    These are transmission codes:
    P0700 Transmission Control System Malfunction
    P0740 Torque Converter Clutch Circuit Malfunction
    Have you had the software updated in the transmission control module? These transmissions had internal problems with the valve body, and also a problem with a bushing that would go bad and contaminate the entire transmission with metal shavings, and replacement was the only option. If the transmission was rebuilt, then you should consider taking it back to the people who performed the work.

    THIS TRANSMISSION HAS SEVERAL VALVE BODY ISSUES, IF DURING THE REBUILD IT WAS NOT REPLACED AND THE COMPUTER SOFTWARE NOT UPDATED, ITS BEEN MY EXPIERIENCE THAT IT WILL NEVER PERFORM THE WAY IT WAS DESIGHND TO.
