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 5.0L and 5.0L HO (302 CID) SEFI engine uses an Air
Bypass (ISC) that does not affect throttle position. Therefore,
idle automatic setting does not affect TV cable adjustment.
6. Self-locking TV Cable Linkage Adjustment
6.1Remove air cleaner cover and inlet tube from throttle
body inlet to access throttle lever and cable assembly.
6.2Using a wide-blade screwdriver, pry grooved pin on cable
assembly out of grommet on throttle body lever. (See
Fig. 20.)
6.3Using a small screwdriver, push out white locking tab.
6.4Check to ensure plastic block with pin and tab slides
freely on notched rod. If it does not slide freely, the white
tab may not be pushed out far enough. (See Figs. 21 &
22.)
6.5While holding throttle lever firmly against its idle stop,
push grooved pin into grommet on throttle lever as far as
it will go. NOTE: While pushing pin into grommet, make
sure you do not move throttle lever away from idle stop.
(See Fig. 23.)
6.6Install air cleaner cover and air inlet tube.
7. Self-locking TV cable adjustment using TV Control
Pressure.
7.1Attach TV pressure gauge (0-60 PSI) T86L-70002-A or
equivalent to TV pressure tap (See Fig. 8).
7.2Obtain Cable TV Gauge tool T86L-70332-A or equiva-
lent.
7.3Insert tapered end of the tool between the crimped slug
on the end of cable and plastic notched rod, also on end
of cable assembly. Push in Cable TV Gauge Tool T86L-
70332-A or equivalent forcing the crimped slug away
from the plastic rod. Ensure gauge block is pushed in as
far as it will go. (See Fig. 24.)
WARNING: THIS PROCEDURE REQUIRES WORKING
IN CLOSE PROXIMITY TO THE EGR SPACER ASSEM-
BLY WHICH MAY BE HOT.
7.4Operate engine until normal operating temperature is
reached. The transmission fluid temperature should be
approximately 38-72
o C (100-150 o F). Do not make pres-
sure check if transmission fluid is cold or too hot to touch.
7.5Set parking brake and place shift selector in NEUTRAL.
With gauge tool in place and engine idling in NEUTRAL,
the TV pressure should be between 207 and 276 kPa (30
and 40 psi). NOTE: Do not check or set TV pressure in
PARK.
7.6If TV pressure meets specification in Step 5, remove
gauge tool allowing cable to return to its normal idle
position. With engine still idling in NEUTRAL, TV pres-
sure must be at or near zero (less than 34 kPa (5 psi)).
7.7If TV pressure does not meet specification in either or
both Steps 5 and 6, remove gauge tool and readjust cable
as outlined under Self-locking TV Cable Adjustment.
Then repeat steps 3 through 6.
7.8If TV pressure still does not meet specification, it will be
necessary to modify adjustment as follows.
7.9Remove gauge tool and pry grooved pin out of grommet
on throttle lever. (See Fig. 25.)
7.10Mark or measure location of plastic block on notched
rod. (See Fig. 26.)
7.11Push out locking tab. (See Fig. 27.)
7.12Using mark or measurement on plastic block as a
reference, move plastic block towards throttle body
mounting bracket to raise TV pressure, or move it away
from bracket to lower TV pressure. Push in white locking
tab to lock block in position. (See Fig. 28.)
7.13Insert grooved pin back into grommet. (See Fig. 29.)
7.14Check TV pressure. Refer to Steps 3 through 6. NOTE:
For best transmission function, the TV pressure should
be set as close as possible to 227 kPa (33 psi) in
NEUTRAL with gauge tool installed. Since the TV
pressure goes up approximately 14 kPa (2 psi) when the
shift lever is moved from NEUTRAL to a forward gear,
this will result in a TV pressure setting near the desirable
241 kPa (35 psi) in forward gear. Do not attempt to
check TV pressure with the transmission in gear.
When the gauge tool is removed, the TV pressure
should drop to less than 34 kPa (5 psi). If the TV pressure
does not drop to less than 34 kPa (5 psi), reset the TV
pressure to a value less than 227 kPa (33 psi) with gauge
tool installed but no less than 207 kPa (30 psi). Verify
that the TV pressure is less than 34 kPa (5 psi) with
gauge tool removed.
