c. Front Governor (Gl) Circuit (blue, black— fig. 2-5). The front governor (G1) circuit functions as described in paragraph 2-15c d. Rear Governor (G2) Circuit (green, black— fig. 2-5). The rear governor (G2) circuit functions as described in paragraph 2-15d except that in- creased G2 pressure, in the absence of in- termediate-low inhibitor pressure, has forced the low-intermediate shift plug, shift valve, and blocker plug upward. This allows main pressure to be directed to the intermediate-high shift valve bore. Low-range clutch pressure is exhausted when the low-intermediate shift valve is upward. e. Intermediate-Range Clutch Circuit (red, yellow—fig. 2-5). At the intermediate-high shift valve, main pressure. is connected to the in- termediate-range clutch pressure line. This applies the clutch. j. Throttle Valve (TV) Circuit (blue, yellow—fig. 2-5). The throttle valve (TV) circuit functions as describe in paragraph 2-15f. 2-15
