If electrical power is interrupted with the transmission operating in Reverse (R) and the throttle was above approximately 20 percent and did not drop to 10 percent before the power interruption, resulting in Neutral operation, and if the manual valve is moved to a forward range, main pressure goes through shift valves E and D and the manual valve, to the 4-5 clutch, applying the clutch. The 3rd, 5th, and Reverse clutch remains applied. Applying the 4-5 clutch and the 3rd, 5th, and Reverse clutch produces fifth range operation.

If electrical power is interrupted with the transmission operating in Reverse (R) range, and the throttle is 10 percent or lower and did not rise to 20 percent before the power interruption, resulting in Neutral operation, the engine may be shut down and restarted to attain Neutral, third and Reverse operation.
