GO to K2. K2: CHECK FOR BRAKE PEDAL BINDING 1 Disconnect the brake booster from the brake pedal. Check the brake pedal to ensure free operation. Is the brake pedal operating freely? Yes
Install a new brake booster as required. REFER to:
Brake Booster (206-07 Power Brake Actuation, Removal and Installation), Brake Booster - RHD (206-07, Removal and Installation).
Re-test the system for normal operation.
No
Repair or install new brake pedal. Re-test the system for normal operation. Component Tests

Brake Booster

1. Check all hoses and connections. All unused vacuum connectors should be capped. Hoses and their connections should
be correctly secured and in good condition with no holes and no collapsed areas. Inspect the valve on the brake booster
for damage.
2. Check the hydraulic brake system for leaks or low fluid.

3. With the automatic transmission in PARK, stop the engine and apply the parking brake. Pump the brake pedal several
times to exhaust all vacuum in the system. With the engine switched off and all vacuum in the system exhausted,
apply the brake pedal and hold it down. Start the engine. If the vacuum system is operating, the brake pedal will tend
to move downward under constant foot pressure. If no motion is felt, the vacuum booster system is not functioning.

4. Remove the vacuum hose from the brake booster. Manifold vacuum should be available at the brake booster end of the
hose with the engine at idle speed and the automatic transmission in PARK. Make sure that all unused vacuum outlets
are correctly capped, hose connectors are correctly secured and vacuum hoses are in good condition. When it is
established that manifold vacuum is available to the brake booster, connect the vacuum hose to the brake booster and
repeat Step 3. If no downward movement of the brake pedal is felt, install a new brake booster.

5. Operate the engine for a minimum of 10 seconds at a fast idle. Stop the engine and allow the vehicle to stand for 10
minutes. Then, apply the brake pedal with approximately 89 N (20lb) of force. The pedal feel (brake application) should
be the same as that noted with the engine running. If the brake pedal feels hard (no power assist), install a new valve
and then repeat the test. If the brake pedal still feels hard, install a new brake booster. If the brake pedal movement
feels spongy, bleed the brake system.
REFER to: Brake System Bleeding (206-00 Brake System - General Information, General Procedures). Brake Master Cylinder

Usually, the first and strongest indicator of anything wrong in the brake system is a feeling through the brake pedal. In
diagnosing the condition of the brake master cylinder, check pedal feel as evidence of a brake concern. Check for brake warning
lamp illumination and the brake fluid level in the brake master cylinder reservoir.
Normal Conditions
The following conditions are considered normal and are not indications that the brake master cylinder is in need of repair.

Modern brake systems are designed to produce a pedal effort that is not as hard as in the past. Complaints of light
pedal efforts should be compared to the pedal efforts of another vehicle of the same model and year.
The fluid level will fall with brake pad wear.

Abnormal Conditions

Changes in the brake pedal feel or brake pedal travel are indicators that something could be wrong in the brake system. The
diagnostic procedure and techniques use brake pedal feel, warning indicator illumination and low brake fluid level as indicators
to diagnosing brake system concerns. The following conditions are considered abnormal and indicate that the brake master
cylinder is in need of repair:

NOTE: Prior to carrying out any diagnosis, make sure the brake system warning indicator is functional.
Brake pedal goes down fast. This could be caused by an external or internal leak.
Brake pedal goes down slowly. This could be caused by an internal or external leak.
Brake pedal is low or feels spongy. This condition may be caused by no fluid in the brake master cylinder, reservoir cap
vent holes clogged or air in the hydraulic system.
Brake pedal effort is excessive. This may be caused by a bind or obstruction in the pedal/linkage, a faulty non-return
valve, booster or insufficient booster vacuum.
Rear brakes lock up during light pedal force. This may be caused by damaged brake pads, a partially applied parking
brake, a damaged ABS sensor or bearing failure.
Brake pedal effort erratic. This condition could be caused by the brake booster or incorrectly installed brake pads.
Brake warning indicator is on. This may be caused by low fluid level or float assembly damaged. www.JagDocs.com

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).

The TCM can be reprogrammed using a Jaguar approved diagnostic system using a flash code. The TCM processor has a 440 kb internal flash memory. Of this capacity, approximately 370 kb are used by the basic transmission program. The remainder,
approximately 70 kb is used to store vehicle-specific application data.

Engine Stall

If the vehicle stalls it will coast down in gear, with the transmission providing drive to the engine. A restart can be attempted
at this point and the engine may start and the driver can continue.

If the coast down speed reduces such that the speed of the engine is less than 600 rev/min, the transmission will go to
neutral, D illumination will flash in the instrument cluster. The driver needs to select neutral or park and then press the brake
pedal to restart the engine.

