Did it ever occur to you that on cars built in the last 15 years develop engine repair problems or have a transmission failure because the TCM, transmission control module is the culprit? In essence the newer the car the more operations are computer controlled, making the entire system a team that needs to work together. One lazy team member hurts the performance of the other properly performing teammates.

A transmission control unit (TCU), also known as a transmission control module (TCM), or a gearbox control unit (GCU), is a type of automotive ECU that is used to control electronic automatic transmissions. Similar systems are used in various semi-automatic transmissions, purely for clutch automation.

A Transmission Control Module (TCM), also known as a Transmission Control Unit (TCU), is an electronic device that controls the automatic transmission in your vehicle. Sensors and data provided by the Engine Control Module calculate various components that identify how well your car or truck is performing. A transmission control module or TCM is an essential electronic device presented in all modern vehicles with an automatic transmission. The transmission control module gathers data from the engine and transmission to make the gear shifting in the transmission.

Driving with a faulty transmission control module can cause serious problems for your transmission and engine down the road. Don’t think twice about replacing the faulty device—order a transmission control module replacement from CarParts.com! We offer OE-quality parts for a. Your vehicle’s Transmission Control Module is a vital component of any road-going vehicle that runs on an automatic transmission system. Most modern automobiles come with a TCM unit, which is handy compared to relying on mechanical or hydraulic control.

To put it mildly, only a fool would ignore the TCM and related components anytime your automobile transmission acts up. I say this because gradually over the last 15 or so years cars operate all functions through a computerized system. The operations commanded by a computer are ever increasing. Very advance systems need computers that are more involved in your cars drive ability.

Computers develop isolated problem areas that only affect one part of the car, and in some cases a computer can have a total failure. Which may have a profoundly bad effect on your engine or transmission. Either way, the TCM will need replacing. Since all TCM modules are solid state circuitry and sealed in epoxy, mere mortals can not fix them.

FYI: The best choice in searching for computer is not the dealer. It is your trusty transmission replacement supplier. Since the TCM, or onboard computer is an integral part of the direct performance of your car, it is logical to call the premier transmission suppliers for a used low-mileage TCM. Since they have access to the same cars that the used transmissions come from. Meaning that the preponderance of low mileage wrecked have good computers in them. Realistically speaking, some of the new cars or trucks have computers that control the engine and transmission and suspension, which can cost from about 500 dollars new to close to 1000 dollars from the dealer. Most engine supply companies have access to used TCMs for about 100 dollars. What is interesting is that in most cases you get the same guarantee a new one would get for much more money. One year…

As a starting point, if a transmission repair is needed, the first thing your mechanic should do is hook up a scan tool and test the ECM, TCM and every input, sensor, module, controller, etc. on the car. So many times it turns out that the problem does not require you to replace the engine or transmission, or if replacement is needed, the ECM or TCM transmission control module may be the culprit. So, in essence, you can put a replacement transmission in your car and still have a problem.

The company that stands out to me is GotTransmissions.com. Mostly because the owner Brian knows about the issues of dealing with computers and has made a point of having access to low mileage ECMs and related components for pennies on the dollar. In fact if you were to call them for any reason, in the course of the conversation, your representative would discuss the computer with you.

Be a wise consumer, ask the technician at the repair shop checking out your car if the electrical system has been scanned or is going to be. If the answer is anything less than “right now”, take your business to another shop.

BTW, if the only part your car needs is an TCM, call GotTransmissions.com, an insightful company thinking in advance to deliver the critical parts that get you on the road asap. Call us @ 866-320-1182, we will gladly sell you a computer only.

A Transmission Control Module (TCM), also known as a Transmission Control Unit (TCU), is an electronic device that controls the automatic transmission in your vehicle. Sensors and data provided by the Engine Control Module calculate various components that identify how well your car or truck is performing. The TCM is responsible for functions including the optimal time to switch gears, monitoring fuel economy and emissions, and shift quality.

The age of your TCM plays a factor in how the unit functions. Modern day TCMs receive signals from several sources including engine sensors, automatic transmission sensors, and other controllers that determine how to run the transmission in the most efficient way. Older TCMs typically have dedicated inputs and sensors on the controlled engine components, whereas more modern units will gather information from a shared input.

The complexity of modern TCMs are unique to each make and model, and each calculation is based on a number of parameters — the end goal being to optimize the efficiency of your transmission.
