2007 Chevy Impala 6 cyl Front Wheel Drive Automatic 75000k miles
This is a possible solution which worked for me. My 2007 Impala LTZ was stuck in PARK. The engine and door locks worked but the shift lever would not move and the silver button which is depressed to move the shift lever would not depress. After traying several options, I pushed the Traction Control Button and the problem was resolved. Don't know why this worked. My closest Chev dealer's only suggestion was to call roadside assistance and get it towed in.
UPDATE: It worked only once. Now I have to take it in. I wonder if this is a power train issue or GM has a recall for the problem. I see several people are having the same problem
