I bought my car in Jan 2002 and currently have 25K miles on it. I recently just took my car in for a minor maintenance and the service man suggest I do the entire transmission fluid flush? My car is not even 2 years old yet so I was wondering if he's right or just trying to take $200 from me. I don't have that much knowledge about this car stuff so any suggestion will be appreciated.
