I was going for the spicer 7 speed or an eaton 8, there is a local medium and heavy truck salvage yard in Hopkinville, Ky. The guy Earl that runs the place is amazing when it comes to these IH4700 trucks. He has helped me tremendously with parts and advice. Everyone I talk to about these trucks says they auto tranny is what makes them horrible on the road. They never shift right, and are almost always in the wonrg gear for the terrain. While the 545 series Allison is a tough tranny, it just doesn't fit my driving style.
