CLEANING AND INSPECTION (Continued)
Inspect all valve springs for distortion and col-
lapsed coils. Inspect all valves and plugs for burrs,
nicks, and scores. Small nicks and scores may be
removed with crocus cloth, providing extreme care is
taken not to round off sharp edges. The sharpness of
these edges is vitally important. It prevents foreign
matter from lodging between valve and valve body.
This reduces the possibility of sticking. Inspect all
valves and plugs for freedom of operation in valve
body bores.
When bores, valves, and plugs are clean and dry,
the valves and plugs should fall freely in the bores.
The valve body bores do not change its dimensions
with use. Therefore, a valve body that was function-
ing properly when vehicle was new, will operate cor-
rectly if it is properly and thoroughly cleaned. There
is no need to replace valve body unless it is damaged
in handling.
ADJUSTMENTS
GEARSHIFT CABLE ADJUSTMENT
Lift and rotate the gearshift hand lever into the
park (P) gate position and remove the ignition key.
This confirms the shift lever is in the gated park (P)
position.
After confirming the park gate position, turn the
ignition switch. If the starter will operate, the park
gate position is correct. Move the shift lever into the
neutral (N) position. If the starter will operate in this
position, the linkage is properly adjusted. If the
starter fails to operate in either position, linkage
adjustment is required.
(1) Park the vehicle on level ground and set the
parking brake.
(2) Place the gearshift lever in park (P) gate posi-
tion and remove key.
(3) Loosen the cable adjustment screw at the tran-
saxle operating lever (Fig. 160).
(4) Pull the transaxle operating lever fully forward
to the park detent position.
(5) Release the park brake, then rock the vehicle
to assure it is in park lock. Reset the park brake.
(6) Tighten the cable adjustment screw to 8 N·m
(70 in. lbs.). Gearshift cable should now be properly
adjusted.
(7) Verify PRNDL indicator still displays the corre-
sponding gear completely. If not, readjustment of
PRNDL may be required.
(8) Check adjustment by using the preceding pro-
cedure.
THROTTLE PRESSURE LINKAGE ADJUSTMENT
The throttle pressure rod adjustment is very
important to proper transaxle operation. This adjust-
ment positions a valve which controls shift speed,

shift quality, and part throttle downshift sensitivity.
If the setting is too short, early shifts and slippage
between shifts may occur. If the setting is too long,
shifts may be delayed and part throttle downshifts
may be very sensitive.
With engine at operating temperature, adjust idle
speed of engine using a tachometer. Refer to Group
14, Fuel System for idle speed Specifications and
adjustment.
ROD ADJUSTMENT PROCEDURE
(1) Perform transaxle throttle pressure adjustment
while engine is at normal operating temperature.
(2) Loosen adjustment swivel lock screw.
(3) To insure proper adjustment, swivel must be
free to slide along flat end of throttle rod. Disassem-
ble and clean or repair parts to assure free action, if
necessary.
(4) Hold transaxle throttle lever firmly toward
engine, against its internal stop. Tighten swivel lock
screw to 11 N·m (100 in. lbs.)
(5) The adjustment is finished and linkage back-
lash was automatically removed by the preload
spring.
(6) If lubrication is required see Group 0, Lubrica-
tion.
BAND ADJUSTMENT
KICKDOWN BAND (FRONT)
The kickdown band adjusting screw is located on
left side (top front) of the transaxle case.
(1) Loosen locknut and back off nut approximately
five turns. Test adjusting screw for free turning in
the transaxle case.
(2) Using wrench, tighten adjusting screw to 8
N·m (72 in. lbs.).
