Really need to test to test turbine speed sensor,,,,vehicle speed sensor to check for output,,,,can be tested at ,Auto Zone ,,or like parts stores...solenoid pak normally doesn't have failure issues,,not to say it can't but codes that are set off,,sometimes are secondary to the real problem.....most issues start there,,,if processor doesn't see engine running,,or vehicle moving---there's no need to up-shift transmission !!!! If it sees one signal but not the other,,,things sometimes gets weird,,,those sensors are known to fail for no reason {cheap junk}..Have seen cars scrapped,,,traded ect,,,ect for a simple thing like that!!!!
