CVT transmission problems (The Top 5)

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

Continuously Variable Transmission or CVT seamlessly shifts through unlimited range to gear ratios while driving. However, there are many problems with CVT transmissions and we’ll tell you how you solve them.

What are common CVT transmission problems?

Most of the common CVT transmission problems are:

  • Overheating
  • Slipping
  • Sudden loss of acceleration
  • Shuddering
  • Loud noise during acceleration

Why is overheating a CVT transmission problem?

Because overheating causes the CVT transmission to function ineffectively and also causes a lot of internal friction between the belts and pulleys while engaging and disengaging.

What signs are shown as a result of this CVT transmission problem?

A few common signs are slow response while accelerating and not getting the desired drive when needed. Also, you could see some sort of malfunction sign on the dashboard. 

How to fix this CVT 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.

Why is slipping a CVT transmission problem?

Because you would not be able to get the desired amount of acceleration when you press the throttle pedal and also the engine would consume excess gas to overcome the slipping of CVT transmission.

What signs are shown as a result of this CVT transmission problem?

You get a feel while accelerating that the CVT transmission is not responding as it should under normal circumstances. This is usually the common sign you get as a result of this CVT transmission problem.

How to fix this CVT transmission problem?

You have to visit your trusted mechanic or service center  to solve this CVT transmission problem. As this is a mechanical problem and requires extensive expertise, it is better if you visit the mechanic.

Why is sudden loss of acceleration a CVT transmission problem?

As your car is accelerated by using its belt and pulleys and torque converter which is the part of the CVT transmission, therefore if you experience a sudden loss of acceleration it is definitely due to the transmission.

What signs are shown as a result of this CVT transmission problem?

Usually you would instantly notice this sign of the problem as you get no response from the car when you press the throttle pedal. 

How to fix this CVT transmission problem?

Visiting the nearest service center or your trusted mechanic would be the only way to solve this problem because this might be a serious CVT problem you are facing. 

Why is shuddering a CVT transmission problem?

Because shuddering would mean the CVT is not functioning smoothly as CVT transmissions are designed for a smoother drive than manual. Therefore if you’re experiencing shuddering when you accelerate then it means your CVT has a problem.

What signs are shown as a result of this CVT transmission problem?

Shuddering itself can be taken as a sign of this CVT transmission problem because CVTs are not meant to shudder when loaded or accelerated. 

How to fix this CVT transmission problem?

Visiting your trusted mechanic or service center at the earliest is possibly the only way to fix this issue as the weights that control the pulleys might be worn out and it requires experience and expertise to repair this problem.

Why is Loud noise during acceleration a CVT transmission problem?

Because hearing a loud noise while accelerating is not normal and it means something inside the CVT transmission has broken or misaligned. 

What signs are shown as a result of this CVT transmission problem?

If you hear a loud and irregular noise when accelerated then it is a sign that your CVT transmission is not working as it should or something has failed.

How to fix this CVT transmission problem?

It is suggested to visit a service center immediately as this might be major mechanical failure inside the CVT transmission and this might be the only way to fix this issue.  

How to diagnose these common CVT transmission problems precisely?

WIth a manufactured recommended diagnostic software tool which can be plugged to the transmission control unit, you can precisely get the error code for your CVT transmission problem you are facing.

As nowadays, cars and their major systems are controlled electronically with various mechatronic and processors working together. That is why it is possible to use these software diagnostic tools and find the help of the error code received, find the cause and solution to the problem.

How to prevent getting these problems in the first place?

The most important thing you can do is to first keep the CVT transmission fluids up to the required levels. Also, maintaining the quality of the transmission fluid is also equally important to prevent getting these major CVT transmission problems in the first place.

FAQs: CVT transmission problems

How long do CVT transmissions last?

CVT transmissions can last almost as long as a traditional automatic transmission and are made to last the full life of the vehicle. The typical CVT has a life expectancy of at least 100,000 miles. Certain models like the Toyota Prius commonly last well over 300,000 miles.

Why are CVT transmissions so bad?

CVTs have the tendency to be at high rpm, which causes the engine to rev more under acceleration. Also, You won’t feel it when the CVT vehicle shifts gears because it has no gears in the first place which can be a poor feel
