WHEEL ALIGNMENT 2B-9
GENERAL DESCRIPTION AND SYSTEM OPERATION
FOUR WHEEL ALIGNMENT CASTER Caster is the tilting 91 the uppermost point of the steering axis either forward or backward from the vertical when viewed from the side of the vehicle. A backward tilt is positive, and a forward tilt is negative. Caster influencesdirectional control of the steering but does not affect
tire wear. Weak springs or overloading a vehicle will affect
caster. One wheel with more positive caster will pull
toward the center of the car. This condition will cause the car to move or lean toward the side with the least
amount of positive caster. Caster is measured in degrees. CAMBER Camber is the tilting of the top of the tire from the vertical when viewed from the front of the vehicle. When thetires tilt outward, the camber is positive. When the tires tilt inward, the camber is negative. The camber angle is measured in degrees from the vertical. Camber
influences both directional control and tire wear.
If the vehicle has too much positive camber, the outside
shoulder of the tire will wear. If the vehicle has too much
negative camber, the inside shoulder of the tire will wear.
The first responsibility of engineering is to design safesteering and suspension systems. Each componentmust be strong enough to withstand and absorb extremepunishment. Both the steering system and the front and the rear suspension must function geometrically with thebody mass. The steering and the suspension systems require that the front wheels self-return and that the tire rolling effortand the road friction be held to a negligible force in orderto allow the customer to direct the vehicle with the least effort and the most comfort. A complete wheel alignment check should include
measurements of the rear toe and camber. Four-wheel alignment assures that all four wheels will be running in precisely the same direction. When the vehicle is geometrically aligned, fuel economy and tire life are at their peak, and steering andperformance are maximized. TOE
Toe-in is the turning in of the tires, while toe-out is the turning out of the tires from the geometric centerline or thrust line. The toe ensures parallel rolling of the wheels. The toe serves to offset the small deflections of the wheel support system which occur when the vehicle is rollingforward. The specified toe angle is the setting whichachieves 0 degrees of toe when the vehicle is moving. Incorrect toe-in or toe-out will cause tire wear and
reduced fuel economy. As the individual steering andsuspension components wear from vehicle mileage,
additional toe will be needed to compensate for the wear. Always correct the toe dimension last.

5A-18 AUTOMATIC TRANSMISSIONINTRODUCTION
The BTR Automotive Model 74 Four Speed Automatic Transmission is an electronically controlled overdrive four
speed unit with a lock-up torque converter. The lock-up torque converter results in lower engine speeds at cruise and
eliminates unnecessary slippage. These features benefit the customer through improved fuel economy and noise
reduction. Refer to table 1.1 for details of power, torque and configuration.
Of primary significance is the transmission control unit (TCU) which is a microprocessor based control system. The
TCU utilizes throttle position, rate of throttle opening, engine speed, transmission output speed, transmission sump
temperature, gear selector position and mode selector inputs, and in some applications a ‘kickdown’ switch to control
all shift feel and shift schedule aspects.
The TCU drives a single proportional solenoid multiplexed to three regulator valves to control all shift feel aspects.
The output pressure of this solenoid is controlled as a function of transmission sump temperature to maintain consistent
shift feel throughout the operating range.
Shift scheduling is highly flexible, and several independent schedules are programmed depending on the vehicle.
Typically the ‘NORMAL’ schedule is used to maximise fuel economy and driveability, and a ‘POWER’ schedule is used
to maximise performance. ‘WINTER’ schedule is used to facilitate starting at second gear.
Figure 1.1 details the differences between conventional and electronic transmission control systems.

Reverse gear operation, with inhibitor engagement as a function of vehicle

Rear band applied only, with inhibited engagement as a function of vehicle
speed, engine speed and throttle position. The transmission output shaft is
locked. The inhibitor switch allows the engine to start.
Table 2.1 - Gear Selections DRIVING MODE SELECTOR
The driving mode selector consists of a mode selection switch and indicator light. The driving mode selector is
located on the centre console. See figure 2,1.
The schedules available to be selected vary with vehicle types. Typically the driver should have the option to select
between ‘NORMAL’ , ‘POWER’ or ‘WINTER’ modes.
When ‘NORMAL’ mode is selected upshifts will occur to maximise fuel economy and the indicator lights remain
extinguished. When ‘POWER’ mode is selected upshifts will occur to give maximum performance and the ‘POWER’
mode indicator light is swi tched on. When ‘WINTER’ mode is selected, starting at second gear is facilitated, the
‘WINTER’ mode indicator light is switched on and the ‘POWER’ mode indicator light is switched off.
Refer to the vehicle owner ’ s manual for specific modes for each vehicle type.

Figure 4.1 - Power Flow Diagram TORQUE CONVERTER
The torque converter (refer figure 4.2) consists of a turbine,
stator pump, impeller and a lock-up damper and piston
assembly. As in conventional torque converters, the impeller is
attached to the converter cover, the turbine is splined to the
input shaft and the stator is mounted on the pump housing via
a one way clutch (sprag).
The addition of the damper and piston assembly enables the
torque converter to ‘lock-up’ under favourable conditions. Lock-
up is only permitted to occur in third and fourth gears under
specified throttle and road speed conditions.
Lock-up is achieved by applying hydraulic pressure to the
damper and piston assembly which couples the turbine to the
converter cover, locking-up the converter and eliminating
unwanted slippage. Whenever lock-up occurs, improved fuel
consumption is achieved. Torsional damper springs are
provided in the damper and piston assembly to absorb anyengine torque fluctuations during lock-up. Figure 4.2 - Torque Converter Cross Section
