P0762 Code: Shift Solenoid “C” Stuck On

Automatic transmission vehicles are equipped with shift solenoids that control the flow of fluid inside the transmission. If your vehicle has problems with its shift solenoids, the P0762 code or other related trouble codes can trigger. Using a scan tool to check your vehicle for any stored trouble codes can help you diagnose and fix the issue.

What Does the P0762 Code Mean?

Diagnostic trouble code (DTC) P0762 stands for Shift Solenoid ‘C’ Stuck On. Transmission fluid movement is responsible for moving the appropriate transmission components. If the shift solenoid “C” is stuck in the “on” position, then the P0762 code will trigger. This code indicates that the problem is with shift solenoid C. There are usually two or more shift solenoids inside a transmission assembly that are often designated A, B, C, etc.

Shift solenoids are spring-loaded plunger devices that regulate the flow of transmission fluid to control shifting. Automatic transmissions rely on the flow of transmission fluid to work. When they malfunction, expect to have transmission-related issues.

Note: The definition of the P0762 code can be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.

What are the Common Causes of the P0762 Code?

While the P0762 code usually means there’s a shift solenoid malfunction, it may also be caused by any of the following:

• Failed shift solenoid
• Corroded or damaged wiring
• Internal transmission failure
• Restricted hydraulic passages
• Defective transmission valve body
• Insufficient transmission fluid
• Dirty or contaminated transmission fluid
• Clogged transmission fluid filter
• Faulty PCM (rare)

What are the Common Symptoms of the P0762 Code?

Here are the common symptoms of the P0762 code:

• Transmission slipping
• Transmission gets stuck in gear
• Decreased fuel economy
• Your vehicle enters limp mode
• Illuminated check engine light

How to Diagnose the P0762 Code

The P0762 code can be caused by several issues. Identifying them can be difficult because you might need to visually inspect components like the shift solenoids, depending on the symptoms you’re experiencing. Since the transmission is difficult to access as it’s usually under the vehicle, inspecting it might need prior experience or specialist tools. It may be the best to leave the task to a trusted mechanic.
