Shift Kit - Chevy Allison 1000 6-speed 2006–2008, BD part 1604721.
Shafts are where a transmission finally gives up once the clutches have been made to hold more than the factory intended. The input shaft twists, and it takes the rest with it.
BD's billet shafts are machined from solid rather than forged to a price, which is what lets them carry the torque a built transmission is capable of putting through them.
It is the part to fit while the transmission is apart, not after it has failed a second time.
BD list this as part 1604721.
