Dual-clutch transmission problems (Top 3)

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

DCT transmissions, which are also known as dual-clutch transmissions used in multi-speed vehicle transmission systems, have two separate clutches for odd and even gear sets.

Dual-clutch Transmissions are a type of automated manual transmission and have a global reputation for quality, reliability and durability but there are some common problems with DCT transmission.

What are the common problems with dual-clutch transmissions?

Most of the common problems with dual-clutch transmission are:

  • Jerking and hesitation
  • Shaking and shuddering
  • Transmission overheating
  • Loud and unusual noises
  • Delayed shifting

Why is Jerking and hesitation a problem with dual-clutch transmissions?

Sometimes dual-clutch transmissions do not function properly due to shifting solenoid failure or wear and tear; that is why jerking and hesitation is a problem with dual-clutch transmissions.

What are the signs of this problem with the dual-clutch transmission?

You would immediately notice and sense jerking and hesitation while dual-clutch transmission is shifting from one gear to another as this is one of most important issues with dual-clutch transmission.

How to solve this dual-clutch transmission problem?

Firstly try replacing the shifting solenoid valve bodies, 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 Shaking and shuddering a problem with dual-clutch transmissions?

Because shaking and shuddering would mean the dual-clutch transmission is not functioning smoothly as these 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 dual-clutch transmission?

How to solve this dual-clutch 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 Transmission overheating a problem with dual-clutch transmissions?

Because Dual-clutch mechanical components tend to get damaged, worn, and malfunction under high heat levels. This results in lower than the acceptable performance from the vehicle and high fuel consumption as well as lowering the life of the gearbox.

What are the signs of this problem with the dual-clutch transmission?

Generally when a dual-clutch transmission overheats an error is shown. This error is not immediately visible on the screen but requires a diagnostic tool to get these actual error codes.

How to solve this dual-clutch transmission problem?

Check the transmission oil and its level. If it is too low then fill the required amount of oil in the transmission. If it is too dirty, then drain the entire oil from the transmission and fill it again.

While driving on road if you experience a delay in response while pressing the throttle or shifting from one speed to another speed then this could result in an unpleasant drive for you. So, this is a problem with your dual-clutch transmission.

What are the signs of this problem with the dual-clutch transmission?

Usually you would instantly notice this sign of the problem as you get a hesitation sensation or slow response from the car when you try to shift.

How to solve this dual-clutch transmission problem?

Resetting the software settings or checking the gear ratio sensors could be a solution. Also, visiting the nearest service center or your trusted mechanic would be the only way to solve this problem because this might be a serious transmission problem you are facing.

How to precisely diagnose these common problems in dual-clutch 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 BMW E96 transmission fully electronically controlled automatic transmission.
