Section II. GENERAL DESCRIPTION AND DATA
1-4. Description
a. General Description.
(1) The Model TX 100-1 transmission (fig. 1-
1 and 1-2) is a full powershift, torque converter,
planetary gear transmission for military vehicles. It
is a compact unit which may be bolted to the
vehicle engine to form a unitary power pack, or
may be bolted to a transfer case in the power train.
(2) Power flows in a straight line from front to
rear of the transmission, passing in succession
through the torque converter, turbine shaft, and
transmission output shaft. Operations in reverse,
neutral, low, intermediate,
and high ranges are
provided.
(3) An automatic lockup clutch in the torque
converter gives direct drive from engine to range
gearing at higher engine speeds. With the lockup
clutch engaged during high-range operation, the
transmission input and output speeds are equal.
Power takeoff mountings are provided at both sides
of the transmission.
b. Definition of Locational and Directional
Tcrms.
(1)
Locational terms, used in describing the
transmission, are front, rear, right, and left. The
input, or torque converter end, is the front. The
output end is the rear. Right and left are toward the
viewer’s right and left when the transmission is
viewed from the rear.
NOTE
These directional terms may not agree with
those applicable to certain vehicles because
of different attitudes in which the trans-
mission may be installed.
(2) Rotational terms (clockwise and counter-
clockwise) will be established by references in the
text, or by the viewer’s position when using an
illustration.
c. Transmission Components.
The main com-
ponents of the transmission are identified in the
cross-section view (fig. 2-1). Chapter 2 covers in
detail the description and operation of all com-
ponents.
