Need some opinions on an allison 5 speed auto.. Would this work with 375 hp truck with a 600-700 bushel grainbox? Lots of guys run 275 -330 hp with 6 speed allisons but 5 is uncommon here. Im wondering how it would get around the field and on the hiway with 4.11's and 22.5 rubber.. Power would definately be enough.. All opinions are greatly appreciated.
