Why does my drive gear no longer work?
I have a 2010 Nissan Murano. I gave someone a boost to get their car started. At first the positive cable was put on the negative and it gave off a spark. We then put cables on correctly. the other vehicle started. then 2 hours later I went to the bank with the car still on. When I got back into the car i noticed the service engine light was on then when I put the gear in reverse it would not move. I tried twice and then it went into reverse and then into drive but as I was leaving out the drive no longer worked. The cars engine stayed on the drive and reverse does nothing. I had the car towed to my home. Previously I NEVER had any trouble or indication that something was wrong with the vehicle. the service engine light remains on and the car starts up fine as ussual but shifting the gears into drive and reverse does nothing The car has 80,000 miles. Ive had it for 2 years. Does anyone have suggestions?