If the start/stop button is pressed when driving, the message ENGINE STOP BUTTON PRESSED is displayed in the message
center but there will be no change to the ignition state. If the driver requires to switch off the engine, the start/stop button
must be pressed for a second time. The engine will be stopped and will be back driven by the transmission as the vehicle
coasts down. When the engine speed is less than 600 rev/min the transmission engages neutral (flashing D illumination in the
instrument cluster). When vehicle speed is less than 2 km/h (1.2 mph) Park is engaged. The JaguarDrive selector automatically
rotates back to its lowered P position and the vehicle ignition is switched off.

The park engagement is prevented in a stall case as the ignition power is on and D was the last selected gear. The park
engagement speed at ignition off is from the least value of the wheel speeds (CAN signal) and transmission output speed (internal signal).


TRANSMISSION Component Description

The transmission comprises the main casing which houses all of the transmission components. The main casing also
incorporates an integral bell housing.

A fluid pan is attached to the lower face of the main casing and is secured with bolts. The fluid pan is sealed to the main
casing with a gasket. Removal of the fluid pan allows access to the Mechatronic valve block. The fluid pan has a magnet
located around the drain plug which collects any metallic particles present in the transmission fluid.

A fluid filter is located inside the fluid pan. If the transmission fluid becomes contaminated or after any service work, the fluid
pan with integral filter must be replaced.

The integral bell housing provides protection for the torque converter assembly and also provides the attachment for the
gearbox to the engine cylinder block. The torque converter is a non-serviceable assembly which also contains the lock-up clutch
mechanism. The torque converter drives a crescent type pump via drive tangs. The fluid pump is located in the main casing,
behind the torque converter.
The main casing contains the following major components:
Input shaft
Output shaft
Mechatronic valve block which contains the solenoids, speed sensors and the TCM Three rotating multiplate drive clutches
Two fixed multiplate brake clutches
A single planetary gear train and a double planetary gear train.

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.

Diagnosis and Testing

Principle of Operation

For a detailed description of the automatic transmission/transaxle, refer to the relevant Description and Operation section n
the workshop manual. REFER to: (307-01B Automatic Transmission/Transaxle - TDV6 3.0L Diesel /V8 5.0L Petrol/V8 S/C 5.0L
Petrol)

Transmission Description (Description and Operation), Transmission Description (Description and Operation), Transmission Description (Description and Operation).
Fluid Level and Condition Check


CAUTION: The vehicle should not be driven if the fluid level is low as internal failure can result.


NOTE: The transmission fluid temperature must not be allowed to exceed 50°C (122°F) whilst checking level. Should the
temperature rise above this figure, abort the check and allow the transmission fluid to cool to below 30°C (86°F).

This vehicle is not equipped with a fluid level indicator. An incorrect level may affect the transmission operation and could
result in transmission damage. To correctly check and add fluid to the transmission.
REFER to: Transmission Fluid Level Check (307-01B Automatic Transmission/Transaxle - TDV6 3.0L Diesel /V8 5.0L Petrol/V8 S/C 5.0L Petrol, General Procedures).

High Fluid Level

A fluid level that is too high may cause the fluid to become aerated due to the churning action of the rotating internal parts.
This will cause erratic control pressure, foaming, loss of fluid from the vent tube and possible transmission damage. If an
overfill condition is identified, with the engine at idle ensure the fluid temperature is within the specified range and allow the
excess fluid to drain until a small thread of fluid runs from the filler/level plug hole.

Low Fluid Level

A low fluid level could result in poor transmission engagement, slipping, or damage. This could also indicate a leak in one of
the transmission seals or gaskets.
REFER to: Transmission Fluid Level Check (307-01B Automatic Transmission/Transaxle - TDV6 3.0L Diesel /V8 5.0L Petrol/V8 S/C 5.0L Petrol, General Procedures).

Adding Fluid


CAUTION: The use of any other type of transmission fluid other than that specified can result in transmission damage.

If fluid needs to be added, add fluid in 0.50 liter increments through the fill hole Opening. Do not overfill the fluid. For fluid
type, refer to the General Specification chart in this section.
REFER to: Specifications (307-01B Automatic Transmission/Transaxle - TDV6 3.0L Diesel /V8 5.0L Petrol/V8 S/C 5.0L Petrol, Specifications).

Fluid Condition Check

1. Check the fluid level.
REFER to: Transmission Fluid Level Check (307-01B Automatic Transmission/Transaxle - TDV6 3.0L Diesel /V8 5.0L Petrol/V8 S/C 5.0L Petrol, General Procedures).
2. Observe the color and the odor of the fluid. The color under normal circumstances should be Honey.

3. Allow the fluid to drip onto a facial tissue and examine the stain.
4. If evidence of solid material is found, the transmission fluid pan should be removed for further inspection.

NOTE: In the event of a transmission unit replacement for internal failure, the oil cooler and pipes must also be replaced.

Inspection and Verification

1. Verify the customer concern.

2. Visually inspect for obvious signs of damage and system integrity.
