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. Open carburetor lever to full throttle stop position to automatically adjust cable, then release carburetor lever and check cable for sticking or binding.
4. 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.
d. Make sure lifter spring holds lifter rod up against control valve assembly.
e. Make sure T.V. plunger is not stuck.
f. Inspect transmission for correct throttle lever to cable link.
