    Is the transmission acting any differently and have you checked the oil level?

    yes checked the level and yes it was low...like 1-1/2 quarts. top it off the the correct level and did a test run and codes came back. Im thinking the solenoid pack went out due to the low level.

    Looks like these codes are common with a line pressure sensor fault.

    Make sure all of your electrical connectors on the transmission are good.

    The first code is a torque convertor code which is concerning.

    Most P07xx codes generally show up when your truck is about to spend a lot of money for you.

    P0740 means your TCC is not locking up properly, this could be due to low fluid level, but if the code is continuing you may have a hard part malfunction.
