300M Tranny Issue

I have a 2002 300M.  The transmission is jumping into 2nd gear when at a stop and it will jump down from 4th gear into 2nd when coming to a stop.  It will only do this when you drive for at least 15-20 minutes.  Also the Autostick options will be zero'd out.  I am getting the P 0700 code.  I replaced the input/output sensors but didn't correct he problem.  Any thoughts?  Will a dirty transmission filter cause this type of issue or does it sound like more of a Solenoid Pack replacement?  Let me know if you can help...
