The San Gabriel Mountains formed at what is essentially a kink in the San Andreas Fault. Along this fault the Pacific Plate slides northward while the North American Plate slides southward. At the kink, a small portion of the North American Plate juts out north of part of the Pacific Plate. The motion of the two plates rams them together at this location, thrusting sections of rock upward to form the San Gabriel Mountains.

Although they aren't common, yes, transform faults can give rise to mountains. Most transform faults take place between oceanic crust, but an easy-to-see example is that of the San Andreas Fault giving rise to the San Gabriel Mountains.
The San Gabriel and San Bernardino Mountains are part of the Transverse Ranges in Southern California.

Mountain passes are gaps that allow for easier foot travel from one side of the mountains to the other side of the mountains. The Cumberland Gap (through the Appalachian Mountains) was long used by the Native Americans before the arrival of Europeans, who 'found it' around 1750. See link below. The Cajon Pass (through the San Bernardino mountains and the San Gabriel Mountains) was used by a group of Mormon settlers traveling from Salt Lake City to Southern California in 1851. See link below.
