P2708 Fault Code

Shift Solenoid F Stuck On

• What does that mean?
• Symptoms
• Causes
• Solutions

The P2708 fault code indicates that the transmission control system has detected that the Shift Solenoid F is stuck in the 'on' position. This solenoid is responsible for controlling the flow of transmission fluid, which is essential for engaging and disengaging gears during vehicle operation. When it gets stuck, it can lead to various transmission issues, impacting the overall performance of the vehicle.

What are the symptoms of the P2708 code?

Drivers may notice several symptoms associated with this fault code, including:

• Harsh or erratic shifting of the transmission
• Delayed engagement when shifting from park to drive or reverse
• Warning lights on the dashboard, such as the check engine light
• Slipping or loss of power during acceleration
• Transmission overheating due to improper fluid flow.

What causes the P2708 code?

Several factors can cause the Shift Solenoid F to become stuck. Common causes include:

• Faulty shift solenoid itself
• Electrical issues such as short circuits or wiring problems
• Low transmission fluid levels
• Contaminated transmission fluid leading to solenoid malfunction
• Problems with the Transmission Control Module (TCM) that affect solenoid operation.

How to fix P2708?

To resolve the P2708 code, the following steps should be taken:

• Perform a thorough diagnostic to confirm the presence of the fault code and rule out other potential issues.
• Inspect the shift solenoid and associated wiring for damage or shorts.
• Check transmission fluid levels and condition; replace or replenish if necessary.
• If the solenoid is found to be faulty, it should be replaced.
• Clear the fault code and perform a test drive to ensure the issue has been resolved.
