Laymans terms

This code means that the car's computer noticed something unusual when changing gears from third to second. It's like when you try to change gears on your bike and it feels a bit off.

Explanation

The transmission control module (TCM) monitors the gear ratio during shifts. If the ratio is not within the expected range when shifting from third to second gear, it triggers this code.

Technical description

P17EE indicates that the transmission control module has detected an incorrect gear ratio when shifting from the third gear to the second gear. This could be due to mechanical issues within the transmission, problems with the shift solenoids, or issues with the transmission fluid.

Symptoms

• Check Engine Light is on

• Harsh or delayed shifting

• Transmission slipping

Common Causes

• Faulty shift solenoid

• Low or dirty transmission fluid

• Mechanical failure in the transmission

Diagnosis steps

• Check the transmission fluid level and condition.

• Scan the vehicle for additional codes.

• Test the operation of the shift solenoids.

Repair procedures

• Replace or repair faulty shift solenoids.

• Flush and replace transmission fluid.

• Inspect and repair mechanical components of the transmission.

Tools required

• OBD-II scanner

• Transmission fluid dipstick
