DESCRIPTION AND OPERATION (Continued)
AUTOMATIC TRANSMISSION SHIFTER/IGNITION
INTERLOCK
The Shifter/Ignition Interlock, is a mechanical
cable operated system (Fig. 1). It interconnects the
automatic transmission floor–mounted shifter to the
steering column ignition switch. The interlock system
locks the floor–mounted shift lever into the PARK
position whenever the ignition switch is in the LOCK
or ACCESSORY position. When the key is in the
OFF or RUN position, the shifter is unlocked and
will move into any position. Also the interlock system
prevents the ignition switch from being turned to
LOCK or ACCESSORY position, unless shifter is in
the PARK position.

GEARSHIFT AND PARKING LOCK CONTROLS
The transaxle is controlled by a lever type gear-
shift incorporated within the console. The control has
six selector lever positions: P (Park), R (Reverse), N
(Neutral), and D (Drive), 2 (Second), and 1 (First).
The parking lock is applied by moving the selector
lever past a gate to the (P) position. Do not apply
the parking lock until the vehicle has stopped;
otherwise, a severe banging noise will occur.
TORQUE CONVERTER CLUTCH SOLENOID WIRING
CONNECTOR
If the solenoid wiring connector is unplugged, the
torque converter will not engage (Fig. 2).
GOVERNOR
The governor can be serviced by removing the
transaxle oil pan and valve body assembly. The gov-
ernor can be unbolted from the governor support and
removed from the transaxle for reconditioning or
replacement.

When cleaning or assembling the governor, be sure
the governor valves move freely in the bores of the
governor body.
DIAGNOSIS AND TESTING
31TH TRANSAXLE DIAGNOSIS AND TESTS
Automatic transaxle malfunctions can be caused by
four general conditions:
(1) Poor engine performance
(2) Improper adjustments
(3) Hydraulic malfunctions
(4) Mechanical malfunctions
Diagnosis of these problems should always begin
by checking the easily accessible variables: fluid level
and condition, gearshift cable adjustment, and throt-
tle pressure cable adjustment. Then perform a road
test to determine if the problem has been corrected
or that more diagnosis is necessary. If the problem
exists after the preliminary tests and corrections are
completed, hydraulic pressure tests should be per-
formed
31TH HYDRAULIC TROUBLE CODE CHARTS
The following charts should be used to help diag-
nose hydraulic or mechanical faults in the transaxle.
ROAD TEST
Prior to performing a road test, check the fluid
level and control cable adjustments.
During the road test, the transaxle should be oper-
ated in each position to check for slipping and any
variation in shifting.
If vehicle operates at high speeds, but has poor
acceleration, the converter's overrunning clutch may
be slipping. If acceleration is normal, but high throt-
