Code P1775 RAM Description
The P1775 diagnostic trouble code (DTC) indicates that the solenoid switch valve is stuck in the Torque Converter Clutch (TCC) position. The TCC is responsible for locking the torque converter to improve fuel efficiency and reduce heat buildup in the transmission. When the solenoid switch valve is latched in the TCC position, it can cause the transmission to remain in lockup mode, leading to issues with acceleration, shifting, and overall performance of the vehicle. This can result in poor fuel economy, harsh shifting, and even transmission overheating if left unresolved. The solenoid switch valve is a crucial component in the transmission system, and any malfunction can have significant effects on the vehicle's drivability.
Common Causes of P1775 RAM
- Faulty solenoid switch valve
- Wiring or electrical connection issues
- Low transmission fluid level or quality
- Internal transmission mechanical problems
- Faulty TCC solenoid
Symptoms of P1775 RAM
- Harsh or delayed shifting
- Engine stalling at stops
- Decreased fuel efficiency
- Transmission overheating
- Illumination of the Check Engine Light
How to Fix P1775 RAM
- Perform a diagnostic scan to confirm the P1775 code and identify the exact cause of the issue.
- Inspect the solenoid switch valve and surrounding components for any signs of damage or wear.
- Test the electrical connections and wiring related to the solenoid switch valve for continuity and proper voltage.
- Replace the solenoid switch valve if it is found to be faulty or stuck in the TCC position.
- Clear the DTC and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P1775 RAM
The cost of repairing a P1775 code can vary depending on the specific cause of the issue and the labor rates in your area.

Frequently Asked Questions about P1775 RAM Code
What does the OBDII code P1775 mean for a RAM vehicle?
P1775 indicates that the solenoid switch valve is latched in the Torque Converter Clutch (TCC) position, which can affect the transmission's ability to function properly.
What are the common symptoms of code P1775 in a RAM vehicle?
Symptoms may include transmission slipping, difficulty shifting gears, reduced fuel efficiency, or the transmission going into limp mode.
What causes the P1775 code to be triggered?
Common causes include a malfunctioning solenoid switch valve, low transmission fluid, clogged transmission fluid passages, or a faulty transmission control module (TCM).
Can low transmission fluid cause the P1775 code?
Yes, low or degraded transmission fluid can cause the solenoid switch valve to malfunction, leading to the P1775 code.
How do I diagnose the P1775 code in my RAM vehicle?
Diagnosis involves checking the transmission fluid level and condition, inspecting the solenoid switch valve, testing the transmission control module, and scanning for additional trouble codes.
Is it safe to drive with the P1775 code?
Driving with this code is not recommended, as it can lead to further damage to the transmission and reduce vehicle performance.
How do I fix the P1775 code on a RAM vehicle?
Repairs may include replacing the solenoid switch valve, cleaning or flushing the transmission, topping off or replacing the transmission fluid, or repairing wiring and connections.
What should I check first when troubleshooting the P1775 code?
Start by checking the transmission fluid level and condition, as low or dirty fluid is a common cause of this issue.
Can a faulty TCM cause the P1775 code?
Yes, a malfunctioning transmission control module can misinterpret or fail to properly control the solenoid switch valve, triggering the P1775 code.
How much does it typically cost to fix the P1775 code in a RAM vehicle?
Repair costs vary but can range from $150 to $500, depending on whether the issue is with the solenoid, transmission fluid, or electronic components like the TCM.
