Hello there, Craig!
Seems like you’re dealing with some serious transmission-related trouble. Here’s what these codes mean:
* P0746 – Pressure Control Solenoid "A" Performance/Stuck Off
* P0776 – Pressure Control Solenoid "B" Performance/Stuck Off
* P0965 – Pressure Control Solenoid "B" Control Circuit Low
Possible Causes:
1.) Low or dirty transmission fluid - Low or contaminated transmission fluid can cause solenoid issues.
2.) Faulty pressure control solenoids – Solenoids regulate hydraulic pressure. If they fail, shifting problems occur.
3.) Wiring or electrical issues – Damaged wiring, bad connections, or a failing transmission control module (TCM) can trigger these codes.
4.) Valve body problems – Debris or internal failure in the valve body can block fluid flow.
5.) Failing transmission pump – A weak pump may cause pressure control issues.
Symptoms to Expect: - Hard or erratic shifting
- Slipping gears
- Limp mode activation
- Delayed engagement when shifting into gear What to Do Next: A.) Check transmission fluid – Ensure it’s at the proper level and in good condition.
B.) Inspect wiring and connectors – Look for damage or corrosion.
C.) Test solenoids – They might need replacement if they’re sticking.
D.) Consider a TCM check – If all else checks out, the transmission control module could be faulty.
E.) Worst case, internal transmission failure – A rebuild might be needed if the codes persist after repairs.
Recommendations:
*** Diagnosis: Use an OBD-II scanner to identify all stored codes. Inspect transmission fluid levels and quality, wiring, connectors, and solenoids.
*** Repairs: Address each code systematically. Replace faulty solenoids or repair wiring issues as needed. Ensure the transmission fluid is clean and at the correct level.
*** Consult a Professional: Due to the complexity of transmission issues, consulting a certified mechanic is advisable to avoid further damage and ensure accurate repairs.
Summary These codes suggest multiple issues within your vehicle's transmission system, involving both solenoid performance and circuit integrity. A thorough diagnosis by a professional is crucial to identify and address all problems effectively.
