Allison 10L1000 Torque Converter

  • Unlike our transmissions, No Zone Diesel must charge our customers an upfront core fee on torque converters.  Core fee is refundable to the customer upon return of usable core.

    Over the years we have experienced a mass number of customers that have not returned their cores.  So, we are forced to charge $400 for a torque converter core.  Again, these fees will be refunded to the customer upon inspection.
