I now have 235000 miles on this truck

First, let me say that I have a 1996 Dodge pick up with a Cummins Diesel. I have used your oil and transmission additives since I bought this truck new, and I now have 235000 miles on this truck, which is low for the engine but the transmission should have died miles ago. This truck has towed everything from snowmobiles to fifth wheel campers from coast to coast and hauled loads it shouldnt have. I attribute the longevity of the transmission to your product.  I have used it in other vehicles and have had the same luck with your engine and transmission products.
