Fig. 8 Throttle Lever & Bracket Assembly Alignment
The T.V. cable should not be thought of as an automatic downshift cable. It controls line pressures, shift points, shift feel, part throttle downshifts, and
detent downshifts. The function of the cable is similar to the combined functions of a vacuum modulator and detent downshift cable. The T.V. cable
operates the throttle lever and bracket assembly, Figs. 6 and 7.
1.
Stop engine.
2.
Depress readjust tab and move slider through fitting, away from lever assembly, until slider stops against fitting. Release readjust tab.
3.

binding.

Road test vehicle. If delayed or only full throttle shifts still occur, proceed as follows:
a. Remove oil pan and inspect throttle lever and bracket assembly, Fig. 8.
b. Check T.V. exhaust valve lifter rod for distortion, or binding in control valve assembly or spacer plate.
c. Make sure T.V. exhaust check ball moves up and down in conjunction with lifter.
