Oh I am also going to buy a new fuel filter - does not look like its ever been changed according to receipts. Car is quiet and runs smoothly. Transmission gear slightly stiff when it gets a warm when i want to put it back in to park. Or when I need to put it to drive from park when engine is warm. I have been reading articles on the net and what I am doing now is that when I park up, i turn the engine off and then put it in park. Also when engine is warm and when I want to start car, I put car in neutral and start it in neutral before putting in to drive. Seems to work better. No problem when transmission is cold. You can see now why I want to change the transmission oil. Any thoughts on that?
