Automatic Transmission (AJ16)
Both types of automatic transmission comprise a hydrodynamic torque converter driving an epicyclic gear train which
provides four forward ratios and reverse. Gearshift selection is made by a hydraulic (or electronichydraulic) trans- mission control unit. Six gearshift positions are provided:
Position
'P' (Park) -the driven wheels are mechanically locked at the transmission.
Position
'R' (Reverse) - reverse gear selected.
Position
'N' (Neutral) - engine disconnected from drive-line and wheels.
Position 'D' (Drive)
- all four speed ranges are selected automatically with lock-up available in top gear only.
Position
'3' - automatic selection of the lowest three speed ranges only.
Position '2'
- automatic selection of the lowest two speed ranges only; the transmission is prevented from shift- ing up to the third and top speed ranges.
Immediate selection of a lower ratio is also available, within mapped limits, by 'kick
-down' (pressing the accelerator
pedal down beyond the normal full throttle position) for example when overtaking.
A brake pedal/gearshift interlock is incorporated in the shift lever mechanism. Theshift lever may only be movedfrom
the 'P' (Park) position if the ignition key switch is in position 'll', and the foot brake is applied. The ignition key cannot
be removed from the ignition switch unless the shift lever is in the 'P' (Park) position. Once the ignition key has been
removed, the shift lever is locked in the Park position. The gearshift interlock may be over-ridden manually in the event
of an electrical failure or when it is required to move the vehicle manually for access, ie for removal of the propeller
shaft.
8.1.1.1
Gearshift selection causes the appropriate gear to be selected through a cable operated shift lever on the side of the
Gear Selection (ZF 4HP 22)
transmission unit. When a gea; is selected, the shift points are determined by accelerator pedal position through a
throttle cable connection and by pressures equivalent to road speed derived from a centrifugal governor on the output
shaft.
Gearshift speed and quality are controlled by the hydraulic control unit located in the lower part of the transmission
housing. The control unit contains selector valve, control pistons and pressure valves.
The hydraulic control unit can be overridden by 'kickdown'. This is actuated by the final travel of the accelerator pedal
and causes the next lower gear to be selected.
8.1.1.2
Gearshift selection causes the appropriate gear to be selected through a cable operated shift lever on the side of the
transmission unit; the shift lever also operates a rotary switch attached to the side of the transmission unit. When a
gear is selected, the rotary switch provides an output or combination of outputs to the TCM, which continuously moni
- tors the gear selected in addition to output shaft speed and transmission oil temperature. Information from the Engine
Control Module (ECM) representing engine speed, load and throttle position is also fed to the TCM to enable the most
suitable gear to be selected.
Gear selection and gearshift speeds are controlled by the manually operated selector valve, a solenoid operated pres
- sure regulator and three solenoid valves. On receipt of signalsfrom the TCM, the three solenoid valves MVI, MV2 and
MV3, in various combinations with the safety valve, determine the appropriate gear range. The TCM, on receipt of
information of engine state and road speed, determines the shift speed.
The Performance Mode switch, located on the shift lever surround, provides two alternative shift speed patterns:
1. 'Normal (Economy) Mode' - designed for everyday use.
2. 'Sport Mode'
- gear shift takes place at higher road speeds to enhance performance.
The 'kick
-down' switch, located beneath the accelerator pedal, is actuated by the final travel of the pedal and signals
to the TCM that the next lower gear is to be selected.

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.
