The development of the electronic automatic transmission and the embedding of more electronic systems brought a huge progress to the area.

The transmission's operation is also controlled by computers. These computers are known as the automatic transmission control units (TCU) and it uses sensors to receive information from the ECU

The computer processes and calculates this Information in order to determine its operation such as the nature and timing of gear changing.

In addition, computer embedding allows precise control of the vehicle's operation and the ability to change its attributes according to the software changes.

The main purpose of the automatic transmission is to simplify the act of driving.

The Vehicle Lab has a large inventory of transmissions and parts
