I have a 04 Honda Civic with an automatic transmission with 104,000- it was bought used recently and not sure if the transmission fluid has been changed before but assuming not.
I have heard that you are not supposed to changed the transmission fluid if it has not been maintained at regular intervals (I believe 60,000 and then 30,000 intervals after the 60,000)
I would feel better if I changed it just for peace of mind but do not want to do more harm to the car. I do not noticed any problems with the transmission.
What approach do you guys think is best- just leave it or change it.
I also gave a 02 Cavalier with a transmission without a dipstick. The car has 58,000 (is prior salvage). The transmission is only supposed to be serviced by dealers. It does have a very slow leak. Should I take that into the dealer and get it changed or just leave it?
