- 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 %. (Figure 2).
- 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.

Resetting PCM/TCM Adaptive Values on a Hyundai
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.
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 (refer to the service manual, but the average is about 200 degrees Fahrenheit).
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 (note: hold the accelerator pedal steady during upshifts).
* 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.
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 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.
How can I exit safe mode on my transmission?
Note: Sometimes, when the engine is turned off and restarted, a transmission that is in fail-safe (or limp mode) will repair itself. So, if you ever find yourself in this predicament, locate a safe spot to pull over and turn off the engine. Restart the engine after waiting one minute.
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. Call or visit Precision Transmission Exchange, Inc. right away for the leading transmission repair facility in Kenner, Louisiana.
Will transmission reset if battery is disconnected?
Will TCM be reset if the battery is disconnected? You would need to employ a transmission scan method to reset the TCM; simply unplugging the battery wouldn’t do it. It is not possible to complete this phase or resolve any gear shift problems by disconnecting the battery terminals.
How can I tell if my transmission needs repair?
There are always clunking noises when a car breaks down in movies, whether it’s a flat tire or a bad starter. The movies weren’t lying in this instance. Transmission issues may be indicated by strange sounds.
Don’t casually say, “Well, that’s new,” when your driving music suddenly changes.
Noises like clunking, buzzing, or whining are indicators of automatic transmission issues. Additionally, malfunctioning manual transmissions make loud, mechanical noises that seem to appear out of nowhere.
A clunking sound when shifting gears indicates a problem with the transmission. Have a mechanic examine it.
How much time does a transmission need to relearn?
It can take up to 90 days for the engine and transmission computer to recover your driving patterns when a battery is detached, or after a transmission replacement in your case. An automatic transmission typically won’t go into higher speeds until the engine coolant temperature reaches a certain level.
How does a transmission stop shifting?
The fluid characteristics of the transmission fluid can be impacted over time by the accumulation of dirt, debris, and other minute particles. This may result in the car dying when you change into drive or reverse, allowing a lack of power, a slipping transmission, jerky shifts, or even stopping the car from moving into gear at all.
Why is the limp mode on my Hyundai?
The security function in cars known as “limp mode,” or “limp home mode,” engages when the engine or gearbox control unit detects a fault. When a fault is detected, limp mode will limit the vehicle’s speed and turn off less crucial components like the air conditioning.
How long does a car computer take to reset?
Anyone can reset an ECU by removing the vehicle’s battery because it is a straightforward procedure. Please be advised that resetting an ECU often takes between 30 minutes and an hour, so make necessary preparations.
