I have an update on the story. I just found out that when my transmission went out, the tow truck company may have towed the car incorrectly to BMW. They towed the truck with the front wheels on the ground and the back wheels raised. I have been scouring the forum and have been reading that if the car isn't towed with all four wheels on the ground, it can directly result in a blown transfer case. Also, the axle leak that Sears was replacing was one from the half shaft. They claim that they didn't have anything to do with the transfer case when handling the axle leak, but they had to have some handling of the spline, correct? If anyone has any suggestions or any thoughts it would be much appreciates.
