Code P0964 2015 Chevrolet Silverado Description

The pressure control solenoid 2 is part of the control solenoid valve assembly which has no serviceable parts. The normally high-pressure control solenoid 2 regulates and directs the pressure control solenoid 2 oil pressure to the 3-5 reverse clutch regulator valve and 3-5 reverse clutch boost valve. Increasing pressure control solenoid 2 pressure increases pressure to the 3-5 reverse clutch. The Transmission Control Module (TCM) varies the current to the pressure control solenoid 2 through a low side driver. Decreasing the current to the pressure control solenoid 2 increases pressure control solenoid 2 oil pressure by closing OFF the solenoid exhaust port. Increasing the current to the pressure control solenoid 2 decreases pressure control solenoid 2 oil pressure by opening the solenoid exhaust port. Pressure control solenoid 2 power is supplied by the Transmission Control Module through a high side driver. The high-side driver protects the circuit and components from excessive current flow. If excessive current flow is detected, the high side driver will turn OFF. When the fault is corrected, the high-side driver will reset.
The Diagnostic Trouble Code (DTC) will be set when the Transmission Control Module detects an open on the pressure control solenoid valve 2 control circuit for 1 s.

2. What are the common symptoms of code P0964 in a 2015 Chevrolet Silverado?

Symptoms may include harsh or delayed gear shifts, transmission slipping, reduced fuel efficiency, or the Check Engine Light illuminating.

3. What causes the P0964 code to appear in a 2015 Chevrolet Silverado?

Common causes include a faulty pressure control solenoid, damaged wiring or connectors in the control circuit, or issues with the transmission control module (TCM).

4. Can I drive my 2015 Chevrolet Silverado with a P0964 code?

Driving with this code is not recommended, as it can lead to further transmission damage or unsafe driving conditions due to poor shifting performance.

5. How do I diagnose a P0964 code on my 2015 Chevrolet Silverado?

Diagnosis typically involves inspecting the solenoid circuit for damaged wiring or connectors, testing the pressure control solenoid for proper operation, and checking the TCM for faults.

6. How do I fix the P0964 code on a 2015 Chevrolet Silverado?

Repairs may include replacing the faulty pressure control solenoid, repairing damaged wiring or connectors, or reprogramming or replacing the TCM if necessary.

7. How much does it cost to repair a P0964 code on a 2015 Chevrolet Silverado?

Repair costs vary, but replacing a pressure control solenoid typically costs $150–$400, while TCM repairs or replacements could range from $500 to $1,200, depending on labor and parts.

8. Can a low transmission fluid level cause a P0964 code in a 2015 Chevrolet Silverado?

While low transmission fluid itself may not trigger P0964, it can cause transmission performance issues that may indirectly contribute to solenoid or circuit problems.

9. Does the P0964 code always mean the pressure control solenoid is faulty?

No, the issue could also stem from damaged wiring, poor electrical connections, or a malfunctioning TCM.

10. Will clearing the P0964 code with a scan tool fix the problem?

Clearing the code will reset the Check Engine Light temporarily, but the underlying issue must be diagnosed and repaired to prevent the code from returning.
