Customer Concern: MIL on and code P0700 in the Powertrain Control Module (PCM).
Tests/Procedures: 1. This code means that there is a trouble code stored in the Transmission Control Module (TCM) and the TCM requests the MIL be turned on.
2. Use a scan tool check for codes in the TCM.
You will not be able to retrieve TCM codes with a generic code reader. You will have to use a full enhanced scanner. Most likely it is the trans solenoid pack. As to the P0138 do this.
Tests/Procedures: 1. Refer to TSB 18-031-02. The TSB refers to reflashing the Powertrain Control Module (PCM).
