my 96 seville with 147k is showing the "service transmissions" warning and the check engine light has also come on. this first occurred at about 10pm last night. The thing that is bothing me is the engine shift into gear and preforms as normal. all 4 gears preform as should and smooth as ever. I am not aware of the tranny over heats nor should it. i never go over 75ish and was only going 45 at the time the message first showed. i am going to have the codes pulle don my lunch break and will post. i was just wondering if this could be an encoded service msg showing based on mileage? and if thats not the case should i be preparing to refinance my home to fix this?
