Hello,
A month ago I purchased a golf VI version 1.4 TSI 122km. My mechanic after driving it said that it would be good to change the oil in the gearbox. I know that it is necessary to change oil in automatic transmission. As for the manual, I once heard that someone changed the oil, but from what I read on the web, it is rather not recommended. But maybe with the TSI engine, such operations should be done, I don't know. I would like to know if anyone has done such operations, or maybe someone can tell me if such operations are actually performed on manual transmissions?
