If the turbine is rotating at a slower speed than the fluid from the impeller,
the fluid will be deflected by the turbine blades in the path 'A'. The fluid is directed at and deflected by the stator blades from
path 'B' to path 'C'. This ensures that the fluid is directed back to the pump in the optimum direction. In this condition the
sprag clutch is engaged and the force of the fluid on the stator blades assists the engine in rotating the impeller.

As the rotational speed of the engine and therefore the turbine increases, the direction of the fluid leaving the turbine changes
to path 'D'. The fluid is now directed from the turbine to the opposite side of the stator blades, rotating the stator in the
opposite direction. To prevent the stator from resisting the smooth flow of the fluid from the turbine, the sprag clutch releases,
allowing the stator to rotate freely on its shaft.

When the stator becomes inactive, the torque converter no longer multiplies the engine torque. When the torque converter
reaches this operational condition it ceases to multiply the engine torque and acts solely as a fluid coupling, with the impeller
and the turbine rotating at approximately the same speed.

The stator uses a sprag type, one way, freewheel clutch. When the stator is rotated in a clockwise direction the sprags twist
and are wedged between the inner and outer races. In this condition the sprags transfer the rotation of the outer race to the
inner race which rotates at the same speed. www.JagDocs.com

1 Sprags 2 Inner race 3 Outer race 4 Sprag and cage assembly 5 Sprag outer race 6 Sprag inner race 7 Retaining ring The free wheel clutch can perform three functions; hold the stator stationary, drive the stator and free wheel allowing the
stator to rotate without a drive output. The free wheel clutch used in the ZF 6HP28 transmission is of the sprag type and
comprises an inner and outer race and a sprag and cage assembly. The inner and outer races are pressed into their related
components with which they rotate. The sprag and cage assembly is located between the inner and outer races.

The sprags are located in a cage which is a spring which holds the sprags in the 'wedge' direction and maintains them in
contact with the inner and outer races.

Referring to the illustration, the sprags are designed so that the dimension 'B' is larger than the distance between the inner
and outer race bearing surfaces. When the outer race rotates in a clockwise direction, the sprags twist and the edges across
the dimension 'B' wedge between the races, providing a positive drive through each sprag to the inner race. The dimension 'A'
is smaller than the distance between the inner and outer race bearing surfaces. When the outer race rotates in an
anti-clockwise direction, the dimension 'A' is too small to allow the sprags to wedge between the races, allowing the outer
race to rotate freely.

On the illustration shown, when the outer race is rotated in a clockwise direction, the sprags twist and are 'wedged' between
the inner and outer races. The sprags then transfer the rotation of the outer race to the inner race, which rotates at the same
speed.

Lock-Up Clutch Mechanism

The TCC (torque converter clutch) is hydraulically controlled by an EPRS, which is controlled by the TCM. This allows the torque converter to have three states of operation as follows:
• Fully engaged
• Controlled slip variable engagement
• Fully disengaged.

The TCC is controlled by two hydraulic spool valves located in the valve block. These valves are actuated by pilot pressure supplied via a solenoid valve which is also located in the valve block. The solenoid valve is operated by PWM (pulse width One Way Free Wheel Clutch – Typical

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.

selector.

Rotation of the JaguarDrive selector allows the selection of P, R, N and D. By depressing the JaguarDrive selector and rotating
clockwise from the D position, S mode can be selected. The JaguarDrive selector is fully electronic rotary transmission selector
with no mechanical connection to the transmission.

The JaguarDrive selector rises from the JaguarDrive selector module once the engine is running. When the engine is stopped
with the JaguarDrive selector in any position other than N, it retracts into the JaguarDrive selector module again. If the
selector is in position N when the engine is stopped, it remains in the raised position for up to 10 minutes, for use in a drive
through car wash for example. After 10 minutes the selector automatically retracts into the JaguarDrive selector module. The
selector also retracts if P is selected within the 10 minute period.

If the JaguarDrive selector does not rise from the console when the engine is started, but electrical power is supplied to the
selector, the retracted selector can still be rotated to make selections. If electrical power to the JaguarDrive selector is lost,
the selector will not rise from the console when the engine is started and the retracted selector will not rotate.

The JaguarDrive selector contains an internal interlock solenoid to prevent the selector from being rotated when the engine is
not running.

The engine can be stopped with the JaguarDrive selector in any position. Once the engine is stopped the selector will
automatically reset to the P position and the transmission park lock will be engaged, except if the selector is moved to the N
position when the engine is stopped.

signal which is passed via the clockspring to the instrument cluster. The instrument cluster converts the signal into a high
speed CAN bus signal to the TCM.
Pulling the LH (left-hand) downshift - paddle provides down changes and pulling the RH (right-hand) upshift (+) paddle
provides up changes. The first operation of either paddle, after sport mode is selected, puts the transmission into permanent
manual Jaguar sequential shift mode. Rotation of the JaguarDrive selector back to the D position, returns the transmission to
conventional automatic operation.

Temporary operation of manual Jaguar sequential shift mode can also be operated with the JaguarDrive selector in the D
position. Operation of either the upshift or downshift paddles activates the manual mode operation. If the JaguarDrive selector
is in D, Jaguar sequential shift will cancel after a time period or can be cancelled by pressing and holding the + paddle for
approximately 2 seconds. PADDLE SWITCHES

1 Latch 2 Strap 3 Locking cylinder 4 Operating lever 5 Upper cable 6 Cable joint 7 Lower cable 8 Cable bracket 9 Park interlock lever If a vehicle requires recovery/transportation, the emergency park release mechanism is used to manually disengage the park
lock and engage the transmission in neutral.

The emergency park release mechanism consists of an operating lever that is connected to a park interlock lever on the
transmission by an upper and lower cable assembly.

The operating lever is installed in the floor console, under the trim panel between the drinks holder and the cubby box. The
park interlock lever is attached to the transmission selector shaft.

One end of the operating lever is attached to a base by a hinge pin. A locking cylinder is installed in the other end of the
operating lever, to secure the operating lever to the base. The operating lever is raised by pulling on a strap.
When operated, the emergency park release mechanism turns the transmission selector shaft.
To disengage the park lock:
Open the cubby box lid and the drinks holder lid.
Remove the trim panel from between the drinks holder and the cubby box.
Rotate the locking mechanism of the emergency park release lever 90 degrees counterclockwise.
Apply the footbrake, pull the operating lever upwards and ensure it locks in the vertical position.

Raising the operating lever causes the emergency park release cable to rotate the park interlock lever on the transmission,
which disengages the parking pawl and engages neutral. This allows the vehicle to freewheel.
To re-engage the park lock:

Hold the strap on the operating lever, release the latch and lower the operating lever to the horizontal position.
Lock the operating lever by turning the locking mechanism 90 degrees clockwise.
Install the trim panel.
Close the cubby box lid and the drinks holder lid. www.JagDocs.com
