This code means there's a problem with a part in the car that helps change gears. It's like a switch that isn't working right.
The P1740 code indicates an issue with the clutch solenoid circuit, which is responsible for helping the transmission shift gears properly.
The P1740 code is triggered when the Powertrain Control Module (PCM) detects a problem with the clutch solenoid circuit's range or performance. This solenoid is crucial for managing the torque converter clutch engagement, affecting gear shifting and transmission efficiency.
• Check Engine Light is on
• Poor transmission performance
• Decreased fuel efficiency
• Faulty clutch solenoid
• Wiring issues in the solenoid circuit
• Malfunctioning transmission control module
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to verify the code.
• Inspect the clutch solenoid and related wiring for damage.
• Test the transmission control module for faults.
• Replace the faulty clutch solenoid.
• Repair or replace damaged wiring.
• Reprogram or replace the transmission control module if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Dodge Ram
• Chrysler Town & Country
• Jeep Grand Cherokee
• Regular transmission fluid checks and changes
• Routine inspection of transmission components
• Avoiding harsh driving conditions
Transmission Performance Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if unsure.
• Consider regular maintenance to prevent future issues.
Check with your vehicle manufacturer; transmission components may be covered under powertrain warranty.
The P1740 code has been associated with torque converter clutch issues in older vehicle models, particularly in certain Chrysler and Dodge vehicles.
Moderate – Addressing this code promptly can prevent further transmission damage.
Driving with a transmission issue can lead to unsafe driving conditions. It is recommended to address the issue as soon as possible.
• Vehicle at operating temperature
• Transmission in drive mode
The clutch solenoid is located within the transmission assembly, often accessible by removing the transmission pan.
Q: Can I drive with a P1740 code?
A: It's possible to drive, but it's not recommended as it can lead to further transmission damage.
Q: How do I clear a P1740 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue persists, the code may return.
