To account for typical clutch wear over the course of the transaxle’s lifetime, the PCM or TCM has circuitry to modify solenoid duty and line pressure as necessary. This bulletin outlines the steps required to “relearn” and reset (erase) the PCM/TCM adaptive values.
Warning: To improve the shift quality condition after replacing a transaxle or resetting the PCM/TCM, undertake this procedure to reset and relearn the adaptive learning.
In order to deliver the best shift quality, the PCM/TCM adaptive values must be adjusted following the completion of the following repairs:
I. Use GDS to reset PCM/TCM adaptive values:
1. Select the VIN and A/T menu after attaching a GDS. view Figure 1
2. Choose “Option Treatment” from the home screen.
3. Choose “Resetting Auto TIA values” and adhere to the on-screen instructions.
II. Regain Values of Adaptation:
Note: An “adaptive learning” method must be carried out after the adaptive values have been reset (erased).
4. Select VIN and A/T and attach a GDS.
5. Choose “Throttle Position” and “Current Data.”
6. Continue to drive the car until the ATF temperature falls within the indicated range. see chart
7. Request a helper to keep an eye on the GDS. While the transmission shifts through gears 1-2-3-4-5-6, accelerate from a standstill at the stated IPS standard, then slowly come to a stop. Take a five-second break. Five times, please.
Perform the extra steps listed below if more adaption is required:
8. Make a series of downshifts (5-4, 4-3, 3-2, and 2-1) while opening the throttle only slightly to moderately.
10. While the car is still, shift from P to N to D and back again, pausing for three to five seconds in each gear. Five times, please.
Note that only the ATF temperature ranges depicted in the chart experience adaptive learning.

Resetting a transmission control module: Some helpful hints
A transmission control module’s primary goal is to precisely give the appropriate engine modifications to ensure the car’s engine performs at its best.
- It can be reset by turning off the power for more than five minutes, then turning it back on.
- It is possible to repeat it five times to fully warm the engine, but you should not do it in cold weather.
- You should reset the transmission control module after every six months because it improves the car’s performance. Some automobiles require resetting every three months.
- It takes the engine five minutes to warm up sufficiently to operate at peak efficiency when it is cold.
- It can be reset by simply turning off the engine and taking the key out of the ignition. You can unplug the battery for a while and then reconnect it. In some circumstances, though, the power supply should be left off for a further five minutes.
- You must change the automatic gearbox gear at least twice after starting the car.
- In manual transmission vehicles, three shifts between forward and reverse are required. The transmission control module must be automatically reset after at least 10 miles of continuous gear shifting.
- By unplugging the module’s battery or removing fuses from the fuse box, you can stop the power supply to the module. However, in some vehicles, it requires removing a relay that is attached to the module.
How Can a Transmission Control Module Be Reprogrammed?
Any car with an automatic transmission system must include the transmission control module. Newer automobiles have a transmission control module (TCM), as opposed to older ones, which relied on mechanical or hydraulic control over a transmission system.
It is unlikely that a transmission control module would ever need to be replaced, thus understanding how to reprogram one is only important if one becomes problematic.
Disconnecting the battery terminals and allowing the system to run dry for five to thirty minutes is the standard procedure for reprogramming a transmission control module. The TCM ought to be reset when the battery is reconnected.
The module is utilized to transmit data to the vehicle’s other computer systems and ensure that your gearbox is always in the optimal gear for maximum fuel efficiency and performance.
Hyundai provides a reset/relearn trans.
To reset and relearn adaptive learning after replacing a transaxle or reprogramming the PCM/TCM, a special method is needed.
To account for typical clutch wear over the course of the transaxle’s lifetime, the PCM or TCM has circuitry to modify solenoid duty and line pressure as necessary. Adaptive values need to be adjusted in order to provide the best shift quality following the replacement of an automated transaxle, programming, or exchanging a PCM/TCM from another vehicle.
Select the VIN and A/T menu on the Hyundai GDS. Choose “Option Treatment” from the home screen. Choose “Resetting Auto T/A values” and adhere to the on-screen instructions. For ten seconds, turn off the ignition. The adaptive learning method must be finished once the adaptive values have been reset (erased). Choose A/T and VIN. Select “Throttle Position” and “Current Data.” Once the ATF temperature is within the desired range, continue to drive the car.
Ask a helper to keep an eye on the GDS tester. Referring to the service handbook, accelerate slowly to a stop as the transmission shifts through gears 1-2-3-4-5-6 while maintaining the specified TPS angle (10-13% to 25-35%) for the specific model. Continue to stand still for five seconds, then carry out this acceleration/deceleration process five more times.
