P0776 2013 Toyota RAV4 Code - Pressure Control Solenoid 'B' Performance
Quick Answer
Changing from 1st to 6th is performed by the Engine Control Module (ECM) turning shift solenoid valves SL1, SL2, SL3, SL4, and SL on and off. Common causes include Low transmission fluid level, Dirty transmission fluid, Faulty Pressure Control Solenoid 'B' valve (Shift Solenoid Valve SL2). Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0776 2013 Toyota RAV4 Description
The ECM commands gear shifts by turning the shift solenoid valves on and off. According to the input shaft speed, intermediate (counter) shaft speed, and output shaft speed, the ECM detects the actual gear (1st, 2nd, 3rd, 4th, 5th or 6th gear). When the gear commanded by the ECM and the actual gear are not the same, the ECM illuminates the MIL and stores the Diagnostic Trouble Code (DTC).
What are the Possible Causes of the DTC P0776 2013 Toyota RAV4?
- Low transmission fluid level
- Dirty transmission fluid
- Faulty Pressure Control Solenoid 'B' valve (Shift Solenoid Valve SL2)
- Pressure Control Solenoid 'B' valve harness is open or shorted
- Pressure Control Solenoid 'B' valve circuit poor electrical connection
- Transmission valve body assembly is blocked
- Faulty Automatic transaxle assembly
How to Fix the DTC P0776 2013 Toyota RAV4?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

The P0776 code on a 2013 Toyota RAV4 indicates an issue with the Pressure Control Solenoid "B" Performance or Stuck Off. This code is part of the transmission control system, where the solenoid controls hydraulic pressure within the transmission to manage gear shifts and overall performance.
Possible Causes
- Faulty pressure control solenoid "B"
- Low or dirty transmission fluid
- Blockage within the transmission valve body
- Wiring issues or a poor connection in the transmission control circuit
- Transmission mechanical issues (e.g., damaged internal components)
Symptoms
- Harsh or delayed shifting
- Transmission slipping
- Reduced fuel efficiency
- Check Engine Light (CEL) on
Diagnostic Steps
- Use an OBDII scanner to confirm the code and check for any additional codes.
- Inspect the transmission fluid level and condition; low or dirty fluid can contribute to this issue.
- Check wiring and connectors associated with the transmission solenoid for any signs of damage, wear, or disconnection.
- Test the pressure control solenoid "B" to ensure it is functioning correctly.
- If solenoid issues are ruled out, further inspection of the valve body or other transmission components may be necessary.
Repair Steps
- Fluid Change: Replace the transmission fluid if it is dirty or low.
- Replace Solenoid: If the solenoid is faulty, replacing it is often necessary.
- Valve Body Inspection: Clean or replace the valve body if it has blockages.
- Repair Wiring: Address any damaged or faulty wiring or connectors in the circuit.
- Transmission Repair: In rare cases, transmission rebuilding may be needed if internal damage is found.
A transmission specialist can assist if the problem persists after basic repairs.
