1994 Renault Laguna

Transmission problem
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 !!

hope this helps
