TD7G - the 1st gear work but with no power - the 2nd gear work good - the 3rd gear do not work at all any suggestion where to start?
Are you French? Take too, long to explain how I know, why I care. I own a TD7G, went through it in winter of 2016 fixed everything, painted it. I haven't had the transmission apart, but I have manuals. My son mentioned someone in your situation, I think you are talking to him.
