+1, and its not the transmission, its the TCM, so if you end up needing to purchase a TCM (cant find one with the transmission), then purchase one from a vendor that sells it as a 6th unlocked TCM..
the allison 3060 transmission is always 6 gears.. just a matter of the Transmission computer allowing it to use all gears.. (allison transmissions use a separate computer from the engine computer.. called a TCM)
