Yea me either. I even pull mowing trailers in the summer quite often with it. When I dropped the pan I was sure the tranny was toast. The only thing strange is that the lock up worked fine for probably the first 6 months that I had the truck and then the lock up quit working. That is why I am confused with why the transmission was the way it was or why the t/c lockup quite working. Also, the check engine light isn't on or anything.
