Syringe 1. Raise the vehicle for access.

2. NOTE: This procedure will not re move residual fluid from the
torque converter.
Drain the transmission fluid.
2. WARNING: TRANSMISSION FLUID MAY CAUSE
SEVERE BURNS, ENSURE THAT ALL SAFETY PROCEDURES
ARE OBSERVED AND THAT THE RECEPTACLE FOR WASTE
HAS SUFFICIENT CAPACITY.
Carefully remove the drain plug and drain the
transmission fluid.

3. Refit the drain plug and tighten to the specified torque figure.
Use a new O-ring.

1. Remove the fluid level / filler plug.
2. Using a syringe dedicated to tran smission fluid only (not used
for any other type of oil or fluids ), inject transmission fluid until

Transmission/Transaxle Cooling - 4.0L NA V8 - AJ27/3.2L NA V8 - AJ26 -
Transmission Cooling
Description and Operation
The transmission fluid cooling system maintains fluid temperature within specified limits.

Parts List
Component Descriptions
The transmission fluid pipes:
Transfer fluid from the transmission to the cooler under the action of the hydraulic system pump. Return the cooled fluid from th e cooler to the transmission.
The transmission fluid cooler:
Is a plate type made from aluminum. Is mounted in the engi ne cooling radiator right-hand end tank.
Overheating Protection
If the engine coolant or transm ission fluid temperatures exceed their predefined limits, th e transmission control module locks
the torque converter clutch. By reducing slip, this minimises th e amount of heat transferred to the engine cooling system from
the transmission fluid.

WARNING: NEVER USE A CFC 12 ANALYZ
ER OR NAKED FLAME TYPE.
Leak tests should be carried out with a UV spot lamp or an electronic analyzer which is dedicated to HFC 134A refrigerant.
Handling Lubricati
ng Oil
Av
oid breathing lubricant mist; it can cau
s
e irritation to the respiratory system.
Always use fresh oil from a sealed containe r and do not leave oil exposed to the atmosphere for any reason other than to fill
or empty a system. PAG oil is very hygr oscopic (absorbs water) and will rapidly become contaminated by atmospheric
moisture.

PAG oil is NOT compatible with previously used mineral based oi ls and must NEVER be mixed. Do not re-use oil when it has
been separated from refrigerant, following a re covery cycle. Dispose of used oil safely.
System Maintenance
Plug pipes an
d units immediatel
y after disconnection an d do not remove the plugs until immediately before making the
connection. Do not leave the system open to atmosphere.
The receiver drier must be renewed if the compressor has failed or if it is susp ected that debris may be present in the
system.
It is not always necessary to renew th e receiver drier if the correct procedur es have been followed. However, if a
component or part of the system is left dismantled for more than five minutes, it may be advisable to renew the receiver
drier. This guidance is based on UK average humidity levels; lo cations with lower humidity levels will be less critical to
moisture contamination. It must be stressed however th at there is not a safe period for work to be carried out in.
Do not use any replacement parts su pplied without transit plugs and seals - return them to the supplier.
Diagnostic equipment for pres sure, mass and volume should be calibrated regularly and certified by a third party
organization.
Use extreme care when handling and securi ng aluminum fittings; always use a backing spanner and take special care when
handling the evaporator.
Use only the correct or re commended tools for the job and apply the manufacturer's torque specifications.

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
