This summary uses the existing diagnostic information shown in full below.
The car's transmission isn't getting enough pressure to work properly. It's like trying to ride a bike with flat tires.
The transmission control module has detected a loss of hydraulic pressure in the transmission system.
The P0944 code indicates that the Transmission Control Module (TCM) has detected a loss of hydraulic pressure in the transmission system. This pressure is necessary for the proper operation of the transmission, including gear engagement and shifting. A loss of pressure can be due to a leak, a faulty pump, or other issues affecting the hydraulic system.
• Transmission slipping
• Delayed or harsh shifting
• Check Engine Light illuminated
• Low transmission fluid level
• Faulty transmission pump
• Leaking transmission lines or seals
Transmission Control Module (TCM): An electronic device that controls the transmission's functions.
Hydraulic Pressure: The pressure created by fluid in the transmission system to enable gear shifts.
• Check the transmission fluid level and condition.
• Inspect for leaks in the transmission system.
• Test the transmission pump for proper operation.
• Refill or replace transmission fluid.
• Repair or replace leaking lines or seals.
• Replace faulty transmission pump.
• OBD-II scanner
• Transmission fluid level gauge
• Hydraulic pressure tester

Moderate
• Chrysler 300
• Dodge Charger
• Jeep Grand Cherokee
• Regularly check and maintain transmission fluid levels.
• Inspect for leaks periodically.
• Service transmission as per manufacturer guidelines.
Transmission System Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional as soon as possible.
Check if the transmission system is covered under the vehicle's powertrain warranty.
This code has been associated with vehicles experiencing transmission issues due to hydraulic pressure loss, often related to fluid leaks or pump failures.
High – Loss of hydraulic pressure can lead to severe transmission damage if not addressed promptly.
Driving with a malfunctioning transmission can be dangerous and may cause further damage to the vehicle.
• Engine running
• Transmission at operating temperature
The hydraulic pressure unit is located within the transmission housing.
Q: Can I drive with a P0944 code?
A: It's not recommended to drive with this code as it can lead to further transmission damage.
Q: How can I prevent a P0944 code?
A: Regular maintenance and checking for leaks can help prevent this issue.
