2005 automatic transmission
Ocassionally having difficultly getting the transmission to shift out of the park position. I understand the shut down procedure and I'm following it clearly. This problem is doesn't happen each time which I find very confusing. Interested in knowing if anyone else has experience this problem and is there a solution or something I need to change?
Sounds like a problem with the Ignition/Park interlock switch. Take this one to your dealer and check for recalls. The Ignition/Park Interlock is designed to keep the transmission from being moved out of park without the keys in the ignition, however, if it is malfunctioning, you might experience what you are going through.
I'm having the same problem. I went to the Chevy maintenance dept this morning and they said it is more than likely the interlock switch. It cost about $22.00. That's cheaper than putting the car on a diagnostic machine at the dealer. That could cost you in upwards of $100.00. I'll soon see if it fixes the problem!
