when i parked on a slight incline, front uphill, today, it went into park easily with my foot on the brake and the engine running. i shut the engine down and let my foot off the brake. about 30 seconds later, it rolled back a short distance and "clunked" down in its bowels--then stopped and didn't move again. sure surprised me!! have i got a problem, or had it just not seated the trans lock??
