On a 1978 El Camino, the vacuum line from the modulator valve typically connects to the intake manifold. This connection allows the modulator valve to receive vacuum signals, which help control the transmission shift points based on engine load and throttle position. Proper functioning of the vacuum line is essential for smooth transmission operation and performance. If the vacuum line is damaged or disconnected, it can lead to erratic shifting or transmission issues.
