TDI Tiptronic Transmission started to shift eratically from time to time. Make appointment to have it checked. They say it needs new transmission even though it now works fine. Checked on internet for answers. Found a parts jobber in the US that suggests that he has see lots of them that are just down a little oil. VW tries to make people think it is impossible for customer to service these transmissions. I found a web site by googling VW Jetta Transmission fluids by Blau parts that says different.Has anyone had any luck with this method? I do know where to put oil into this Tranny and where to take it out. Not sure where to check level yet. Also the access pan is on the front of this Tranny and not on the bottom like in the illustration. The cost of the Transmission with installation is out of the question as far as I am concerned. Almost $6000 CA. I think the VW dealer is trying to put one over on me and the Car only has 97000 odd KM on it.
