(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 center
of handle and remove pressure. Engine starts
must be possible. (b) PARK position-Apply rearward force on center
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. Transmission throttle valve cable adjustment is
extremely important to proper operation. This adjustment
positions the throttle valve, which controls shift
speed, quality, and part-throttle downshift sensitivity.
If cable setting is too loose, early shifts and slippage
between shifts may occur. If the setting is too
tight, shifts may be delayed and part throttle downshifts
may be very sensitive. Refer to the Adjustments
section for the proper adjustment procedure. Before road testing, be sure the fluid level and control
cable adjustments have been checked and
adjusted if necessary. Verify that diagnostic trouble
codes have been resolved.
Observe engine performance during the road test.
A poorly tuned engine will not allow accurate analysis
of transmission operation.
Operate the transmission in all gear ranges. Check
for shift variations and engine flare which indicates
slippage. Note if shifts are harsh, spongy, delayed,
early, or if part throttle downshifts are sensitive.
Slippage indicated by engine flare, usually means
clutch, band or overrunning clutch problems. If the
condition is advanced, an overhaul will be necessary
to restore normal operation.
A slipping clutch or band can often be determined
by comparing which internal units are applied in the
various gear ranges. The Clutch and Band Application
chart provides a basis for analyzing road test
results.Gearshift cable

Event Data Recorder (EDR)
This vehicle is equipped with an event data recorder
(EDR). The main purpose of an EDR is to record, in
certain crash or near crash-like situations, such as an air
bag deployment or hitting a road obstacle, data that will
assist in understanding how a vehicle's systems performed.
The EDR is d ...
