The car's computer is saying that the part that controls the gears is asking for too much power to be reduced, which might mean something isn't working right.
The Transmission Control Module (TCM) is detecting an unusually high request to reduce engine torque, which could indicate a malfunction.
This code indicates that the Transmission Control Module (TCM) has detected an excessively high torque reduction request. This could be due to a fault in the transmission system or related components, leading to improper torque management.
• Check Engine Light is on
• Poor transmission performance
• Reduced engine power
• Faulty Transmission Control Module (TCM)
• Wiring issues or poor connections
• Faulty sensors related to torque management
Transmission Control Module (TCM): An electronic component that controls the transmission's operation.
Torque: A measure of the rotational force in the engine.
• Use an OBD-II scanner to confirm the code
• Inspect wiring and connectors to the TCM
• Test the TCM and related sensors for proper operation
• Repair or replace faulty wiring or connectors
• Replace the Transmission Control Module if faulty
• Replace faulty sensors
• OBD-II scanner
• Multimeter
• Basic hand tools

Transmission System Issue
• Do not ignore the Check Engine Light
• Have the vehicle inspected by a professional
• Avoid heavy loads until the issue is resolved
Check with your vehicle's manufacturer for warranty coverage on transmission components.
This code has been associated with transmission control issues in various vehicle models, often requiring TCM updates or replacements.
Moderate – Addressing this issue soon can prevent further transmission damage.
Ignoring transmission issues can lead to safety hazards and further vehicle damage.
• Vehicle at operating temperature
• Transmission in drive mode
The Transmission Control Module is usually located near the transmission or under the hood in the engine compartment.
Q: Can I drive with a P184A code?
A: It's not recommended to drive for extended periods with this code, as it may lead to further damage.
Q: What happens if I ignore this code?
A: Ignoring this code can result in transmission failure or damage, leading to costly repairs.
