Buy Transmission Control Module !EXCLUSIVE!
These parts are built to last, but over time your transmission control module might possibly succumb to a combination of heat fluctuation, overuse, and other day-to-day forces. This could leave the part in poor condition and prevent it from performing its duties reliably. Some of the most common signs of a bad transmission or control module include:

CARDONE Remanufactured Transmission Control Modules are engineered for quick installation and no comebacks. Each unit is engineered to meet or exceed O.E.M performance. All modules are 100% computerized tested and resolder of critical components, as well as 100% replacement of common ware components, ensuring superior electrical connections.
The transmission control module (TCM) is a vital component of any vehicle with an automatic transmission system. Rather than relying on hydraulic or mechanical control over a transmission system, newer vehicles use a transmission control module instead.
The purpose of the transmission control module is to help the automatic transmission choose the best gear to be in at any given time. That way, the driving performance and fuel economy will be at the optimal level.
If the Check Engine warning light (or transmission warning light) illuminates on your dashboard, it could mean several things. But if you notice any problems with your shifting in addition to the Check Engine light being on, then it is most likely a problem with your transmission control module or some other component of your transmission system.
In any event, get your vehicle checked out immediately by a mechanic or use your own scan tool to check for any Diagnostic Trouble Codes (DTC). If code P0700 shows up, you may have a problem with your transmission control module.
Since an automatic transmission system relies on the transmission control module to do the shifting, a bad transmission module will cause incorrect or unintended shifting. This can prove to be anything from an annoyance to causing a serious accident.
Problems with your transmission system usually result in bad fuel economy. An automatic transmission is designed for optimal gear selection and timing to provide you with the best possible fuel economy.
Another option is to repair your TCM. The transmission control module repair cost will in almost all cases be lower than replacing with a new module. On average, expect to pay around $300 to repair your transmission control module.
Does it jerk when you let your foot off the brake? Automatic transmissions have a parking pawl that engages to keep the vehicle from rolling when you put it in park. Does it still jerk when you have the parking brake on?
There was a transmission fluid loss because of a worn out seal about 3 years back and car had stopped moving completely. That issue was fixed by putting a new line. Car has been running fine since then until a few days back.
Is a transmission module part of a new or replaced transmission. I replaced my transmission on a 2015 Altima about 10 months ago. Now I am told my the module is bad for another $1500 because the car is jerking. Just like it did when the transmission was replaced. Pls advise. Thanks.
I have a 2006 Chevy Impala. I had the alternator changed and when I drove it after, it went 2-3 miles and all of a sudden had trouble shifting gears. Seems to be stuck in a low gear, tach moves, but car does not. Never had any transmission trouble until this. Any thoughts
I have a 2021 Fiat 500X Sport. I took it to my authorized deal under warranty bc I was given a warning ticket for speeding and according to my speedometer I was driving within the posted speed limit. I also noticed I was getting horrible fuel mileage. Fast-forward to 30 days later I was told that the factory programmed my car for the wrong diameter size tire that was causing a higher rate of speed and they are also going to replace the transmission module. Would either one of this issues effect the milage? My odometer is reading approx 7700 and I estimate that it should be closer to 5000 miles.
This condition only happens after the vehicle has warmed up (driving for a bit), but does not do it while cold (for some reason). I have flushed the transmission on multiple occasions (on recommendation), but no luck.
I have a 2014 Ford Focus, took it in and it was the transmission control Module it was repaired and four days later it went out again dash states transmission fault check now. Why would it do that. It was serviced at a Ford dealership
Hello what could be the problem when 2018 Gmc. Transmission is put in park after engine turn off my truck and to roll backwards this is a first time problem and no other problems with this transmission. Thanks
It sounds like the parking pawl inside the transmission might be broken. You will probably have to drop the transmission to have it serviced. It would be best to consult with a transmission shop for more information and a quote.
A transmission control module is an electrical control unit or computer that is used to control electronic automatic transmissions. Transmission control modules, or TCMs, use sensors in the vehicle and data from the engine control unit to determine when to shift gears.
The transmission control module determines the best time for your vehicle to change gears. Based on data it receives from the rest of the vehicle, the TCM tells your transmission when to upshift or downshift.
The best way to check and test a transmission control module is to observe how your vehicle is driving. If your car is having problems, the TCM could be involved. Here is a list of possible symptoms that could indicate that your transmission control module has gone bad.
The check engine light indicates a problem with your vehicle, including transmission control module problems. If the check engine light is on, take your vehicle to your local mechanic so they can run a diagnostic scan.
If your vehicle shifts when you did not intend it to, or shifts into gears that you did not want it to, you may very well have problems with your transmission control module. For example, if you are driving at a low speed and your vehicle suddenly shifts into neutral for no reason, there could be something wrong with your TCM.
If the circuitry of the transmission control module was not soldered correctly, the TCM could fail prematurely. As with any such problem, if your vehicle is brand new or still under warranty, you could ask the manufacturer to pay for fixing the problem.
Faulty wiring between the TCM and other vehicle control modules can cause the TCM to short, meaning it was overloaded and burnt out. Vehicle electronics systems are very sensitive, and an overload of voltage or amperage can certainly cause components of this type to fail. Keep an eye out for any frayed, decayed, or severed wires around the TCM.
Install the new transmission control module by doing the opposite of what you did to remove the old one. You should use the same bolts and screws and ensure they are tight and snug to install correctly. Attach the wiring to the data port.
If you do the work yourself, the only cost involved will be the cost of the new transmission control module itself. Depending on the make and model of your vehicle, this could range from as low as $40 at a junkyard to $300 to $500 online. If you go to a mechanic, the additional cost could be anywhere from $50 to $200 for their labor and shipping costs.

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 conjunction with various semi-automatic transmissions, purely for clutch automation and actuation. A TCU in a modern automatic transmission generally uses sensors from the vehicle, as well as data provided by the engine control unit (ECU), to calculate how and when to change gears in the vehicle for optimum performance, fuel economy and shift quality.
Electronic automatic transmissions have been changing in design from purely hydromechanical controls to electronic controls since the late 1980s. Since then, development has been iterative and today designs exist from several stages of electronic automatic transmission control development. Transmission solenoids are a key component to these control units.
The evolution of modern automatic transmission and the integration of electronic controls have allowed great progress in recent years. The modern automatic transmission is now able to achieve better fuel economy, reduced engine emissions, greater shift system reliability, improved shift feel, improved shift speed and improved vehicle handling. The immense range of programmability offered by a TCU allows the modern automatic transmission to be used with appropriate transmission characteristics for each application.
The typical modern TCU uses signals from engine sensors, automatic transmission sensors and from other electronic controllers to determine when and how to shift. More modern designs share inputs or obtain information from an input to the ECU, whereas older designs often have their own dedicated inputs and sensors on the engine components. Modern TCUs are so complex in their design and make calculations based on so many parameters that there are an indefinite amount of possible shift behaviours
This sensor sends a varying frequency signal to the TCU to determine the current speed of the vehicle. The TCU uses this information to determine when a gear change should take place based in the various operating parameters. The TCU also uses a ratio between the TSS and WSS which is used to determine when to change gears. If either the TSS or WSS fails or malfunctions/becomes faulty, the ratio will be wrong which in return can cause problems like false speedometer readings and transmission slipping. To test these parts, check the resistance to make sure it's within manufacturer specs. 041b061a72
