the transmission, and the cable mounting brackets at the
throttle body and transmission. (See Figs. 11 & 12.)
On 3.8 L EFI Thunderbird/Cougar vehicles, 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 (same as 5.0 L
Thunderbird/Cougar vehicles with column shift).
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 assembly. 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 by pushing down on the locking lever
at the throttle body end of the cable assembly. When the
lever is unlocked, the cable is released for adjustment. The
take-up spring at this end of the cable automatically tensions
the cable when released. With the slack taken up and the
locking lever pushed, the take-up spring plays no part in the
operation of the system.
Under normal circumstances, it should not be necessary
to alter or readjust the initial setting of the TV control cable.
Situations requiring readjustment of the TV control cable
include maintenance involving the removal and/or replace-
ment of the throttle body, transmission, TV cable assembly
or installing a new main control assembly. Readjustment of
the TV control cable would also be necessary to correct
complaints of poor transmission shift quality that would have
been caused by a misadjustment of the TV control cable.
When the TV control cable is properly set, the transmis-
sion TV control lever will be at its internal idle stop (lever to
rear as far as it will travel) when the throttle lever is at its idle
stop.
Idle Speed Affect on TV Control Cable
The EFI (Electronic Fuel Injection) engine uses an Air
Bypass (ISC) that does not affect throttle position. There-
fore, idle automatic setting does not affect TV cable adjust-
ment.
5. Manual locking cable adjustment using TV Control
Pressure.
5.1Attach TV pressure gauge (60 PSI) with hose T86L-
70002-A or equivalent to TV pressure tap (See Fig. 8).
5.2Obtain Cable TV Gauge tool T86L-70332-A or equiva-
lent.
5.3Insert tapered end of the tool between the crimped slug
on the end of cable and plastic cable fitting that attaches
to the throttle lever. (See Fig. 13.) Push in Cable TV
Gauge Tool T86L-70332-A, or equivalent forcing the
crimped slug away from the plastic fitting. Ensure gauge
block is pushed in as far as it will go.
WARNING: THIS PROCEDURE REQUIRES WORKING
IN CLOSE PROXIMITY TO THE EGR SPACER ASSEM-
BLY WHICH MAY BE HOT.

pressure setting near the desirable 241 kPa (35 psi in
forward gear. Do not attempt to set TV pressure with
the transmission in gear. Turning the screw in will raise
the pressure 10.3 kPa (1.5 psi) per turn. Backing-out the
screw will lower the pressure. If equipped with idle speed
control, some “hunting” may occur and an average
pressure reading will have to be determined. If the
adjusting screw does not have enough adjustment range
to bring TV pressure within specification, adjust rod at the
transmission.
4.7Remove gauge block, allowing TV lever to return to idle.
With engine still idling in NEUTRAL, TV pressure must be
less than 34 kPa (5 psi). If not, back-out adjusting screw
until TV pressure is less than 34 kPa (5 psi). Install gauge
block and check that TV pressure is not below 207 kPa
(30 psi).
