Hi guys looking for some advice regarding my autobox a340e iv looked through various posts with many different answers.Iv owned my jspec na just over a year it's coming up to 85k I had a partial oil change on the gear box shorty after buying it as i dont have any history regarding maintenance. I have just discoverd theres a filter inside the gearbox that should be replaced.The car atm drives spot on gear changes are smooth and change when they should. Do I leave it and carry on driving it or should I get it changed and potentially stop any problems that may occur in the future.
