TRANSAXLE TA6300 1 1. GENERAL INFORMATION The transmission TA6300 provides six forward speeds and one reverse speed by means of six synchronizers and input shaft, lay shaft and reverse idler shaft and differential. All forward gears are in constant mesh engaged through synchronizers and reverse gear uses a sliding idler gear arrangement. 1st/2nd gear synchronizers are mounted on lay shaft and 3rd/4th/5th/6th gear synchronizers mounted on input shaft. The lay shaft turns the final drive gear and differential assembly, thereby turning the front drive shafts which are attached to the front wheels. Movement of gear shift lever / knob is transmitted through gear shift cables and shift /select levers on transmission to the selector shifting finger. This is further transmitted through shifter dogs and shifter forks to the shifter sleeves and synchronizers. Interlock piece is provided to prevent double engagement of gears. Central detent and shaft detents are provided for distinct position of gears about neutral position. MAJOR HIGHLIGHTS OF TA6300: 1. The internal and external gear shifting mechanism and arrangement suitable for cable shift. 2. Twin cone brass synchronizers for 1st/2nd gears and single cone carbon lined synchronizers for 3rd/4th/5th/6th gears. Benefits are shift smoothness, less shift efforts and enhanced life of synchro cones. 3. Single unit called 'Assembly Top cover' which operates selection and shifting of gears 4. Features of top cover are: The shifting components can be serviced by removing the top cover alone. The selector shifter shaft seal is located on top. A well optimized cam profile on shift finger, gives good shift feel and precision. 5. The reverse light switch kept on the top side of transmission, to reduce failures of oil dipped switch.
