I just flushed my transmission and put a magnefine filter on the line & now the engine light is on. I have never had this before. I did the exact same to my TL magna with no problems. Car seems to be driving great battery is not too old. Everything seems to be hooked up right any suggestions would be appreciated.

I drove the car at varying speeds for the next 20 minutes and arrived home. Opened the side gate heading for the shed to look under lights and restarted the car and the light is now off. The car is running great, putting the transmission cooler on in the next couple of days. Can anyone explain this engine light?

No one can really explain the light, best thing to do is plug scan tool in and find out what code it produces..
