You turn your car on to drive to work when you see the dread “check engine” light. Most people tend to ignore this light until they absolutely need to take their car into an auto shop. However, you may wonder what exactly has caused your “check engine” light to come on.
One possible option is that your vehicle has developed variable transmission problems. Your continuously variable transmission (CVT) provides seamless acceleration without gear shifts. If it malfunctions, that could have a significant impact on your car’s performance.
Here are three common variable transmission problems you may encounter and transmission maintenance tips.
1. Overheating
One of the most common CVT faults you will face is overheating. If your car overheats while idle, then it may be linked to your transmission.
Your CVT generates significant heat as it operates, and your transmission fluids are meant to help prevent it from producing too much. If it gets too hot, then it can have reduced performance and produce a burning smell.
To address overheating, start by checking the transmission fluid. Your dipstick should show you if it’s low. You can also tell if the fluid is still good based on its color.
A clogged cooler may be the cause of your CVT overheating. You’ll need to clean or replace it if necessary.
2. Slipping
CVT slipping is when the transmission fails to maintain a steady power output. As a result, your engine may rev higher than it needs to cause poor acceleration and reduced fuel efficiency.
This usually happens due to worn or damaged belts and pulleys. It may also happen if your car is low on transmission fluid.
Once again, it’s important to check your transmission fluid and refill it if it’s running glow. Contaminated fluid can also reduce your CVT’s ability to maintain proper pressure. Use the correct CVT fluid specified by your manufacturer if you do a fluid change.
You’ll also want to check for any signs of wear or damage. Replace anything that looks worn down.
3. Shuddering and Jerking
Your vehicle may shake during acceleration if your transmission struggles to maintain a smooth power delivery. Shuddering and jerking could be caused by anything from a worn-out belt to a malfunctioning torque converter. This could cause long-term damage to your transmission.
In addition to checking your transmission fluid and belts, have a professional take a look at your torque converter. Repair it if possible or pay for a replacement. Regular maintenance is key for preventing these problems and catching them before they cause an accident.
