Automatic Transmission/Transaxle - TDV6 3.0L Diesel /V8 5.0L Petrol/V8 S/C 5.0L Petrol - Transmission Description - Overview
Description and Operation

OVERVIEW

The ZF 6HP28 transmission is an electronically controlled, hydraulically operated, six speed automatic unit. The hydraulic and
electronic control elements of the transmission, including the TCM (transmission control module), are incorporated in a single
unit located inside the transmission and is known as 'Mechatronic'.

5.1 L SC (supercharger) and 3.0L diesel models use an uprated derivative of the ZF 6HP28 transmission used in the 5.0L
naturally aspirated models.
The ZF 6HP28 transmission has the following features:
Designed to be maintenance free
Transmission fluid is 'fill for life'
The torque converter features a controlled slip feature with electronically regulated control of lock-up, creating a smooth
transition to the fully locked condition
Shift programs controlled by the TCM Electronic park lock, controlled by the TCM, with a mechanical emergency release ASIS (adaptive shift strategy), to provide continuous adaptation of shift changes to suit the driving style of the driver,
which can vary from sporting to economical.
Connected to the ECM (engine control module) via the high speed CAN (controller area network) bus for communications
Default mode if major faults occur
Diagnostics available from the TCM via the high speed CAN bus.
The transmission selections are made using the rotary JaguarDrive selector in the floor console and two paddle switches on the
steering wheel. For additional information, refer to 307-05B Automatic Transmission/Transaxle External Controls - 5.0L/3.0L
Diesel).

POWER FLOWS System Operation

Operation of the transmission is controlled by the TCM (transmission control module), which electrically activates various
solenoids to control the transmission gear selection. The sequence of solenoid activation is based on programmed information
in the TCM memory and physical transmission operating conditions such as vehicle speed, throttle position, engine load and JaguarDrive selector position.

1 Transmission selected gear status 2 MIL (malfunction indicator lamp) 3 Message center The instrument cluster is connected to the TCM via the high speed CAN bus. Transmission status is transmitted by the TCM and displayed to the driver in one of two displays in the instrument cluster. For additional information, refer to 413-01
Instrument Cluster.

Malfunction Indicator Lamp

The MIL (malfunction indicator lamp) is located in the tachometer in the instrument cluster. Transmission related faults which
may affect the vehicle emissions output will illuminate the MIL.
The MIL is illuminated by the ECM (engine control module) on receipt of a relevant fault message from the TCM on the high speed CAN. The nature of the fault can be diagnosed using a Jaguar approved diagnostic system which reads the fault codes stored in the TCM memory.
Transmission Status Display

The transmission status display is located in a LCD (liquid crystal display) at the top of the instrument cluster, between the
speedometer and the tachometer. The LCD shows the JaguarDrive selector position or the selected gear when in manual 'Jaguar Sequential Shift' mode.
The following table shows the displays and their descriptions.

Symbol Description P Park selected R Reverse selected N Neutral selected D Drive selected S Sport mode selected 1 1st gear selected (manual Jaguar sequential shift mode) 2 2nd gear selected (manual Jaguar sequential shift mode) 3 3rd gear selected (manual Jaguar sequential shift mode) 4 4th gear selected (manual Jaguar sequential shift mode) 5 5th gear selected (manual Jaguar sequential shift mode) 6 6th gear selected (manual Jaguar sequential shift mode) The message center is located in the lower center of the instrument cluster. The message center is a LCD to relay vehicle status and operating information to the driver and can display messages relating to a number of the vehicle systems. If a
transmission fault occurs, the message center will display the message 'GEARBOX FAULT'.

TRANSMISSION CONTROL MODULE

The TCM outputs signals to control the shift control solenoid valve and the EPRS (electronic pressure regulating solenoid) to control the hydraulic operation of the transmission.

The TCM processes signals from the transmission speed and temperature sensors, the 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.

The ECM supplies the engine management data over the high speed CAN bus. The TCM requires engine data to efficiently control the transmission operation, for example; flywheel torque, engine speed, accelerator pedal angle, engine temperature.
The steering angle sensor and the ABS (anti-lock brake system) module also supply data to the TCM on the high speed CAN bus. The TCM uses data from these systems to suspend gear changes when the vehicle is cornering and/or the ABS module is controlling braking or traction control.

Using the signal inputs and the memorized data, the TCM control program computes the correct gear and torque converter lock-up clutch setting and the optimum pressure settings for gear shift and lock-up clutch control. Special output-side modules
(power output stages, current regulator circuits), allow the TCM to control the solenoid valves and pressure regulators and consequently precisely control the hydraulics of the automatic transmission. In addition, the amount and duration of engine
interventions are supplied to the engine management by way of the CAN bus.
The transmission has a fully electronic JaguarDrive selector with no Bowden cable connection to the transmission. The
transmission selections are made using a rotary JaguarDrive selector which rises from the floor console once the engine is
running. Rotation of the JaguarDrive selector to any of the five positions is sensed by the TCM via the high speed CAN bus. The TCM then reacts according to the selected position. 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.
If the JaguarDrive selector is in 'D', 'Jaguar Sequential Shift' is temporary and will cancel after a time period or can be cancelled
by pressing and holding the + paddle for approximately 2 seconds.

