On the W202 chassis the shift delay switch-over valve is next to the overvoltage relay under the plastic cover at the rt rear of the engine area.
However if the car has a check engine lamp with code P1 700, it doesn't mean that this valve is bad. Usually it means that the control pressure cable isn't being controlled properly.
