thank you for the input. good to know also that the drain is 17mm. will work from that to fit my tools.
on the search i found several options. i just was intrigued by the difference in shapes and what goes at the other end of the 14mm hex.
i conclude that what goes at the other end is what fits your equipment best.
i find hard to believe that there is no data available (to my knowledge) about the sizes and location, even if i searched extensively.
eventually i found a drawing showing the location, so with that and the sizes of both plugs i can do.
still, with so many thousands of xf with manual transmissions around, this basic data should be easily available for us who do work on our cars. especially something so simple as changing transmission oil.
once again, thank you for the data on the 17mm.
