0 2.1 JACKING AND LIFTING
2.1.1. Safety Precautions
The following safety precautions must be observed when
raising the vehicle to perform service operations:
0 Whenever possible use a ramp or a pit in preference
to a jack, when working beneath a vehicle.
0 Never rely on a jack to support a vehicle; use axle
stands or blocks under the vehicle jacking points to
provide rigid support.
0 When working beneath a vehicle, chock the wheels in
addition to applying the handbrake.
0 Ensure that the vehicle is standing on firm, level
ground before using the jack
0 Check that any lifting equipment used has adequate
capacity for the load being lifted and is in full working
order.
2.1.2 Jacking Points
The jack provided in the vehicle toolkit engages with jacking
points situated below the body side members, in front of the
rear wheels (Fig.
1) and behind the front wheels (Fig. 2).

2.1.3 WheeLFree L i#t
Use of a wheel-free lift is recommended for maintenance operations. Support the vehicle using lifting pads at the four
jacking points (Fig. 3).

2.2.4 Transporting
If thevehicle is being transported on a trailer or flatbed transporter (Fig. I), the handbrake must be applied, the wheels
chocked and if fitted with an automatic transmission, the gear selector lever moved to neutral, 'N' (see Gear-shift
Interlock).

Automatic Transmission (V12 & AJl6 Supercharged) Pomrtrain
8.2.1 GENERAL DESCRIPTION
This section provides information relating to the Powertrain 4L80-E transmissions fitted to the 4,O liter supercharged
engine (4,OL SC) and to the 6,O liter engine (6,OL).
The Powertrain 4L80-E is a four-speed, high torque capacity, electronically controlled automatic transmission, which
comprises a torque converter with lock-up direct drive clutch and three planetary gear sets. Five multiple diskclutches,
one intermediate sprag clutch assembly, two roller clutch assemblies and two band assemblies provide the drive el- ements necessary for correct sequential gear engagement and operation.
The torque converter containing
a pump, a turbine (rotor), a stator assembly, and a clutch pressure disksplined to the
turbine, acts as a fluid coupling for smooth torque transmission from the engine. The converter also supplies addi- tional torque multiplication when necessary, and the torque converter clutch (TCC) pressure disk provides a mechan- ical direct drive or 'lock-up' above a certain speed in top gear for greater fuel economy.
Gearshift operations are controlled from the Transmission Control Module (TCM), which governs the electronically
controlled valve body situated within the transmission.
Three planetary gear sets provide reverse and the four forward ratios, the changing of which is fully automatic in rela
- tion to load, vehicle speed and throttle opening. The Transmission Control Module receives and integrates various ve- hicle sensor input signals, and transmits operating signals to the solenoids located in the control valve assembly.
These solenoids govern the transmission operating pressures, up-shift and down-shift gear selection patterns and
also the torque converter clutch operation by pulse width modulated control.
8.2.1.1 Gear Ranges
Selectable gear positions are: P - Park, R - Reverse, N - Neutral, D - Drive, 3, 2.
P - Park position of the shift lever provides a mechanical locking of the output shaft of the transmission, and as such,
must only be engaged when the the vehicle is stationary. In addition, and for
extra safety, the handbrake should also
be applied. It is necessary to have the ignition ON and the footbrake applied to move the shift lever from the Park
position. For ignition key removal the shift lever must be in the Park position. The engine can be started in the Park
position.
R - Reverse enables the vehicle to be operated in a rearwards direction. The engine cannot be started in the Reverse
position.
N
-Neutral position enables the engine to be started and operated without driving the vehicle. It also allows the vehicle
to be moved manually for access, ie for removal of the propeller shaft.
D
-Drive position allows the automatic selection of all four forward gear ratios during normal driving conditions for
maximum efficiency and fuel economy. On acceleration, down-shifts are obtained by depressing the accelerator pedal
or by manual selection. The engine cannot be started in this position.
3
- Manual third position allows automatic operation of the three lower gear ratios but inhibits selection of the fourth
ratio. This position is used for towing a trailer or negotiating hilly terrain when greater engine braking control is re- quired. The engine cannot be started in this position.
2 - Manual second position allows automatic operation of the two lower gear ratios but inhibits selection of the third
and fourth ratios. This position is used for heavy traffic congestion or negotiating hilly terrain when even greater en
- gine braking control is required than is provided by manual third. This ratio may be selected at any vehicle speed - even if the transmission is in third or fourth ratio, the transmission will immediately down-shift to second gear pro- vided the vehicle speed is below 137 km / h (85 mile / h). The engine cannot be started in this position.
N.g!b: With the Performance Mode switch in the NORMAL position, the vehicle will pull away in second gear. How- ever, if more than 75 per cent of throttle is applied when the vehicle speed is between zero and 13 km/ h (8 mile / h), then first gear will be selected. From 13 to 61 km/ h (8 to 38 mile/ h) first gear is obtainable by 'kick-down'.
In 'sport' mode thevehicle pulls away in first gear and the transmission operatesfully in all four forward gears.

