TRANSMISSION THROTTLE VALVE CABLE
ADJUSTMENT
The transmission throttle lever is operated by an
adjustable cable (Figs. 4 through 12). The cable ad­
justment lock button is located in the retainer por­
tion of the cable (engine-end). The adjustment
procedure for gas and diesel engines is the same.
A correctly adjusted throttle valve cable will cause
the throttle lever on the transmission to move simul­
taneously with the throttle control lever from the idle
position. Proper adjustment will allow simultaneous
movement without causing the transmission throttle
lever to either move ahead of, or lag behind the ac­
celerator lever.
Throttle cable adjustment can be checked on the
vehicle. It is recommended that cable adjustment
condition be verified before proceeding to the cable
adjustment procedure.
Checking Throttle Cable Adjustment
(1) Turn ignition key to OFF position.
(2) Remove air cleaner on gas engines.
(3) On diesel engines, verify that fuel injection
pump accelerator linkage is at curb idle position (Fig.
4).
(4) On gas engines, verify that lever on throttle
body is at curb idle position. Then verify that trans­
mission throttle lever (Figs. 5 and 6) is also at idle
position.
(5) Slide cable off attachment stud on throttle body
or injection pump lever.
(6) Compare position of cable end to attachment
stud on throttle body lever (Fig. 7):
(a) Cable end and attachment stud should be
aligned (or centered on one another) to within 1
mm (0.039 in.) in either direction.
(b) If cable end and attachment stud are mis­
aligned (off center), cable will have to be adjusted
as described in following adjustment procedure.
(7) Reconnect cable end to attachment stud. Then
with aid of a helper, observe movement of transmis­
sion throttle lever and lever on throttle body.
(a) If both levers move simultaneously from idle
to half-throttle and back to idle position, adjust­
ment is correct.
(b) If transmission throttle lever moves ahead of,
or lags behind throttle body lever, cable adjustment
will be necessary. Or, if throttle body lever prevents
transmission lever from returning to closed posi­
tion, cable adjustment will be necessary.
Throttle Valve Cable Adjustment Procedure
(1) Turn ignition switch to OFF position.
(2) Remove air cleaner on gas engines.
(3) Disconnect cable end from attachment stud on
control lever (Fig. 8).

(4) Verify that transmission throttle lever is in
fully closed position. Then be sure lever on throttle
body is at curb idle position.
(5) Locate cable lock button. Button is part of cable
retainer at engine end of cable.
(6) Press cable lock button inward to release cable.
Lock button only has to move about 2 mm (0.070 in.)
to release cable in adjuster head.
(7) Center cable end on attachment stud to within
1 mm (0.039 in.) and release lock button (Fig. 8).
(8) Check cable adjustment. Be sure transmission
throttle lever and lever on throttle body, move simul­
taneously and as described in cable adjustment
checking procedure.
THROTTLE WALVE CABLE REPLACEMENT
(1) Raise vehicle.
(2) Disconnect throttle valve (TV) cable at trans­
mission lever (Figs. 10 and 11).
