Throttle Cable

The throttle cable is adjustable on all automatic transmissions. And in each case it controls throttle pressure. Throttle pressure is an indication of load. When the throttle is depressed, the cable transfers this motion to the base of the throttle valve and moves it upward to increase throttle pressure. Throttle pressure causes the primary regulator valve to increase line pressure. As the throttle is depressed, greater torque is produced by the engine and the transmission may also downshift to a lower gear. If line pressure did not increase, slippage could occur which would result in wear of the clutch plate surface material.

Throttle pressure's affect on transmission operation differs between a hydraulically controlled transmission (non-ECT) and an electronically controlled transmission (ECT). In a non-ECT transmission, throttle pressure affects shift points and line pressure; whereas in an ECT transmission it only affects line pressure. Control of line pressure will affect the quality of the shift, not the shift points, in an ECT transmission.
