Gear Shift Control Module B Overtemperature

Where it lives

For P2DA3, the part to look at first is the module named here.

Check these first

• Gear shift control module B running hot
• Low or degraded transmission fluid
• Restricted cooling to the shift module
• A failed module internal temperature sensor
• Heavy towing or stop and go load

What to do next

1. Read gear shift control module B internal temperature
2. Check the transmission fluid level and condition
3. Inspect cooling to the shift module
4. Test the module internal temperature sensor
5. Replace shift module B if it keeps overheating
6. Clear the code and retest
