Shift Lever Lock Mechanism
Shift lever lock systems are adopted to prevent mis-operation of the shift lever. With this mechanism, when the shift lever is in the “P” range, the shift lever cannot move unless the ignition key is Read more Shift Lever Lock Mechanism
What is Sensors/Switches?
The sensors/switches play the role of collecting the types of data used to determine the various controls, and convert them into electrical signals, which are then transmitted to the Engine & ECT ECU. Read more What is Sensors/Switches?
Operation of Automotive Gear Shift
Each gear condition is explained using the solenoid valves and shift valves.
1. 1st gear
For gear shift from neutral to 1st gear, the fluid passage to C1 is opened by switching the manual valve. Read more Operation of Automotive Gear Shift
What is an Automotive Axle?
The axle supports the wheels. Therefore, the axle varies in design according to the type of suspension and power train (FF, FR, 4WD, etc.). The axle shaft supports the wheel and transmits the drive torque Read more What is an Automotive Axle?
What is a Valve Body?
The valve body consists of an upper valve body, and a lower valve body. The valve body resembles a labyrinth, containing many passages through which the transaxle fluid flows. Many valves are built into Read more What is a Valve Body?
What is an Automotive Limited Slip Differential ?
The LSD is a mechanism that limits the differential when one of the wheels begins to slip and generates an appropriate drive force in the other wheel to allow the vehicle to drive smoothly. There are various Read more What is an Automotive Limited Slip Differential ?
Major Components of Oil Pump
The oil pump is driven by the torque converter (engine) to supply the hydraulic pressure that is required for the operation of the automatic transaxle.
HINT:
Use the dipstick for fluid level inspection, Read more Major Components of Oil Pump
Hydraulic Control Unit
The clutches and brakes that operate the planetary gear unit are operated by hydraulic pressure. The hydraulic control unit generates and adjusts this hydraulic pressure and switches its passage. The illustration Read more Hydraulic Control Unit
Types of Planetary Gear Unit
There are various types of planetary gear units. Here, typical planetary gear units are:
1. 3-speed + O/D type (FF vehicles)
By combining a 3-speed planetary gear unit with an O/D gear unit, four Read more Types of Planetary Gear Unit
