Allison’s 1000 and 2000 Series Transmissions for School Buses or Trucks


J.C. Transmission has performed all the necessary corrections on the 1000 and 2000 series and torque converters.


We’ve made changes on the HD-1 series, which can now resist 400 HP to 800 HP. Other changes can be performed to achieve 1200 HP. The valve body calibration has been modified to eradicate P1711 and P0872 codes.


Here at J.C. Transmission, we continually strive to improve our products to enhance durability.
