P0762
UniversalP0762 indicates a malfunction in the Shift Solenoid C circuit, specifically detecting that the solenoid is stuck in the 'on' position, preventing proper gear engagement or disengagement.
High SeverityThis code signifies that the Shift Solenoid C in your vehicle's transmission is continuously activated. This prevents the transmission from shifting gears correctly, leading to poor driving performance and potential damage to the transmission.
⚠️ Before You Begin (Safety First)
Always ensure the vehicle is safely supported on jack stands if working underneath. Disconnect the negative battery terminal before performing any electrical or mechanical work to prevent accidental starting or electrical shorts. Allow the engine and transmission to cool down completely before touching any components.
Common Symptoms
- Check Engine Light illuminated
- Transmission slipping
- Harsh shifting or delayed shifts
- Transmission stuck in one gear (limp mode)
- Reduced fuel economy
- Vehicle may not move at all
Common Causes
- Faulty Shift Solenoid C (stuck open or shorted internally)
- Clogged transmission fluid passages
- Contaminated or low transmission fluid
- Wiring harness issues (chafed, broken, or shorted wires)
- Damaged transmission valve body
- Malfunctioning Transmission Control Module (TCM)

Diagnostic Steps
- Check transmission fluid level and condition. Ensure it is at the correct level and free from burning smell or excessive debris.
- Inspect the wiring harness and connectors leading to the transmission for any visible damage, corrosion, or loose connections.
- Clear the DTCs and test drive the vehicle to see if the code returns.
- If the code persists, the transmission pan may need to be dropped to access and visually inspect or test the Shift Solenoid C.
- If testing confirms the solenoid is faulty, replace the Shift Solenoid C.
- Refill with fresh transmission fluid and install a new transmission filter.
- Perform a diagnostic scan and clear codes, then test drive the vehicle.
👨🔧 When to Call a Professional
If after initial checks you are not comfortable with dropping the transmission pan, dealing with transmission fluid, or diagnosing electrical issues within the transmission, it is highly recommended to consult a certified transmission specialist. Ignoring this issue can lead to catastrophic transmission failure.
Commonly Asked Questions
What exactly does Shift Solenoid C do?
Shift Solenoid C is an electro-hydraulic valve inside your transmission that controls the flow of transmission fluid to engage or disengage specific gears, allowing the transmission to shift smoothly.
Can I drive with a P0762 code?
It is not recommended to drive with a P0762 code for an extended period as it indicates a serious transmission issue. Driving can cause further damage to the transmission and may leave you stranded.
Is replacing a shift solenoid a difficult repair?
It can be an advanced DIY repair, as it often requires dropping the transmission pan, draining fluid, and working with sensitive internal transmission components. Special tools and knowledge of transmission systems may be needed.
How much does it cost to fix a P0762 code?
The cost varies depending on the vehicle and labor rates. A solenoid itself can range from $50-$250, but labor for replacement, including fluid and filter, can range from $300-$800 or more, especially if a professional shop is involved.
Can low transmission fluid cause a shift solenoid code?
Yes, low or contaminated transmission fluid can certainly contribute to shift solenoid malfunctions or erratic behavior, as proper fluid pressure and lubrication are crucial for their operation.
