Heavy duty transmission upgrade

Enhance Transmission to the Next Level

Thanks to the triple clutch converter, valve body recalibration kit (recalibration kit does not change shift points, only increases clutch holding power), converter flow valve, and upgraded C1, C2, C3 and C4 clutches and Kolene steels. When you're ready to take your Allision transmission to the next level of durability and reliability, upgrade your Allision with PPE's Stage 4R Transmission Upgrade Kit.
