If the steering wheel is equipped with remote radio
controls, disconnect the connector from the clock-
spring. Release the connector by depressing the tang
as shown (Fig. 38), then slide the connector apart.

CAUTION: Do not bump or hammer on steering col-
umn or steering column shaft when removing steer-
ing wheel from steering column shaft.CAUTION: When installing steering wheel puller
bolts in steering wheel, (Fig. 40) do not thread bolt
into steering wheel more than a half inch. If bolts
are threaded into the steering wheel more than a
half inch they will contact and damage the clock-
spring.

PARK/NEUTRAL POSITION
SWITCH
DIAGNOSIS AND TESTING - PARK/NEUTRAL
POSITION SWITCH
The park/neutral starting switch is the center ter-
minal of the 3 terminal switch. It provides ground for
the starter solenoid circuit through the selector lever
in only Park (P) and Neutral (N) positions.
(1) To test switch, remove wiring connector from
switch and test for continuity between center pin of
switch and transaxle case. Continuity should exist
only when transaxle is in Park or Neutral.
(2) Check gearshift cable adjustment before replac-
ing a switch which tests bad.
REMOVAL
(1) Unscrew switch from transaxle case allowing
fluid to drain into a container. Move selector lever to
Park, then to Neutral position, and inspect to see the
switch operating lever fingers are centered in switch
opening.
INSTALLATION
(1) Screw the switch with a new seal into trans-
axle case and tighten to 33 N´m (24 ft. lbs.). Retest
switch with the test lamp.
(2) Add fluid to transaxle to bring up to proper
level.
(3) The back-up lamp switch circuit is through the
two outside terminals of the 3 terminal switch.
(4) To test switch, remove wiring connector from
switch and test for continuity between the two out-
side pins.
(5) Continuity should exist only with transaxle in
Reverse position.
(6) No continuity should exist from either pin to
the case.Fig. 184 Measuring Pump Outer Gear-to-Pocket

DESCRIPTION
The torque converter clutch (TCC) solenoid is fas-
tened to the transaxle valve body, and its connector
protrudes through the transaxle case (Fig. 222).
OPERATION
The torque converter clutch solenoid is responsible
for controlling application of the torque converter
clutch. It is controlled by the Powertrain Control
Module (PCM), which determines when conditions
are acceptable for torque converter lock-up.
REMOVAL
(1) Remove valve body from transaxle. (Refer to 21
- TRANSMISSION/TRANSAXLE/AUTOMATIC -
31TH/VALVE BODY - REMOVAL)
(2) Remove three (3) torque converter clutch sole-
noid-to-valve body screws (Fig. 223).
(3) Remove torque converter clutch solenoid (Fig.
223). Note orientation of plug and spring.
