Hello,
I have a 99 Grand Prix. Car runs like a gem. Drove this morning and no problems. Parked in lot for the day (very very cold out) started at end of day and drove 35 feet and it was like car slipped into neutral, no gears nothing anywhere. No slipping just gone. Stopped and shut off, restarted and did the same. Drove like a million bucks for 35 ft and poof. Did this for around 5 miles. While moving the 35 feet tranny is strong and perfect and then nothing. Feels electrical or linkage wise but not sure. Thanks
