Hello, you all have a successful, healthy and accident-free year 2013. I need your help here my problem: I have had a C70 II D5 Diesel 132 KW Geartronik 5 Gang Bj 05.2007 The vehicle I bought with 57000 Km and have the following problem: The automatic switches rough and very bad, I sometimes feel I’m driving only in the converter, yes sounds stupid but is so.. accordingly the consumption is high. Had now a similar vehicle as a replacement vehicle and the gearbox switched faultless, therefore the comparison is possible. In some posts I could read similar problems and also from the partial solution by changing the grated oil. I have a visit to the “friendly” who took care of it immediately and controlled the oilstan (if i.o.) but after a smell test the “friendly” meant the oil would be burned and should be changed well. I have read a lot of addogeld and I did not find a detailed instruction. Some write of oil change (if i.o.o.) but let go of oil is done with a new fill of oil. Therefore, the oil must be well.
