(5) Pull cable conduit toward rear of vehicle until
wiper is completely retracted into end of conduit fit­
ting (Fig. 3). Then release cable lock button.
(6) Raise vehicle for access to transmission throttle
valve lever (Fig. 4).
(7) Rotate throttle valve lever toward front of ve­
hicle until ratcheting sound (from cable) stops.
C A U T I O N : D o not rotate the throttle valve lever be­
yond the idle stop. The lever, valve and manual le­
ver shaft will be damaged if rotated too far.
(8) Remove spacer and check cable adjustment.
Throttle valve lever should begin to move at same
time lever on MPI throttle body moves off idle posi­
tion.
(9) Lower vehicle.

TRANSMISSION THROTTLE CABLE
ADJUSTMENT-CUMMINS DIESEL ENGINE
A cable is used to operate the transmission throttle
valve on models with a Cummins diesel engine. Ca­
ble adjustment is controlled by a locking pawl on the
cable sheath (Fig. 5).
The rear of the cable is connected to the transmis­
sion throttle valve lever. The forward end of the ca­
ble is attached to a pin on the engine throttle cam

(Fig. 6). Rotation of the throttle cam (by the engine
throttle cable), actuates the cable and throttle valve
lever for downshifts.
A 4.57 m m (0.180 in.) diameter g a u g e is n e e d e d
to c h e c k and adjust the throttle valve cable o n
diesel models. U s e a micrometer a n d inside cali­
pers, a drill of the correct diameter, or fabricate

(1) Run engine until it reaches normal operating
temperature.
(2) Verify t h a t engine hot idle speed is within
specifications. Adjust hot idle rpm if necessary.
(3) Check cable adjustment with gauge as follows:
(a) Verify t h a t throttle lever is seated against
low idle stop screw (with accelerator pedal fully re­
leased).
(b) Check clearance between rear of cable actuat­
ing pin and end of slot in throttle valve cable (Fig.
6).
(c) Clearance should be 4.57 mm (0.180 in.) as
measured with gauge.
(d) If adjustment is OK, no further action is re­
quired. However, if clearance is greater or less
then specified, adjust cable as described in follow­
ing steps.
