700R4 Throttle Valve (TV) Cable Adjustment

GARD Pro Not Registered

The Throttle Valve Cable is attached to the throttle linkage. When the throttle is depressed, the cable is “pulled” progressively with throttle position. In addition to providing forced downshifts (kickdown), and progressively later (higher speed) upshifts at higher throttle settings, the throttle valve also adjusts main line pressure in the transmission. Operating a transmission with the TV cable out of adjustment, can, not only produce early, or late upshifts, but incorrect line pressure, as well. What this means, in simple terms, is that TV pressure that is too low, will produce main line pressure that is also too low, and will eventually “burn” the transmission clutches.
