While I was driving I heard a bang, then a constant knocking sound. At first thought I blew a tire because I could smell something like burning rubber. When I got home I looked under the vehicle and I could see transmission had leaked all over the exhaust. I took a couple photos of the side of the gearbox (the driveshaft going to the Front passenger tire, and it looks like something broke of the side of the gearbox. The transmission makes a horrible knocking sound, so I assume I nee to replace the entire gearbox. In Canada what is the typical cost for this fix?
