The rebuilder has agreed to send me another solenoid pack to install in the ATX. They told me I would receive it today (it's getting awfully late). They told me that replacing it myself would not void the warranty. I have already purchased a new Shift Lever Position Sensor. Even though I hate to just throw parts at a problem, I would rather replace it now while I have access to it and eliminate that as a possible cause of the shift problems I am encountering.