1 Parking Brake Layout
All vehicles are fitted with identical parking brake systems.
When the parking brake lever
is operated, the cable system applies equal force to both RH and LH brakeshoe expander
assemblies. The brake shoes expand and press against the hub assembly, locking the rear wheels.
The handbrake lever, ratchet assembly and warning
light switch (item 1) are mounted on the transmission tunnel by means of threeflanged screws a blanking plate and gasket. The front cable (item 2) is connected to the relay lever (item 3) which is mounted on the driveshaft securing bracket (item 4). The relay lever operates the intermediate cable (item 5) which incorporates an adjusting screw to allow cable tension to be adjusted. The intermediate cable operates the
equalizer which ensures that equal force is applied to RH and LH parking brakesvia rearcable RH (item 8) and rear cable
LH (item 9). The rear cables are adjustable to allow cable tension to be adjusted.
The park brake switch (item 10) latches when the lever
is operated and lights the parking brake warning light (item 11 mounted in the instrument panel.
X300 VSM Issue 1 August 1994

Brakes
Parking Brake Adjusfmenf
Cable slack must be removed by adjustment of the intermediate cable length. The handbrake should be fully on be-
tween three and five clicks.
Parking Brake Shoe Assembly
The parking brakes are of the duo-sewo type. The expander
assembly (6 Fig. 1) is mounted on the backplate mounting
lug. The brake shoes locate on the expander assembly and
the adjuster
(1 Fig. I).These are held in position by the upper
and lower return springs (4 and 5 Fig. 1) and the hold down
springs (2 Fig. 1). The adjuster allows manual adjustment of
the brake shoes.
To remove the brake shoe assemblies the handbrake must
be released and the adjuster slackened.
The use of
a spring removal tool is recommended when re- moving the brake shoes. Strong pliers may be used, but
there is a risk of both personal injury and loss of compo- nents, should the pliers slip.
lnspedion and Cleaning
Clean and examine all components for wear or damage, re- newing parts as necessary. Fig.
1
When
reassembling the expander assembly, liberally grease the components using a proprietary mechanical brake
grease. Lightly grease the threads of the adjuster.
CAUTION: Do not get grease onto the lining material. Light surfacecontamination can be removed with emery cloth,
but heavy penetration of grease or fluid will render the material unsuitable for further use and the linings
must be renewed.
Re-assembly
When reassembling the brake shoes, lightly grease the shoe tips and back plate contact area. The brake shoes and
the expander assembly should befitted to the backplate with the lower return spring in position. When the brake shoes
are located, the adjuster, upper return spring and hold down springs should then be fitted. The brake shoes should
be adjusted
so that the brake rotorhub can just be fitted. Final adjustment should allow the brake rotor/hub to rotate
without excessive drag. Light running contact is permissible.
