INTRODUCTION:

 

Most of modern cars now use an automatic transmission, whether a former hydraulically controlled or a recently electronically controlled, as the driver is exempt from the effort of changing gears (or shifts) manually, as well as pressing on the clutch pedal. And thus avoid possible operating mistakes and the consequences for the damage to the transmission devices, and become parts in which the driver controls is the accelerator pedal and stick to change the car movement either forward or backward only.

Here it is needed to study the principles and basics of the automatic transmission of both types. And also know the problems and malfunctions which are expected to occur either due to damage or failure in any inner mechanical part or failure in the hydraulic circuit which is responsible to transfer and move the transmission fluid or finally any failure in the electronic circuit.

As long as we are talking about failures in mechanical parts, then we have to study the internal mechanical parts and construction of (planetary gears and torque converter and the servo devices of brake bands and clutches, etc.)

Also as we talking about the hydraulic circuit problems, then we have to study the basics of hydraulic pressure and force movement through transmission fluid. And the different types of fluids and their properties and its condition.


In addition to having some problems in the electronic circuits, So we should study the different types of sensors and how to recognize their own faults.
