral with the engine on, so I'll take it. The engine will turn on / off in neutral (so it's not the neutral safety switch / ignition).
Ideas on what to inspect / what to test? I'd like to leave swapping the transmission as a last resort.