* Make multiple consecutive downshifts (5-4, 4-3, 3-2, and 2-1) while opening the throttle only little to moderately.
* Perform a number of 6-4, 5-3, and 3-1) skip shifts with moderate to wide throttle opens.
* While the car is still, shift from P to N to D and back, pausing for three to five seconds in each gear. Then do it five more times.
How can my Hyundai transmission be reset?
- Following the clearing of the shift-adapt values, the adaptive learn technique must be carried out as outlined below.
- To make sure that the prerequisites for relearning are met, connect a scan tool to the car and keep an eye on the temperature of the transmission fluid and the TPS %.
- Drive from a stop at the stated TPS %, allowing the transmission to shift through all the gears once it hits the lowest parameter for transmission fluid, and then gradually slow down to a halt. Take a five-second break. Five times, please.
- Keep the accelerator pedal steady throughout all upshifts, please.
Follow these extra procedures if more adaption is required:
- Execute a series of modest to medium throttle opening forced downshifts (5-4, 4-3, 3-2, and 2-1).
- Perform a number of forced downshifts at medium to large throttle openings (5-3, 5-2, and 3-1). Move the shift lever from P to N to D and back, halting for three to five seconds in each gear, with the car stopped and the brake pedal applied. Five times, please.
- Move the shift lever from P to N to R and back, halting for three to five seconds in each gear, with the car stopped and the brake pedal applied. Five times, please.
Without a scanner, how can a transmission control module be reset?
- Step 1 is to turn the key. The first thing you should do is insert your key into the ignition and turn it on and off twice to turn on all of the dashboard lights.
- Step 2: Step your foot onto the gas.
- Step 3: Exit the car and let off the gas.
- Step 4: Hold off.
- Prepare to drive in Step 5
How is a transmission control module repaired?
Normally, transmission control modules cannot be repaired. Simply replace them if they are defective. If the TCM is the issue, a new TCM is required.
How come you would reset your transmission?
Relearning is required when any transmission component is changed or when a transmission service is performed. This technique should be followed, for instance, while replacing the transmission control unit, solenoid, transmission fluid, or clutches. Reset and relearn procedures must be carried out in order to avoid transmission failure after a fluid change.
Is it possible to alter a transmission control module?
You could observe a number of signs indicating your module needs maintenance, including:
- shifting that is unpredictable, especially when the check engine light is on
- difficulty changing into a higher gear
- difficulties downshifting
- You’re in the same gear forever.
- shifting takes longer
- Too often, even while not going very far, the transmission overheats
- The sensation of slipping or catching gears
- When accelerating, the car’s engine makes a loud roaring noise.
- You observe a significantly reduced gas mileage
Any of these signs could indicate that your TCM requires professional maintenance. There are a few different solutions to fix the problem and get you back on the road if you’ve determined that the TCM is broken. Let’s consider whether option is ideal for your car: replacing the TCM or reprogramming it.
What is the cost of repairing a transmission control module?
A transmission control module will cost between $500 and $900 to replace. The cost of the labor should be between $50 and $200, while the cost of the parts should be between $450 and $700.
Of course, you may order a new TCM online and inquire about a mechanic’s labor charges per the hour. The cost of the parts themselves, which can vary widely depending on the car manufacturer, makes up the majority of the cost of this replacement process. Taxes and other fees will also be included in the final cost.
Does the transmission need to be reprogrammed?
Transmissions were operated without the aid of electronics for the first several decades of the history of the automobile. That’s just not the situation anymore. No matter what kind of car, truck, or SUV you drive, Precision Transmission Exchange, Inc. in Kenner, Louisiana, has the expertise and tools required to handle even the most complicated transmissions.
The majority of vehicles that need this won’t shift at all until being linked into specific software, and this is true for many vehicles once a new transmission is fitted. This implies that even if your vehicle has a brand-new transmission, it is still essentially useless without the proper technology to configure it.
Programming isn’t solely required for brand-new applications. Reprogramming the transmission is the last stage in fixing many problems and completing repairs. On some vehicles, a transmission code must be punched in and reset if it is thrown for any reason. Even though it might seem like an unnecessary nuisance, this is actually a fantastic and cutting-edge answer to a number of other problems.
First off, programming a transmission is an easy process that doesn’t take a lot of time if you have the necessary tools and knowledge. Second, programming or reprogramming a transmission guarantees that everything is operating as it should—correctly, according to specification. The safeguards and programming requirements incorporated into your system help to ensure that your transmission isn’t unduly damaged as a result of a malfunction. Your transmission is a complicated and intricate component.
Our professionals can program a transmission or reprogram it for you if necessary. We have everything you need, regardless of your repair or maintenance requirements, to keep your gearbox shifting smoothly for many years to come.