If the JaguarDrive selector is in 'S', 'Jaguar Sequential Shift' is permanent and can only be cancelled by pressing and holding
the + paddle for approximately 2 seconds or by moving the JaguarDrive selector to the 'D' position.

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.

Speed Control - V8 5.0L Petrol/V8 S/C 5.0L Petrol - Speed Control - Overview
Description and Operation

OVERVIEW

Speed Control

The speed control system is integrated with the engine management system and uses fueling intervention to automatically
maintain a set vehicle speed. Once engaged, the system can also be used to accelerate the vehicle without using the
accelerator pedal.
The speed control system comprises the following components:

On/Off/Suspend switch
'+' and '-' (set/accelerate and decelerate) steering wheel switches
Resume switch
Clock spring
Speed control warning indicator.
Adaptive Speed Control

The adaptive speed control system uses a forward looking radar sensor to scan the road ahead, looking for objects that are
moving at a different rate to itself. When a target is identified the adaptive speed control system will monitor the time gap
between it and the target vehicle. When that gap falls below a set driver selected level the adaptive speed control system will
intervene slowing the vehicle by backing off the throttle and/ or applying the brakes, until the correct gap is attained.
The adaptive speed control system comprises the following components:
Adaptive speed control sensor
Adaptive speed control module
Steering wheel control switches
ECM (engine control module)
Electric throttle actuator
ABS (anti-lock brake system) module and pump
Adaptive speed control warning indicator (in the instrument cluster).

6 Clockspring 7 APP (accelerator pedal position) sensor 8 Electric throttle actuator 9 Brake lamp/brake test switch 10 Adaptive speed control radar sensor 11 Diagnostic socket 12 Instrument cluster 13 TCM (transmission control module) 14 Adaptive speed control module


SPEED CONTROL System Operation

The speed control system uses inputs from the brake lamp/brake test switch, the APP sensor, the ECM and the ABS module.
Speed control is operated by the driver using only the steering wheel switches. When speed control is active, the ECM regulates the PWM (pulse width modulation) signals to the fuel injectors to adjust the fuel supply as required to maintain the
set speed.

During speed control operation, the ECM controls vehicle speed by adjusting fuel injection duration and timing. When the accelerator pedal is pressed with speed control active, the ECM outputs a calculated throttle angle signal in place of the actual throttle angle signals produced by the APP sensor. The calculated throttle angle is derived from fuel demand.
The minimum set speed for speed control is 18 mph (30 (km/h). Speed control is automatically suspended if the following
conditions apply:

Vehicle speed falls below 18 mph (30 km/h)
The brake pedal is pressed
The cancel button is pressed
Neutral, park or reverse gear is selected
The difference between actual speed and the set speed is too great
If the engine speed becomes near to the red line (maximum engine speed)
If the accelerator pedal is used to accelerate beyond the set speed for too long.

ADAPTIVE SPEED CONTROL
The adaptive speed control system comprises the following components:
Adaptive speed control sensor
Adaptive speed control module
Steering wheel control switches
ECM
Electric throttle actuator
ABS module and pump Adaptive speed control warning indicator.

The adaptive speed control system uses a forward looking radar sensor to scan the road ahead, looking for objects that are
moving at a different rate to itself. When a target is identified the adaptive speed control system will monitor the time gap
between it and the target vehicle. When that gap falls below a set driver selected level the adaptive speed control system will
intervene slowing the vehicle by backing off the throttle and/ or applying the brakes, until the correct gap is attained. The
driver can chose between four gap settings, 1, 1.4, 1.8 and 2.2 seconds.
The system will detect but not react to the following:
Vehicles in the oncoming lane
Stationary vehicles
Pedestrians
Vehicles not in the same lane.

Adaptive speed control is active when the vehicle is moving. Adaptive Speed Control only functions when a set speed is
entered in normal speed control mode. The adaptive speed control system only intervenes with the set speed when it detects
a target vehicle, and then only if the minimum time gap is breached.

It is important to note that the system is intended for use in limited driving situations, does not remove control and
responsibility from the driver, and at all times can be quickly overridden. The adaptive speed control system is not a collision
warning system and will not react to stationary objects. The system does not operate below a minimum speed of
approximately 30 km/h (20 mph) since it is unsuitable for use in cities or congested traffic. The system is best suited to main
roads/ highways with gradual bends.
The ECM, throttle body and throttle control are unchanged from those used for non adaptive speed control variants.
The adaptive speed control system is based on the use of a front mounted radar sensor. The sensor transmits a 1.5° wide
beam forward of the vehicle and detects the returning signals reflected off other vehicles and objects ahead.
The 1.5° wide radar beam is mechanically scanned at a rate of 10 sweeps/second across a total arc of 15° centered on the
