How Does a transmission Work?

Your vehicle’s automatic transmission is a remarkable piece of machinery. It may be complex to understand how it functions, but a little knowledge can go a long way toward preventing a breakdown

A short drive to a nearby store means your transmission will likely shift about 25 to 30 times. Now imagine how many trips like that you make in a year and the impact they have on your transmission.

The most complex and intricate system in your car is its automatic transmission – understanding how it works can help save you time, hassle, and money. Comprised of a series of mechanical, hydraulic, and electrical components, they are all controlled by your car’s engine control unit, aka the powertrain control module.

All Transmissions Are the Same….Aren’t They?

Not at all. While the basic principle or function hasn’t changed, the inner workings have changed by leaps and bounds. The transmission of 50 years ago is nothing like the complicated engineering of today.

So What Happens Inside My Transmission?

Automatic transmission gear changes are monitored and executed by your vehicle’s internal computer. A torque converter uses the pressure and flow of transmission fluid to not only regulate the gear changes but also to allow the engine to continue running even when at a full stop. It also makes for a smoother shifting between gears.

When fluid levels in the transmission drop, so does the pressure that controls the shifting of gears. That can cause friction and less effective cooling, in turn leading to damage and potentially expensive repairs.

Recognizing Automatic Transmission Warning Signs

Preventing a breakdown from stranding you at the roadside requires insight into the warning signs your car will send if you’re on the cusp of experiencing a transmission-related problem.

These warning signs include:

  • Grinding, rattling, or whining noises when changing gears or problems shifting gears
  • A delay in movement or your car jerks or shakes as it accelerates
  • Your transmission fluid is low, or you notice it pooling beneath the engine where you park
  • If you check your transmission fluid and see it’s not a reddish color
  • You smell a burning odor while or after you drive


How much will a new transmission cost me?

No way to tell… at least, not yet. Not until the problem has been checked thoroughly by one of our qualified technicians. After performing those tests, our technician will be able to tell you whether you’re dealing with a problem inside the transmission, or a problem in the vehicle systems that control transmission operation.




But then he’ll be able to give me a price, right?

Well, no… not completely just yet. If the problem is in the computer system, the technician will probably have to perform additional diagnosis to identify the specific cause of the problem. That may take a half hour, or may take a few hours, depending on the problem. Once we’ve identified the specific problem, we would be able to give you an accurate estimate of the cost to fix your car.

If the problem is inside the transmission, we will be able to give you a rebuild price based on the type of transmission and the transmission repair option you choose. If your preference is a custom-rebuilt transmission they’ll need to disassemble and inspect the transmission in order to give you a firm price.

The good news is that the vast majority of transmission problems that come into the shop these days don’t actually end up needing a new transmission. The repairs may end up costing less than 25% of the price of a rebuilt transmission.

And rest assured, saving our customer unnecessary repairs or expenses is our priority, and how we keep lifelong customers.


Are your transmissions stocked on a shelf?

No, unlike many of our competitors, we go through the vehicle’s original transmission. By doing this, it ensures correct fitment


Do you offer a warranty?

Of course!, Our rebuild service comes with a one year warranty
