OBJECTIVES

After studying Chapter 10, the reader should be able to:

  • Describe some of the transmissions used in domestic vehicles.
  • Describe some of the transmissions used in the more popular import vehicles.
  • Explain the operation of a particular transmission.
  • Identify which transmission is used in a particular vehicle.
  • Identify a particular transmission.
introduction
INTRODUCTION
  • In the following sections, we will briefly describe the more common transmission and transaxles.
  • They will be described by manufacturer and cross-referenced by the gear train types described in Chapter 5.
  • A particular transmission design may have many small differences.
  • In any single year, there may be many versions of the same transmission depending on the application.
introduction1

FIGURE 10-1 When a vehicle is driving straight, the differential gears rotate as a unit; equal load keeps the pinion gears stationary on the mate shaft (a). An unequal load causes the pinion gears to rotate on the mate shaft so one axle can turn faster than the other (b). (Courtesy of Chrysler Corporation)

INTRODUCTION
  • Transaxles
    • A transaxle is a combination of a transmission, either standard or automatic, and a final drive assembly.
introduction2
INTRODUCTION
  • There are essentially four types of final drive and differential combinations used in transaxles:
    • The first type uses helical gears and an intermediate/idler gear or shaft to transfer power from the transmission planetary gear assembly to the differential case
    • The second type uses a planetary gearset mounted to the output of the transmission gearset for the final drive reduction gears
    • The third type uses a planetary gear final drive that is driven by a chain and sprockets from the transmission section
    • Some FWD vehicles use an engine mounted lengthwise in the vehicle so the crankshaft and the transaxle shafts run longitudinal (fore and aft) instead of transverse or lateral (side to side) relative to the vehicle.
introduction3

FIGURE 10-2 The 41TE transaxle uses a set of helical final drive gears (a) to transfer power from the transfer shaft to the differential and drive shafts. A set of helical transfer gears (b) is used to transfer power from the transmission gears to the transfer shaft. (Courtesy of Chrysler Corporation)

INTRODUCTION
introduction6

FIGURE 10-5 The overall gear ratio in a transaxle is a product of multiplying the transmission gear ratio by the final drive ratio. This should be multiplied by any transfer gear/chain ratio.

INTRODUCTION
  • New-Generation Transmissions and Transaxles
    • Vehicle manufacturers are working to improve vehicle efficiency, performance, and fuel mileage.
    • Transmissions and transaxles are being introduced that are smaller, lighter, and have additional gear ranges.

  • Torqueflites are three-speed, Simpson gear train transmissions of two basic sizes.
  • The A-904 was introduced as a Torqueflite 6 (TF6) in 1960 for use with 6-cylinder engines.
  • The A-727 was introduced in 1962 for use with 8-cylinder engines.
  • The A-727 is called the Torqueflite 8 (TF8).

saturn transaxle
SATURN TRANSAXLE
  • Saturn began as an independent division of General Motors, and these vehicles use a FWD transverse engine and transaxle of their own design.
  • This transaxle is called the TAAT.
  • It is an electronically controlled, Type 19, nonplanetary gear train, similar to the transaxle used in Hondas
import transmissions transaxles
IMPORT TRANSMISSIONS/TRANSAXLES
  • The transmissions and transaxles used in import vehicles are very similar to the domestic units.
  • They use planetary gears (with the exception of the Honda transaxles), multiple-disc clutches, bands, one-way clutches, hydraulic control systems, and lock-up torque converters.
  • A detailed description of their operation is normally available in the manufacturer’s service manual, transmission service manuals, and trade publications.

  • Toyota has used a variety of transmissions beginning with the two-speed Toyoglide.
  • It was replaced with three-and then four-speed designs.
  • Most of these designs are very similar.

summary
SUMMARY
  • There are many different automatic transmissions. They are easier to understand if the operation of the planetary gears and the application of the clutches and bands are understood.
  • Transaxles combine the transmission and final drive into one unit.
  • Each manufacturer uses specific transmissions and transaxles to meet the requirements of the vehicle it is used in.
summary1
SUMMARY
  • Some companies specialize in automatic transmissions and supply many vehicle manufacturers with their products.
  • Most automatic transmissions use planetary gearsets, but some vehicle manufacturers use CVT or constant-mesh transmissions.
