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

DRIVE CLUTCHES



Item Description 1 Input shaft 2 Main pressure supply port 3 Piston 4 Cylinder – external plate carrier 5 Clutch plate assembly 6 Baffle plate 7 Diaphragm spring 8 Output shaft 9 Bearing 10 Dynamic pressure equalization chamber 11 Piston chamber 12 Lubrication channel There are three drive clutches and two brake clutches used in the ZF 6HP28 transmission. Each clutch comprises one or more
friction plates dependent on the output controlled. A typical clutch consists of a number of steel outer plates and inner plates
with friction material bonded to each face.

On 5.0L SC (supercharger) and 3.0L diesel models, the uprated transmission includes additional clutch plates to enable the
transmission to manage the additional power output from these engines.

The clutch plates are held apart mechanically by a diaphragm spring and hydraulically by dynamic pressure. The pressure is
derived from a lubrication channel which supplies fluid to the bearings etc. The fluid is passed via a drilling in the output shaft
into the chamber between the baffle plate and the piston. To prevent inadvertent clutch application due to pressure build up
produced by centrifugal force, the fluid in the dynamic pressure equalization chamber overcomes any pressure in the piston
chamber and holds the piston off the clutch plate assembly.

When clutch application is required, main pressure from the fluid pump is applied to the piston chamber from the supply port.
This main pressure overcomes the low pressure fluid present in the dynamic pressure equalization chamber. The piston moves,
against the pressure applied by the diaphragm spring, and compresses the clutch plate assembly. When the main pressure
falls, the diaphragm spring pushes the piston away from the clutch plate assembly, disengaging the clutch.

PLANETARY GEAR TRAINS

The planetary gear trains used on the ZF 6HP28 transmission comprise a single web planetary gear train and a double web
planetary gear train. These gear trains are known as Lepelletier type gear trains and together produce the six forward gears
and the one reverse gear.

Single Web Planetary Gear Train
The single web planetary gear train comprises:
Sunwheel
Three (naturally aspirated versions) or four (5.0L SC and 3.0L diesel versions) planetary gears Planetary gear carrier (spider)

Exhaust System - V8 5.0L Petrol/V8 S/C 5.0L Petrol - Exhaust System - Overview
Description and Operation

OVERVIEW

5.0L V8 NATURALLY ASPIRATED AND SUPERCHARGER - FROM 2010MY

The exhaust system fitted to models with the 5.0L V8 engines are fabricated from stainless steel. 5 separate assemblies make
up the complete system.

The front section comprises 2 separate assemblies (LH (left-hand) and RH (right-hand)) incorporating a catalytic converter for
each bank of cylinders. The rear section comprises 3 separate sections; a center section and two rear sections. The center
section assembly incorporates a rear silencer which is connected to a center resonator silencer. On supercharger models, the
center resonator is a one piece assembly with two inlet pipes from the center silencer and two outlet pipes to the rear
silencers. On naturally aspirated models, each outlet pipe from the center silencer connects into an individual center resonator.

The system is attached to the underside of the body with mounting rubbers which are located on steel hanger bars that are
welded to the system. The mounting rubbers locate on corresponding hangers which are welded or bolted to the underside of
the vehicle body.

Description and Operation



CATALYTIC CONVERTERS System Operation

In the catalytic converters, the exhaust gases are passed through honeycombed ceramic elements coated with a special
surface treatment called 'washcoat'. The washcoat increases the surface area of the ceramic elements by a factor of
approximately 7000. On top of the washcoat is a coating containing palladium and rhodium, which are the active constituents
for converting harmful emissions into inert by-products. The palladium and rhodium add oxygen to the carbon monoxide and
the hydrocarbons in the exhaust gases, to convert them into carbon dioxide and water respectively.

SEMI-ACTIVE MUFFLER VALVE (5.0L SUPERCHARGER VEHICLES ONLY)

The semi-active muffler valve is operated by the pressure in the exhaust system. At low engine speeds the valve head is
closed or partially closed to provide a more refined noise quality. At higher engine speeds the increased pressure within the
exhaust system opens the valve head to provide a more sporting noise. This is achieved by the valve, which once open, allows
the exhaust gasses to by-pass the baffle tubes and plates in the rear silencer.

Semi-Active Muffler Valve


NOTE: LH silencer shown, RH (right-hand) silencer similar


Item Description 1 Outer case 2 Overpipe 3 Valve cage 4 Semi-active muffler valve assembly A semi-active muffler valve is located in the rear of each rear silencer. The valve comprises a valve head, a valve shaft, a shaft
guide, a housing shell, a membrane and a spring. The valve head is connected to the membrane by the valve shaft which is
located within the shaft guide. The valve shaft is attached to the membrane with a pin. The membrane is located inside the
housing shell and is held in position by the spring.

The valve head is located in and seals against the over pipe. When the exhaust gas pressure increases and overcomes the
spring pressure, the valve head is lifted and the gasses by-pass the valve and are expelled though slots in the valve cage into
the rear chamber and into the outlet pipe.

When the semi-active muffler valve is closed the exhaust gasses are expelled from the inlet tube through the perforations. The
exhaust gasses then pass through perforations in the outlet pipe and are expelled from the silencer via the single outlet pipe
and 2 polished stainless steel finishers.

When the semi-active muffler valve is open, the exhaust gasses are released into the rear chamber. The exhaust gasses then
pass directly into the open end of the outlet pipe and are expelled from the silencer via the outlet pipe and the 2 polished
stainless steel finishers. With the valve open, the gasses reduce through the baffle plates and tube perforations giving the
exhaust note a more 'sporty' sound.
