P0776 Scion 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 Scion 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 Scion?
- 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 Scion?
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.
