1994 Renault Laguna 6 cyl Two Wheel Drive Automatic 110,000 miles
Every time I drive around for a while the transmission will be shifting up and down unnecessarily and the service light will show, and sometimes it never shift back for the right speed making the engine kind of heavy when I want to take off. I really need help on this
You need to have the vehicle plugged into renault's diagnostic computer or equivalent to locate the exact cause of the fault .. repost with the fault codes for a better diagnosis and repair information !!
