The epicyclic geartrain:
Provi des fi
ve forward gears and Reverse.
Has
h
ydraulically actuated, multi-disk clutches, to select the required gear ratios.
Feature

s clutch-to-clutch operation to permit
gear shifts for uninterrupted power flow.
The electro-hydraulic control unit:
Is lo c
ated in the lower part of
the unit, within the fluid pan.
Is controlled
by the TCM (transmissio
n control module), and the manual selector valve which is cable operated.
Re
gulates the flow of fluid to the ge
artrain clutches via three solenoid-operated valv es and the manual selector
valve.
Has fi ve pressure
regulators for controll
ing fluid pressures within the system.
Is con
nected to the TCM via a 16-way connector mounted on
the left-hand side of the transmission casing. Refer to
Connector Pins Identification, Section 307-01A.
The hydraulic system pump:
Is l o
cated at the front of the transmission casing.
Is dri
v
en from the impeller hub,
pressurising the fluid whenever the engine is running.
Supplie
s fluid under pressure to the torq
ue converter, geartrain, electro-hydr aulic control unit and the lubrication
circuit.
D r

does not require fluid changes, except where extreme driving conditions prevail.
Routine level checking is not required and a dipstick is not pr ovided. A level / filler plug is fitted for level checking and
replenishment, following service actions; see 303-01 General Procedures.

Paint
The inhalation of sprays, fumes, or dust during paint application or sanding processes should always be avoided. Ensure
that there is efficient ventilation / extrac tion at all times. Paint spraying should be confined as far as possible to spray
booths. Personnel with a history of asth ma should not be employed in any process involving the use of isocyanates.
Operators working in a spray booth where isocyanate material is present must use air-fed breathing equipment with air
supplied to the visor at the re commended pressure and filtered to remove oil, water, and fumes. Operators involved in
handling mixing or spraying should wear protective clothing including gloves and goggles, to avoid skin and eye contact.
Particle masks or canister type respir atosr should be worn when sanding.
Applied Heat
When welding, flame cutting, brazing etc, the operator shou ld use as appropriate, goggles, mask / fume extractor and
flameproof protective clothing. It is especially important when working with polyurethane compounds to use air-fed
breathing equipment. Appropriat e fire fighting equipment and personnel trai ned in its use must always be available.
Metal Repair
Appropriate eye and hand protection should be worn when sanding, drilling, cutting, chiselling, flatting or welding. Face
masks or air-fed visors should also be wo rn when sanding or flatting either body solder or fillers. On completion of a
soldering operation, swarf must be re moved from the work area and the operat or must wash his hands thoroughly.
GENERAL REPAIR NOTES
The following advice should be noted before any repair work is carried out.
Disconnect the vehicle battery gr ound lead (disconnect the alternator where electric welding is used) and take note of the
reconnection procedures as detailed in 86.15.15.
Where structural parts are straightened or renewed, a body alignment / straightening jig must be used. The application of
heat, especially excessive heat, reduces the strength of steels, where appropriate therefore, structural sections should be
straightened by cold processes.
Repairs may only be carried out successful ly, and any warranties protected, if genuine Jaguar replacement parts and Jaguar
approved materials are used.
The correct tools, procedures and facilities must always be us ed. The quality of the work must not be compromised by using
inappropriate methods or equipment.
All trim and electrical components in the locality of the repair must be removed or disconnected prior to panel removal /
replacement; this is especially important where hollow sectio ns may contain harnesses, tubes or foam, see section A4.3.5.
WARNING: DO NOT WORK IN THE VICINITY OF A LIVE AIR BAG, REMOVE IT COMPLETELY. READ WORKING
PRACTICES AIR BAG, SECTION 20. ANY SEAT BELT WHICH HAS BEEN WORN IN AN ACCIDENT MUST BE RENEWED.
CAUTION: Electric arc welding should not be used on Jaguar vehicles. The high voltages produced by this process will
cause irreparable damage to the electric al control and microprocessor systems.
The following welding and gas processes are the only ones recommended by Jaguar Cars Ltd.
Welding and Gas Processes
Resistance spot welding, MIG welding and all gas processes may only be carried out on bare, unpainted or unplated metal.
The flanges of panels to be welded toge ther, must be clean, corrosion free and tr eated as appropriate, with either weld-
through primer or inter-weld sealer. Only materials and processes specified in the 'Body Sealing and Preservation Manual'
should be used in the relevant application areas detailed in this section. Refer to 'Zinc Coated Panels' Section
