solenoid valve in the valve housing directs hydraulic pressure to the lock cylinder, which moves the piston within the cylinder
and releases the park lock pawl at the rear of the transmission by means of a connecting rod. The solenoid on the lock cylinder
is energized and locks the cylinder piston in the unlocked position. Additional locking of the piston is achieved with ball
catches within the lock cylinder.
When park is selected, the solenoid on the lock cylinder is de-energized, the ball catches are released and the piston is free to
move in the lock cylinder. The solenoid in the valve housing is also de-energized. The spring loaded parking disc pulls the
cylinder piston in the park direction which allows the park disc to move on its mounting. This movement is transferred via the
connecting rod to parking pawl, which is engaged in the park lock gear.
If an electrical failure occurs, the park lock can be manually released by means of an emergency park release lever located in
the floor console. The lever is connected to the parking disc by a cable and allows the park lock to be released manually. For
additional information, refer to 307-05B Automatic Transmission/Transaxle External Controls.
TRANSMISSION CONTROL MODULE
The TCM is an integral part of the Mechatronic valve block which is located at the bottom of the transmission, within the fluid pan. The TCM is the main controlling component of the transmission.
The TCM processes signals from the transmission speed and temperature sensors, ECM and other vehicle systems. From the received signal inputs and pre-programmed data, the module calculates the correct gear, torque converter clutch setting and
optimum pressure settings for gear shift and lock-up clutch control.

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the cause is not visually evident check for diagnostic trouble codes (DTCs) and refer to the DTC Index.

CAUTION: When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part
number 3548-1358-00.
NOTES:
If the control module/transmission is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty
Policy and Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior to the
installation of a new module/transmission.
Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional information
read by the manufacturer approved diagnostic system).
When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal
places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads
into account.
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.
If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.

6 Clockspring 7 Steering wheel audio switches 8 Upshift paddle switch 9 Downshift paddle switch 10 Instrument cluster 11 JaguarDrive selector
JAGUARDRIVE SELECTOR System Operation
Rotation of the JaguarDrive selector to any of the five positions is sensed by the TCM (transmission control module) via the
high speed CAN bus. A LIN bus connection is also provided, but is only used in the event of a CAN bus failure as a back-up. The TCM then reacts according to the selected position. The JaguarDrive selector is a magnetic system using Hall effect sensors to determine the position of the selector.
The S (sport) position selection allows the TCM to operate the transmission using the semi-automatic Jaguar sequential shift. Gear selections are sensed by the TCM when the driver operates the steering wheel paddle switches. Once the JaguarDrive selector position is confirmed, the TCM outputs appropriate information on the high speed CAN bus which is received by the instrument cluster to display the gear selection information in the message center.
Refer to: Information and Message Center (413-08 Information and Message Center, Description and Operation).
The paddles can also be used on a temporary basis when the JaguarDrive selector is in the D (drive) position to override the
automatic gear selection if required.
PARK INTERLOCK AND NEUTRAL LOCK
Neutral lock is a requirement for the JaguarDrive selector. The selector is always locked at ignition on when the engine is not
running, except after an engine stall when the selector is not in P (park) or N (neutral).
If, when driving with the JaguarDrive selector in S, D or R (reverse) at a speed of more than 5 km/h (3 mph), the driver selects
P or N:
Without the brake pedal pressed, the JaguarDrive selector will be immediately locked once the vehicle speed falls to
below 5 km/h (3 mph).
With the brake pedal pressed, the JaguarDrive selector will remain locked for as long as the brake pedal remains
pressed, regardless of vehicle speed.
The transmission will only engage park once the vehicle speed is less than 2 km/h (1 mph).
If the driver selects N and releases the brake pedal with a vehicle speed of less than 5 km/h (3 mph), the JaguarDrive selector
will be locked 2 seconds after N is selected. The selector will remain locked until the driver presses the brake pedal again.
To ensure that a driver request to change from a non-driving range (N for example) to a driving range (D for example), the park
interlock and neutral lock features are used in conjunction with the intermediate position.
If the transmission receives a range change request without the brake pedal pressed, the TCM initiates a soft lock function. The transmission will remain in park or neutral, depending on the starting position.
If a transmission position letter is flashing in the message center and the vehicle has no drive, the driver must:
Press the brake pedal.
Reselect N or P on the JaguarDrive selector.
Select the required driving range, ensuring that the brake pedal is pressed.
Rocking Function
The rocking function compliments the neutral lock function. For all changes from a non-driving range to a driving range, it is
necessary to press the brake pedal (to release either the park interlock or neutral lock).
In situations where the driver will require to change the gear selection from R to D, or from D to R, without brake pedal input
(car park maneuvering, 3 point turns or 'rocking' the vehicle from a slippery surface for example), the rocking function gives a 2
second lock delay when N is selected on the JaguarDrive selector and the brake pedal is not pressed.
Intermediate Position
If the JaguarDrive selector is rotated slowly from P to S and back to position P with the brake pedal pressed, the R or D
position display letter in the message center will flash and the transmission will remain in park or neutral depending on the
previous starting position of the selector.
If the brake pedal is released when R or D is flashing in the message center and the JaguarDrive selector is rotated to the R or
D position, the required range will not be selected and the transmission will remain in park or neutral, depending on the
previous starting position. This feature is known as soft lock.
If the driving range letter in the message center is flashing and the vehicle has no drive, the driver should depress the brake
pedal to reselect N or P, and then select the required driving range while the brake pedal remains pressed.
