Greetings, I hope I got the right forum for my question.

A local mechanic advised me to replace the data cable/plug between the transmission and electronics box because it had oil on it. The repair was not cheap but he indicated if it was not done it would seap into the electronics and cause even more expenses.

The cable I find is just behind the fly wheel housing on the right side front
of the transmission. It has what I could call a light coating of oil and grim on it, not enough to blacken my finger. That is if it is the right cable.

I should note the car only has 37,7xx orginal miles and is driven by my wife for her 2+ miles to work and maybe some past road trips of several hundred miles. besides road dust the engine, transmisson are very clean and other oil to speak of. I did open
the electronics box and no signs of any oil or grim.

Questions:
1. is that the cable in question? if not where is it?

2. has anyone had this problem before or am I just being taken for a
unnecessary repair.

Thanks
Gary
