B&M 40227 TRANSPAK - Manual (Page 14)

On Thunderbird/Cougar vehicles with column shift
and 3.8 L engines, there is also a bellcrank assembly
mounted on the transmission bell housing in the area of
the TV lever and bracketry holding the cable in the upper
bell housing area.
As the throttle is moved from idle to wide-open throttle
(WOT), the TV control cable pulls the transmission TV
control lever from idle to WOT. Return of the cable and
transmission lever toward idle is accomplished by the
return spring on the transmission end of the cable assem-
bly. This spring and the end of the cable assembly is
protected by a flexible rubber boot. The transmission
external TV control lever actuates the internal TV control
mechanism which regulates the TV control pressure. The
travel of this lever is controlled by stops internal to the
transmission.
The TV control cable is set and locked to its proper
length during initial assembly when the grooved pin on the
upper end of the cable assembly is inserted in the grom-
met on the throttle body lever. To release the cable
locking mechanism, it is necessary to pry the grooved pin
out of the grommet and push out the white locking pin. The
take-up spring at the end of the cable assembly tensions
the cable and takes up the slack in the system. When the
grooved pin is reinserted in the grommet, the white
locking tab is pushed in, automatically locking the cable to
its correct length. When the cable is locked, the take-up
spring plays no part in the operation of the system.

The throttle valve (TV) control cable system consists of a
cable attaching grommet on the throttle body throttle
lever, the TV control cable assembly, the external TV
control lever on the transmission, and cable mounting
brackets at the throttle body and transmission. (See Figs.
16, 17, 18 & 19.)
