Isuzu AMT transmission problems

In this brief guide, we are going to provide you with common problems with Isuzu AMT transmission and what you can do to rectify these problems before they worsen.

Isuzu AMT has automated manual transmission and does not require any manual input to shift gears while driving. Various sensors and mechatronic systems work in coordination to shift gears automatically. 

Automated manual transmissions have a global reputation for quality, reliability and durability. However, there are many problems with automated manual transmissions and we’ll tell you why and how you can solve them

What are the common problems with Isuzu AMT transmission?

Some of the most common problems with Isuzu AMT  transmission are:

  • Torque Converter Malfunction
  • Incorrect gear ratio
  • Transmission slippage
  • Difficulty shifting
  • Shift solenoid malfunction

Why is Torque Converter Malfunction a problem with Isuzu AMT transmissions?

If your torque converter or if you are not getting the desired response when you release the brake and press the throttle pedal then you are most definitely experiencing torque converter engagement or disengagement problems.

What are the signs of this problem with the Isuzu AMT  transmission?

Firstly you would be unable to stop the car when releasing the throttle pedal for disengagement problem and secondly for engagement from even if you press too much throttle the car will not move forward.

How to solve this Isuzu AMT  transmission problem?

If the clutch of the torque converter is worn out then you need to replace it or else the solenoid might be broken which also might need replacing. In the worst case the entire assembly needs to be replaced if the state of the torque converter is beyond repair.

Why is Incorrect gear ratio a problem with Isuzu AMT   transmissions?

If the Isuzu AMT transmission is with an incorrect gear ratio then it can cause anything from shift solenoid problems to transmission fluid problems.

What are the signs of this problem with the Isuzu AMT  transmission?

P0730 is the code that will be shown if there is an incorrect gear ratio with the Isuzu AMT transmissions. This is a generic code which you will get using OBD-II for your transmission.

How to solve this Isuzu AMT  transmission problem?

Wires connecting sensors to the transmission control module and other electrical connections should be inspected and any damaged or corroded wires in and near the transmission control module should be repaired or replaced to fix this issue.

Why is Transmission slippage a problem with Isuzu AMT transmissions?

The Isuzu AMT transmission system is not designed to slip and if you are experiencing slippage then it could cause slow response or further damage to the transmission system. So, it is definitely a sign of a problem with the mechanical components of the transmission.

What are the signs of this problem with the Isuzu AMT transmission?

You will be able to hear the gear slip while driving and this would be a good sign if there is slipping. Also, an error code will be displayed if you use a diagnostic tool.

How to solve this Isuzu AMT transmission problem?

The solenoids of the two gears might be worn out and need to be replaced. Also, there is a chance that these solenoids might also be broken. Rarely, complete mechanical failure occurs with these transmissions.

Why is Difficulty shifting a problem with Isuzu AMT  transmissions?

You would want a seamless and easy shift even at low throttle input, so if your Isuzu AMT transmission is shifting harshly or with difficulty even at low speed then there is definitely a problem.

What are the signs of this problem with the Isuzu AMT transmission?

You would immediately notice and sense if the Isuzu AMT transmission is shifting with difficulty from one gear to another as this is one of most important issues with Isuzu AMT.

How to solve this Isuzu AMT transmission problem?

Firstly try replacing the transmission pressure sensor, if that doesn’t work then check for an oil leak in the servo assembly of the particular gear. These are primarily two fixes for this problem.

Why is Shift solenoid malfunction a problem with Isuzu AMT transmissions?

Shift solenoid malfunction means there is a problem with the gear shifting. A Isuzu AMT transmission changes gear by directing pressurized transmission fluid to move clutches and bands around. The computer controls all of this with little spring-loaded devices called solenoids.

What are the signs of this problem with the Isuzu AMT  transmission?

P0750 is the code that will be shown if there is a shift solenoid malfunction with the Isuzu AMT transmissions. This is a generic code which you will get using OBD-II for your transmission.

How to solve this Isuzu AMT  transmission problem?

Some common solutions are changing the transmission fluid and filter or replacing faulty solenoids. Also you can repair or replace a faulty transmission pump.

How to precisely diagnose these common problems in Isuzu AMT  transmission?

To properly diagnose these problems, you need a scan tool to read these codes from the Transmission Control Unit. Firstly, If a Isuzu AMT transmission is malfunctioning, it immediately informs the driver with an error message on the screen.

How to prevent getting these problems in the first place?

Regularly changing your gearbox oil and other lubricants may save you a lot of trouble and money in the future. Although many experts suggest different number miles for servicing, your car manual will give you a proper recommendation when you should change. The best way to prevent these problems is to avoid buying these cars in the first place as these cars are known to have  transmission problems. 

FAQs: Isuzu AMT transmission problems

Is AMT a good transmission?

Yes and as the newer cars that are coming with the AMT transmissions tend to have better transmission, better pickups and overtaking capabilities and moreover they come in with hill hold assist and hill descent control in the AWD version.

Is AMT good or bad?

An AMT is as good as an automatic car, even in high traffic. Actually, when AMTs were first launched in some of the affordable cars, many users found it difficult to push the accelerator to move the car forward in stop-go traffic and then use the brake pedal to bring it to a stop.

Conclusion
