By knowing how to prevent torque converter problems, you will have better control over your car’s reliability and performance.
The purpose of this blog post is to discuss what happens when a torque converter goes bad, the potential causes of these problems, and practical ways to prevent a torque converter from malfunctioning.
Article Summary
What Happens When A Torque Converter Goes Bad?
The torque converter is a part of an automatic transmission. It sits between the engine and the vehicle’s transmission.
The torque converter uses engine oil in the middle of it to multiply the torque from the engine and transfer it to the transmission.
When the torque converter starts to fail, your vehicle will experience all sorts of problems. The car’s drive ability might become poor, and it may not accelerate as smoothly as before.
Symptoms of A Failing Torque Converter
Before failing, a torque converter shows some malfunctions in various ways. All the parts are not working accurately. Symptoms of a failing torque converter are.
Slipping Transmission
One of the most obvious symptoms of a failing torque converter is a slipping transmission, also known as sudden jerks while driving or a slight lag in the take-off when you hit the accelerator.
This indicates that the torque converter is not transferring the power from the engine to the transmission properly.
Runaway torque
A problem with the torque converter can cause the transmission to overheat.
Since the converter helps maintain the pressurized fluid within the transmission, a failure can result in increased temperature, possibly triggering the warning light for transmission overheating.
Shuddering or Vibration
If you feel shuddering or a noticeable vibration when motoring when the vehicle is in gear, or particularly when accelerating, then the torque converter lockup may not be working properly due to trouble with power flow.
Poor Acceleration
A slipping torque converter can result in poor or sluggish acceleration. If your vehicle seems to bog down when starting from a stop or struggles to pick up speed when you accelerate, then your problem could be a slipping torque converter.
Whining or Grinding Sounds
Certain malfunctions in a torque converter can result in unusual noises such as humming, whining or even grinding sounds.
These noises are often present when the converter is not managing to engage or disengage properly.
Illuminated Check Engine Light
A damaged torque converter can sometimes trigger the check engine light in your dashboard. While the light can be caused by many different issues, you may want to take your vehicle in to be serviced if it comes on.
Causes of Torque Converter Failure
As soon as the torque converter starts to malfunction, your engine starts to slip, the transmission overheats, and fuel might be wasted, eventually leading to poor acceleration.
There are several causes for a failing torque converter. Some of them are described below.
Wear and Tear
The internal components of the torque converter may simply wear out, especially if the car has gotten a lot of use and is older.
The clutch in the converter may wear out, or one of the bearings, stator, or other components might need to be replaced.
Fluid Contamination
People often overlook the importance of fluid contamination when it comes to torque converters. That neglect would be foolish since dirty or low transmission fluid can contaminate the converter.
The latter burns from a combination of too much friction and a lack of cooling. That’s why solenoid to converter leaks can often be traced back to transmission fluid.
Faulty Torque Converter Clutch
The torque converter operates through a clutch that locks and unlocks to control engine power. When this clutch fails, it can cause the engine to slip and underperform.
Overheating
This can result from too much friction if the transmission overheats, scorching the torque converter and other critical transmission components.
But regular maintenance and ensuring your cooling system is well looked after will help to avoid this.
Mechanical Issues
Issues inside the torque converter, such as a broken stator or turbine, can lead to its failure.
What to Do if You Suspect A Bad Torque Converter
Seek Professional Help: If you experience any of the culprits mentioned above, take your vehicle to your mechanic for a proper diagnosis so that you can ascertain whether the torque converter is also the culprit.
Regular Maintenance: Keep your torque converter trouble free by maintaining your vehicle according to the manufacturer’s suggested tuning fluid change and another transmission related service schedule.
Act Fast: If you discover a problem, correct it before the transmission (and other parts) suffer from any more damage.
Prevention for What Happens When a Torque Converter Goes Bad
A bad torque converter may arise thousands of problems to your car. So, to avoid these problems you should follow the described preventive measures.
Regular Fluid Checks and Changes
- Action: Check and replace the transmission fluid every 30,000 to 45,000 miles, or as per the manufacturer’s recommendations. Clean fluid does a better job of keeping the torque converter, which lives in the transmission, lubricated and cooled, which prevents it from overheating.
- Advantage: keeps the system in good working order and minimizes pump driven, fluid related damage to the torque converter and transmission.
Monitor for Signs of Trouble
- Action: Pray to the God or spirit you believe in for your car to slow down. A gentle hand from on high could be all that stands between you and catastrophe creating warped heads or a warped head creating catastrophe. Pay close attention to any unusual behavior (slipping, overheating, weird noises). The earlier you spot warning signs, the better your chances of avoiding a serious breakdown.
- Advantage: conducting repairs on a torque converter early, before the damage worsens, will save you money and preserve the lifespan of your torque converter.
Maintain Cooling System
- Action: Make sure the coolant is properly circulated through the cooling system. The transmission cooler is an integral part of it.
- Advantage: Stops the torque converter and the automatic transmission from overheating, which can cause premature failure.
Avoid Excessive Towing and Heavy Loads
- Action: In accordance with your vehicle’s towing capacity, avoid exceeding the recommended load, whether by carrying or towing.
- Advantage: Less strain on the torque converter and transmission, which helps avoid undue wear and damage.
Practicing these precautions will help maintain your torque converter for as long as possible and prevent issues that might wreck your ride.
