Re: Transmission behavior while coasting
If you put it in second and then just let off the brake and waited for gravity to take over, chances are the transmission torque converter was not engaged. It probably needs either throttle input or some speed differential for the torque converter to lock up.
I bet the times you could not reproduce it you gave it a little gas to get moving first.
