CVT transmission problems symptoms

In this brief guide, we are going to provide you with the common CVT transmission problems symptoms 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 problem symptoms with CVT transmissions and we’ll tell you how you solve them.

What are the common symptoms of CVT transmission problems?

Most of the common symptoms of CVT transmission problems are:

  • Unusual Noises
  • Burning Smell
  • Leakage 
  • CVT slippage
  • Delayed Movement

Why are Unusual Noises a symptom of CVT transmission problems?

Because hearing loud or unusual noises while accelerating is not normal as these CVT transmissions are not designed and built to make such noises. 

What is the cause of this symptom for the CVT transmission problem?

So, it means something inside the CVT transmission has broken or misaligned. If you hear such loud and irregular noises when accelerated then it is a sign that your CVT transmission is not working as it should or something has failed.

How to solve 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.  

Why is Burning Smell a symptom of CVT transmission problems?

Because CVT  transmission 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 is the cause of this symptom for the CVT transmission problem?

When you smell something burning then usually it is when a CVT transmission overheats and 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 CVT transmission problem?

After cooling down the transmission check the gearbox oil for its condition. Change it if it is too thick and completely black. Also, check your clutch if it is the problem behind this malfunction.

Why is Leakage a symptom of CVT transmission problems?

Modern CVT transmissions are leakage proof systems and if anything is leaking out of them then it is definitely a sign of a problem which may cause serious trouble for you in the future. 

What is the cause of this symptom for the CVT transmission problem?

Fluid pressure sensors will sense a low pressure and this is the cause that there is not enough fluid and a leakage somewhere in the transmission. You would get an error such as P0842 or errors in the similar range which are associated with transmission fluid pressure.  

How to solve this CVT transmission problem?

Finding where the leak is and closing it, is the most obvious solution to fix this sign before it causes mechanical damage to your car. Usually the gaskets or the seals in the transmission are worn out or broken to cause a fluid leak.

Why is CVT slippage a symptom of CVT transmission problems?

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 is the cause of this symptom for the CVT transmission problem?

The cause of this symptom is that the CVT belt and pulleys are worn out or damaged. This is usually the common cause of this CVT transmission problem.

How to solve 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 are Delayed Movements a symptom of CVT transmission problems?

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 slow or no response it is definitely due to the transmission.

What is the cause of this symptom for the CVT transmission problem?

The cause usually is an issue with the transmission sensors or fluid sensors. You would instantly notice this sign of the problem as you get an hesitation sensation from the car when you try to shift. 

How to solve 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 transmission problem you are facing. 

How to precisely diagnose these common symptoms of CVT transmission problems?

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 symptoms

What is the average lifespan of a CVT transmission?

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

How do I know if my CVT transmission is going bad?

Following are the warning signs of problems  in CVT Transmission:

  • Leakage: If you see pinkish oil leak marks when you move your car out of the parking area in the  morning, it is a common sign of trouble with CVT transmission.
  • Vibration: bucking or shaking feel while driving at high speeds is a sign of CVT problem.
  • Delayed Drive: When you press the throttle and do not get the desired response then it is a sign of a problem.
  • Burning Smell: If you smell something burning in the car, it is also a sign of a CVT transmission problem.
  • Transmission Slips: If you feel the car is not shifting properly, this is also a sign of a CVT problem.
