In this brief guide, we are going to provide you with common problems with Lexus CVT transmission and what you can do to rectify these problems before they worsen.
CVT or Continuously Variable Transmission for seamless shifts through unlimited range to gear ratios while driving. However, there are many problem symptoms with IVT transmissions and we’ll tell you how you solve them.
Lexus CVT Transmissions are a type of Continuously Variable Transmission and have a global reputation for quality, reliability and durability but there are some common problems with Lexus CVT transmission.
What are the common problems with Lexus CVT transmission?
Some of the most common problems with Lexus CVT transmission are:
- Transmission fluid leakage
- Lack of response
- Torque converter malfunction
- Burning smell
- Shaking and grinding
Why is Transmission fluid leakage a problem with Lexus CVT transmissions?
Lexus CVT transmissions are very advanced and leakage proof systems and if anything is leaking out of them then this could cause transmission overheating. It is definitely a sign of a problem which may cause serious trouble for you in the future.
What are the signs of this problem with the Lexus CVT transmission?
You would get an error such as P0842 or errors in the similar range which are associated with transmission fluid pressure. If these sensors get a low pressure this will indicate there is not enough fluid and a leakage somewhere in the transmission.
How to solve this Lexus CVT transmission problem?
Detecting 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 Lack of response a problem with Lexus CVT transmissions?
While in the vehicle on road if you experience lack of response while pressing the throttle then this could result in an unpleasant drive for you. So, this is a problem with your Lexus CVT transmission.
What are the signs of this problem with the Lexus CVT 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 Lexus CVT 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.
Why is Torque converter malfunction a problem with Lexus CVT 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 Lexus CVT 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 Lexus CVT 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 Burning smell a problem with Lexus CVT transmissions?
If you get a burning odor, your Lexus CVT transmission fluid is probably overheating due to clutch debris, breakdown of metallic components and sludge. So this sign is a cause for concern.
What are the signs of this problem with the Lexus CVT transmission?
The smell itself should be a good sign that there is something wrong with your Lexus CVT transmission. However you will get a more detailed sign if you use a software diagnostic tool.
How to solve this Lexus 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. Also check for any debris and discarded materials.
Why is Shaking and grinding a problem with Lexus CVT transmissions?
Because shaking and grinding would mean the Lexus CVT transmission is not functioning smoothly as CVT 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 Lexus CVT transmission?
Shaking itself can be taken as a sign of this Lexus CVT CVT transmission problem because CVT transmissions are not meant to shudder when loaded or accelerated.
How to solve this Lexus CVT 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.
How to precisely diagnose these common problems in Lexus CVT 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 Lexus CVT transmission fully electronically controlled CVT transmission.
How to prevent getting these problems in the first place?
To prevent these problems, you need to change the Lexus CVT 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: Lexus CVT transmission problems
How long do Lexus CVT transmissions last?
Lexus CVT transmissions last just as long as a traditional automatic transmission and are designed to last the full life of the vehicle. The typical CVT has a life expectancy of at least 100,000 miles. However, this number is entirely dependent on the care and maintenance of the car.
Is the Lexus CVT transmission reliable?
A CVT gearbox does not have many moving parts, so it’s relatively reliable. It’s also mainly used in low-power applications, so cars running a CVT are usually fairly unstressed.
