so why was the transmission and axle replaced?
It all started with a slight clunk during a gear change while driving on Hwy 404 in Toronto. It wasn't until I got off the highway that I noticed a strong burning smell, and a faint whining noise that varied with engine RPM. At the same time, the car started to feel really sluggish.
Turns out there was a manufacturing defect with the 9 G-tronic transmission, causing oil to leak onto the exhaust. In the end, they had to order new parts from Germany (5 items total), which took almost 3 weeks to arrive.
