Causes and Solutions for Toyota P0776 Code
| Cause | Solution |

Shift Solenoid Valve SL2 Remains Open
The Toyota P0776 code is commonly caused by a shift solenoid valve SL2 remaining open. This means the valve is not responding to the signals the transmission control module sends. This can cause the transmission to be unable to shift to the 5th and 6th gears. If this is the case, the shift solenoid valve SL2 must be replaced.
Shift Solenoid Valve SLT Remains Open or Closed
The Toyota P0776 code can also be caused by a shift solenoid valve SLT remaining open or closed. This means the valve is not responding to the signals the transmission control module sends. This can cause the transmission to be unable to shift to the 5th and 6th gears. If so, the shift solenoid valve SLT must be replaced.

Valve Body is Blocked (Brake Control Valve)
The Toyota P0776 code can also be caused by a blocked valve body (brake control valve). This can cause the transmission to be unable to shift to the 5th and 6th gears. If so, the valve body must be cleaned or replaced.
Automatic Transmission (Clutch, Brake or Gear, etc.)
The Toyota P0776 code can also be caused by an automatic transmission issue such as a faulty clutch, brake, or gear. This can cause the transmission to be unable to shift to the 5th and 6th gears. If this is the case, the transmission must be repaired or replaced.
