  • Technical Details

    • Chevy Allison 1000 Shift Kit
    • Custom Rebuild Only

The Allison 1000 is a great transmission, but it has its shortcomings, particularly in high-performance, heavy-duty use applications. BD can help improve the life of your transmission as well as improve its performance with one of our modified Allison valve bodies. First, all of the mating surfaces are lapped to remove surface irregularities that can cause oil “cross flow”, clutch pack pressure loss, slippage,  irregular shifting and error codes. Then, we install new trim valves that allow the mainline pressure to be increased, which creates more clamping force on the clutch plates.
