I have a 02 WRX with an automatic trans (sorry guys). It has 103k and most likely has not been changed. I have been told by my mechanic to change the trans oil and filter. When reading the maintenance manual it says the trans filter is a maintenance free part and should only be changed if damaged or leaking. I think that if you are changing the old oil you should change the ATF filter. Just want to get opinions. Also what ATF oil would you recommend.
Thanks for your input.
