Automatic shiftlock, checking
function (automatic
transmission)

The automatic shiftlock uses an electric
solenoid to lock the selector lever in
Park or Neutral. Depressing the foot
brake with the ignition on energizes the
solenoid, allowing the lever to be
moved into a drive gear. The solenoid
is energized only when the engine
speed is below 2,500 rpm and the
vehicle speed is below 3 mph. The
solenoid is mounted in the right-hand
side of the selector lever housing.

Automatic shiftlock prevents drive gear
selection until the brake pedal is
depressed.

-

With engine running and car
stopped, place selector lever in
Park or Neutral.

-

Without depressing brake pedal,
check that selector lever is locked
in position Park or Neutral.

-

Depress brake pedal firmly.
Solenoid should be heard to
energize.

-

Check that selector lever can now
be moved out of Park or Neutral.

Note:

The next test should be performed in an
open area with the parking brake on
and with extreme caution.

-

With selector lever in Park or
Neutral and brake pedal
depressed, raise engine above
2,500 rpm. Check that selector

lever cannot be moved out of Park
or Neutral.

If any faults are found check the
electrical operation of the shiftlock
solenoid and check for wiring faults to
or from the transmission control
module (TCM). See

610 Electrical

Component Locations

and Electrical

Wiring Diagrams.

Note:

The solenoid is controlled via the TCM,
using brake pedal position, engine
speed, and road speed as controlling
inputs.
