I understand your concern but i'm planning on keeping this truck for a better part of my life and will put countless more miles on it so if you do know of an adapter that would informtion would be great!

Some quick math if i drove 6240 miles a year and that transmission is 2,000 dollers (aprox). It would pay for itself in 6.6 years if it gave me 12MPG. And i plan on keeping on that truck for many times that number of years.

So in the long run that transmission would be a money saving investment.
