Great point, Dibbons.
The entire function of the automatic transmission is electronic now, right? Even the engagement of the transmission parking pawl? Maybe the computer "thought" the parking pawl was engaged?
Thanks, Kern. --I too tend to come into a thread with a thought that may help having not read the thread through.
I drove my 6SP man. trans. car to the dealer and the code they pulled up mentioned a "sticking pawl"
I will indeed do my best to get what information I can from them when I go back in the morning.
