My Chevy Silverado 2500HD is the largest truck I have ever owned. I thought that the rough ride just came natural do to the heavy duty springs and shocks. So I have noticed my transmission leak getting worst. I decided to crawl under the truck again. This time not for the exhaust. I wanted to try and find the leak. Well, I reached up and grabbed my drive shaft to pull myself under. That is when I noticed the rear tranny mount is torn and separated. I just hope it has not destroyed my seal.
