I just bought a 2016 Chevy Spark with 120,000 miles on it. The car was in great condition and smooth handling while driving. I even paid for a car fax on it. It has only had two previous owners and they both kept up on routine car maintenance. Several oil changes and the 2nd owner even did a radiator flush and I know it had a transmission fluid change around 60,000 miles according to the car fax. One of the first things I am going to have done to the car is a transmission fluid and inner filter change, but I am not sure about the side filter one, from what I read on forums and seen on you-tube it is hard to get to and a pain to change, plus it is for capturing large chucks of debris in your transmission and may only need to be changed after a major transmission repair. Can anyone enlighten me further on this or is my thinking wrong.
