Figure 1-1. 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. 1-5.
