For 1990-2009 cars only

If electrical power is interrupted with the transmission operating in reverse range, resulting in neutral operation, main pressure is directed through shift valve 3 to shift valve 2. Because shift valve 2 stays stroked due to the "latching" effect of pressure on two different diameter lands, main pressure is blocked from reaching the manual selector valve. If the manual selector valve is moved to Neutral (N) or a forward range, the transmission remains in neutral.

If electrical power is interrupted with the transmission operating in reverse range, resulting in neutral operation, the engine may be shut down and restarted to attain neutral, third and reverse operation.
