    Manufacturer's Part Number:
    1030471

    High horsepower engines require modifications to their powertrain to prevent the transmissions from failing. A stock transmission has limited clutch material and it's holding ability can be improved by increasing the amount of clutch-applied pressure by reworking the stock valve body.

    A new manual valve was created, new springs and port sizes have been developed, and new governor piston dimensions and adjustments have been made. These valve bodies have large ports for better flow rates to cool the converter in lock-up as well as improving the time to evacuate the converter for quicker clutch apply time. Each valve body is tested with the Answermatic 2000 Tester before it leaves BD's shop.

    Note: Price includes a refundable core charge. Core must be shipped directly to BD Diesel in original container with in 30 days for core refund. Core charge will be refunded by BD Diesel after core has been received. Core return instructions are included with product, see product description for details.
