Automatic Transmissions

Automatic transmission service is maintenance that is often ignored. Automatic transmission service intervals will vary across different makes and models and is also affected by how the vehicle is driven.

Auto trans servicing includes:

  • Changing transmission fluid
  • Replacing internal or external filter (where applicable)
  • Checking for leaks in transmission, trans cooler and lines
  • Road testing for shift pattern and driveability problems
  • Adjustments where applicable.

Ever wonder how your transmission knows to shift gears? Why is it that when you stop, the engine doesn’t die? We’re here to show you how cars work.

Automatic transmissions – they’re pretty much black magic. The sheer number of moving parts makes them very difficult to comprehend. Let’s simplify it a bit to get a basic understanding of how it all works in a traditional, torque converter-based system.

Your engine connects to your transmission at a place called a bell housing. The bell housing contains a torque converter for automatic transmission-equipped vehicles as opposed to a clutch on manual vehicles. The torque converter is a fluid coupling whose job it is to connect your engine to your transmission and thus to your driven wheels. The transmission contains planetary gearsets which are in charge of providing different gear ratios. To get a good understanding of how the whole automatic transmission system works, let’s have a look at torque converters and planetary gearsets.
