Servus all over, I would like to renew my automatic transmission oil after 230,000 km, contrary to Mr. Volvo’s other statements (problems don’t exist…). What happened before, you don’t know. With the method, how it comes out of the Volvo book (downloaded here somewhere in this forum), which is essentially in line with the Haynes book, I come only a few liters, much less than here some indicate. In principle, what goes out, also has to go in again. How does this come about? Is this the case? I read everything from 12 to 15 l. I ask because the oil is not just a gift and is certainly too bad to stand around. It probably won’t get better over the years. By way of the official method I would have added a cleaner before the rinse. The method itself is trivial (two out of five screw keys at Haynes ) I plan the Fuchs ATF 5000 SL to use (Dexron IIe), despite the fact how many claim that subsequent Dexron classifications are backward compatible. As I read at the star dock gate (but about other oils) a lot is claimed… The Dexron IIe is the official oil. In another place here the fox oil was attested best quality. I wonder if a flushing by TE is as cheap as some indicate what it fills for an oil quality. Thank you for your answers. -helmut
