Before starting let's see P396B repairing process steps:

• Qualified technicians will begin by using a scan tool to access P396B code stored in the ECU.
• Technicians will note P396B code present and any freeze frame data associated with them.
• After all, if you sure the engine trouble is finished, the code will be cleared.

The fluid pressure sensor provides the PCM with the data necessary to monitor the transmission performance. If the fluid pressure increases, the electrical voltage reading from the pressure sensor will increase; if the pressure decreases, the voltage decreases.

This process helps the mechanic narrow down the exact cause of the issue. If the transmission fluid fix did not cause the code to disappear from the PCM, then next step is to inspect the electrical components, and to continue working through possible repairs until the correct issue is found.
