GEARSHIFT CABLE
(1) The floor shifter lever and gate positions
should be in alignment with all transmission PARK,
NEUTRAL, and gear detent positions.
(2) Engine starts must be possible with floor shift
lever in PARK or NEUTRAL gate positions only.
Engine starts must not be possible in any other gear
position.
(3) With floor shift lever handle push-button not
depressed and lever in:
(a) PARK position—Apply forward force on cen-
ter of handle and remove pressure. Engine starts
must be possible.
(b) PARK position—Apply rearward force on cen-
ter of handle and remove pressure. Engine starts
must be possible.
(c) NEUTRAL position—Normal position. Engine
starts must be possible.
(d) NEUTRAL position—Engine
running
and
brakes applied, apply forward force on center of
shift handle. Transmission shall not be able to shift
from neutral to reverse.
THROTTLE VALVE CABLE
Transmission throttle valve cable adjustment is
extremely important to proper operation. This adjust-
ment positions the throttle valve, which controls shift
speed, quality, and part-throttle downshift sensitivity.
If cable setting is too loose, early shifts and slip-
page between shifts may occur. If the setting is too
tight, shifts may be delayed and part throttle down-
shifts may be very sensitive. Refer to the Adjust-
ments section for the proper adjustment procedure.
SPEED SENSOR TESTING
Test the speed sensor with an ohmmeter. Place the
ohmmeter leads on the terminals in the sensor con-
nector (Fig. 42).
Rotate the transmission output shaft and observe
the ohmmeter needle. The needle should deflect indi-
cating the switch is opening/closing as the rotor
moves past the sensor (Fig. 42). Replace the sensor if
the ohmmeter does not display any kind of reading.
If a digital ohmmeter is being used, the sensor
should generate an ohmmeter readout each time the
switch opens and closes.
FLOW TESTING TRANSMISSION MAIN
COOLER
Cooler flow is checked by measuring the amount of
fluid flow through the cooler in a 20 second time
period. The test is performed with the engine run-
ning and transmission in neutral. Fluid is then
pumped through the cooler by the transmission oil
pump.
(1) Disconnect cooler inlet line at transmission fit-
ting.
