B&M 40263 SHIFT IMPROVER KIT - Manual (Page 12)

5.4Operate 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.
5.5Set 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). For best transmission operation, set TV
pressure as close as possible to 227 kPa (33 psi), using
the following procedure.
5.6Since 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 set TV pressure with the transmission in gear.
NOTE: Do not check or set TV pressure in PARK.
5.7Using a screwdriver or pointed tool, pry up white toggle
lever on cable adjuster located immediately behind the
throttle body cable mounting bracket. (See Fig. 14.) The
adjuster preload spring should cause the adjusting slider
to move away from the throttle body and TV pressure
should increase.
5.8Push on the slider from behind bracket until TV pressure
is 227 kPa (33 psi). While still holding slider, push down
on toggle lever as far as it will go, locking slider in position.
(See Fig. 15.) NOTE: Toggle lever must be completely
down (lying flat in adjuster assembly) to lock properly.
5.9Remove gauge tool, allowing cable to return to its normal
idle position. With engine still idling in NEUTRAL, TV
pressure must be at or near 0 kPa (0 psi) (less than 34 kPa
(5 psi)). If not, reinstall gauge and repeat Steps 7 and 8
but set TV pressure to a pressure less than 227 kPa (33
psi) but no less than 207 kPa (30 psi). Remove gauge tool
and recheck TV pressure to determine if it is at or near 0
kPa (0 psi).
Self-locking type cable Throttle Valve (TV) Control
Cable System.
5.0 L HO and SEFI Engines
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.)
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 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.
