Ok Guy's I posted in the general area about this and got no response so i will try it here. I have a 96 Sentra that has 180k on it and i am going through the car to make it fit for comuting again. I was wondering how the tranys are and how long theyb are good for? I would like to service it if thats ok but I don't want to disturb it and have things start to go wrong.(Benn here before). The fluid is not burnt but does l;ook a bit worn. Should I or shouldn't I service it?? I tis the od type trany. Also is it better to drive the car in od or only use the Od for the highway or over 50??
