OPERATORS INTERFACES
There are three operator interfaces as the following;
•
Gear Shift Control Lever
•
Driving Mode Selector
•
Indicator Light
Gear Shift Control lever
The transmission uses a conventional shift control lever.
The gear shift control lever can be moved from one
position to another within the staggered configuration
of the shift control lever gate to positively indicate the
gear selection.
DESCRIPTION AND OPERATION
BTRA M74 4WD AUTOMATIC
TRANSMISSION
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.
Of primary significance is the Transmission Control Mo-
dule (TCM) which is a microprocessor based control
system.
The TCM utilizes throttle position, rate of throttle open-
ing, engine speed, vehicle speed, transmission fluid
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 TCM drives a single proportional solenoid multi-
plexed to three regulator valves to control all shift feel
aspects. The output pressure of this solenoid is con-
trolled as a function of transmission fluid temperature
to maintain consistent shift feel throughout the
operating range.
Shift scheduling is highly flexible, and several indepen-
dent schedules are programmed depending on the ve-
hicle.
Typically the NORMAL schedule is used to maximize
fuel economy and driveability, and a POWER schedule
is used to maximize performance. WINTER schedule
is used to facilitate starting in second gear.

•
P - Park position prevents the vehicle from rolling
either forward or backward by locking the
transmission output shaft. The inhibitor switch
allows the engine to be started. For safety reasons,
the parking should be used in addition to the park
position. Do not select the Park position until the
vehicle comes to a complete stop because it
mechanically locks the output shaft.
•
R - Reverse allows the vehicle to be operated in a
rearward direction. The inhibitor switch enables re-
verse lamp operation.
•
N - Neutral allows the engine to be started and oper-
ated while driving the vehicle. The inhibitor switch
