Is Honda dealer telling the truth? I have owned a 2003/53 Honda Jazz from new. Like my previous Honda Civic, it has proved been a fantastic car and very reliable. My local main dealer tells me I need to get the transmission oil changed at quite a cost. The car has done only 28,000 miles and I don't remember ever having to have to do this before. If your car is manual, such a change is a very good idea to avoid potential problems with gearbox bearings. If it's a CVT-7, it's absolutely essential because the fluid (and microfilter) should be replaced every three years or so.
