Moin dear forum, have to my “new” sweetheart (C70-T5 1998) another question which imposes itself on me ^^. I now own the car for 2 weeks and have adopted “you” with a mileage of only 70 tkm. My question: Makes it sense to change the transmission oil, since it is already 15 years old. From the point of view of mileage it is certainly talkable. I have to say that the automatic actually also switches very well… and how is it so nice: Don ́t touch running systems! Thank you for your opinions, Gerald
