GMC Acadia transmission problems

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

GMC Acadia has an automatic transmission and does not require any manual input to shift gears while driving as most of the cars have automatic transmission. Various sensors and mechatronic systems work in coordination to shift gears automatically. 

Automatic transmissions have a global reputation for quality, reliability and durability. However, there are many problem with automatic transmissions and we’ll tell you why and how you can solve them

What are the common problems with GMC Acadia transmission?

Some of the most common problems with GMC Acadia transmission are:

  • Torque converter malfunction
  • Shift solenoid failure
  • Transmission slippage
  • Hesitation and jerking
  • Difficulty shifting gears

Why is Torque converter malfunction a problem with GMC Acadia 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 GMC Acadia 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 GMC Acadia 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 Shift solenoid failure a problem with GMC Acadia transmissions?

Shift solenoid malfunction means there is a problem with the gear shifting. An GMC Acadia 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 GMC Acadia transmission?

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

How to solve this GMC Acadia  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.

Why is Transmission slippage a problem with GMC Acadia  transmissions?

GMC Acadia 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 GMC Acadia 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 GMC Acadia  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 Hesitation and jerking a problem with GMC Acadia transmissions?

Because hesitation and jerking would mean the GMC Acadia transmission is not functioning smoothly as automatic transmissions are designed for and also they are meant to be a smoother drive than manual. This could cause a very unpleasant driving and passenger experiences

What are the signs of this problem with the GMC Acadia transmission?

Jerking itself can be taken as a sign of this GMC Acadia automatic transmission problem because automatic transmissions are not meant to jerk when loaded or accelerated.

How to solve this GMC Acadia transmission problem?

Visiting your trusted mechanic or service center at the earliest is possibly the only way to fix this issue as the internal mechanical components or dampers might be worn out and it requires experience and expertise to repair this problem.

Why is Difficulty shifting gears a problem with GMC Acadia transmissions?

You would want a seamless and easy shift even at low throttle input, so if your GMC Acadia 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 GMC Acadia transmission?

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

How to solve this GMC Acadia 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.

How to precisely diagnose these common problems in GMC Acadia transmission?

If you need to precisely diagnose these common problems then you need to use a diagnostic tool which is software based and can be connected to the vehicle electronic system as GMC Acadia transmission fully electronically controlled automatic transmission.

How to prevent getting these problems in the first place?

To prevent these problems, you need to change the GMC Acadia transmission oil as per the manual or when it is too dirty. This is the easiest and most effective way to take care of your vehicle transmission and also drive your vehicle in a recommended way.

FAQs: GMC Acadia transmission problems

Does GMC Acadia have transmission problems?

Yes, many GMC Acadia owners have been reporting issues with their transmissions not working properly from as early as 20,000 miles into ownership. Some drivers have complained about a shuddering in their vehicle when they accelerate or shift gears while others experience that the transmission will not go into gear at all.

How long does a GMC Acadia transmission last?

The average GMC Acadia transmission gets around 100,000 miles with proper maintenance. GMC Acadia transmissions were troublesome in 2008, but that issue has since been resolved in newer models.
