Diagnosing Jeep Grand Cherokee Shifting Problems

There is a common issue with shifting on a number of Jeep Grand Cherokee models as they age and their mileage increases. The shifting problem usually surfaces when the vehicle is first started and the engine and transmission are cold. You're often still able to drive the vehicle, but it only operates in one or two gears. For example, you may find that you're only able to drive the car in the automatic transmission's third gear, only being able to select the other two gears when you shift the transmission manually.

The most common cause of transmission problems is the easiest to fix: check the fluid level in the transmission and restore it to the proper levels. Very often, this will solve the problem. But Jeep Grand Cherokees seem especially prone to more serious transmission problems, and some owners are quite vexed at their inability to determine the causes. 

On models with OBD (onboard diagnostics) systems, a code scanner plugged into the diagnostic port gives you a reading to help identify the problem. However, easy solutions still exist even if you don't have a code reader.

How to view Transmission Diagnostic Flash Codes 

  1. Turn ignition key ON and OFF three times, finally leaving the key in the ON position. Leave the Overdrive Off Switch in the normal overdrive (ON) position.
  2. Immediately begin counting the number of flashes displayed by the Overdrive Off Switch indicator lamp. There will be two sets of flashes, separated by a pause. The number of flashes in each group indicates the first and second digit in the flash codes.
  3. A code 55 identifies the end of flash code transmission.

How to Interpret Transmission Diagnostic Flash Codes 

Below, you'll find the list of Transmission Fault Codes for Jeep automatic transmissions.

  • Code 11 - No Engine Speed Sensor Signal
  • Code 12 - No Output Shaft Sensor Signal
  • Code 13 - No Vehicle Speed Sensor Signal
  • Code 14 - Governor Pressure Sensor Signal
  • Code 15 - Throttle Position Signal
  • Code 16 - Transmission Temperature Sensor
  • Code 17 - Overdrive Off Switch Circuit
  • Code 18 - System Voltage Out of Limits
  • Code 19 - Standby Voltage Out of Limits
  • Code 21 - Governor Pressure Solenoid Circuit
  • Code 22 - 3-4 Solenoid Circuit
  • Code 23 - Torque Converter Clutch Circuit
  • Code 24 - Overdrive Off Lamp Circuit
  • Code 25 - EEPROM Checksum Error
  • Code 26 - Governor Pressure Sensor Offset Drift
  • Code 55 - End of Message

You may or may not be skilled enough to actually fix the problems indicated by the flash codes yourself, but you're better-armed with an understanding of where the issues lay as you seek help from a mechanic.
