I bought my 2006 Nissan Sentra auto. with 19,000 miles. 2-3 times a year the O/D light comes on and transmission down shifts while driving on city streets and on highway. The only way to solve this has been pulling over, turning off engine and restarting. Now I am at 121,500 miles. I would appreciate your advice.

How long since you had the transmission oil serviced?
