This summary uses the existing diagnostic information shown in full below.
This code means that a part in your car's transmission, like a switch, isn't working right. It's supposed to help change gears smoothly, but it's stuck or not working well.
The P0796 code indicates that the transmission control module (TCM) has detected a problem with the pressure control solenoid C, which is not performing as expected or is stuck in the 'off' position.
The pressure control solenoids in an automatic transmission are responsible for controlling the hydraulic pressure needed to shift gears. Solenoid C is one of these components, and when it fails to operate correctly, it can lead to improper gear shifts or transmission performance. The TCM monitors the solenoid's performance and sets the P0796 code when it detects an issue.
• Harsh or delayed gear shifting
• Transmission slipping
• Reduced fuel efficiency
• Check Engine Light illuminated
• Faulty pressure control solenoid C
• Transmission fluid issues (low level, dirty, or contaminated)
• Wiring problems or poor electrical connections
• Faulty transmission control module (TCM)
TCM: Transmission Control Module
Solenoid: An electromechanical device that controls fluid flow in the transmission
• Check the transmission fluid level and condition.
• Inspect the wiring and connectors to the solenoid.
• Test the solenoid for proper operation.
• Scan for additional codes that may indicate related issues.
• Replace or repair the faulty solenoid.
• Change or flush the transmission fluid.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the TCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools
• Transmission fluid service tools

Transmission Performance Issue
• Avoid driving aggressively until the issue is resolved.
• Schedule a diagnostic check with a professional mechanic.
Check your vehicle's powertrain warranty, as transmission components may be covered.
The P0796 code has been a common issue in vehicles with automatic transmissions, particularly those using electronically controlled solenoids.
Moderate – Addressing this issue promptly can prevent further transmission damage.
Driving with a transmission issue can lead to further damage or unsafe driving conditions.
• Vehicle at operating temperature
• Transmission in drive
The pressure control solenoid C is located inside the transmission, usually accessible by removing the transmission pan.
Q: Can I drive with a P0796 code?
A: It's not recommended to drive for long periods with this code, as it can cause further transmission damage.
Q: How do I reset the P0796 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is fixed, it should not return.
