How can I tell if my torque converter is bad or my transmission?

Is it my torque converter or transmission?

Almost no one thinks of it, but when you drive your automatic transmission car, you're master over your car's torque converter. That's because torque converters transfer the power your car engine makes to the transmission in your car. Hence, you've commanded your torque converter every time your car shifted gears.

How do you test a torque converter?

Put the pedal to the metal While pressing on the brake pedal, press the accelerator to the floor for two to three seconds. Don't exceed five seconds, or you risk blowing out the transmission. The RPM the engine maxes out at is the stall speed.

Will a torque converter throw a code?

Will a bad torque converter throw a code? Sometimes, but not always. Most torque converter-related codes have to do with the torque converter clutch. Other issues with the converter are less likely to set a code.

Will a bad torque converter cause shifting problems?

Slipping

A torque converter can slip out of gear or delay a shift its fin or bearing is damaged. This is because the torque converter changes the engine's torque into hydraulic pressure that is required to ship the transmission's gears.

3 Signs of a Bad Torque Converter shudder slips makes humming rattling whirring whinning noise

What causes torque converter failure?

Many torque converter failures can be caused by excessive friction, which means the torque converter's needle bearings are damaged. Also, a faulty seals or faulty clutch solenoid can be to blame. A faulty seal can allow fluid to leak and become contaminated. A bad torque converter can damage a transmission.

How much does it cost to fix a torque converter?

Most auto repair shops will charge someone anywhere from $600 to $1000 for a torque converter replacement job. If you would rather do the replacement job yourself, then a new torque converter will cost anywhere from $150 to $500. The exact cost depends on the make and model of your vehicle.

How many hours does it take to replace a torque converter?

The torque converter itself is relatively inexpensive (between $150 and $350, depending on the vehicle), but 5-10 hours of labor is involved since the transmission must be removed in order to replace the torque converter.

What happens with a bad torque converter?

Bad torque converters can cause overheating, friction damage, and transmission fluid degradation. The longer these problems continue, the more damaged your transmission will get.

What is a torque converter shudder?

Torque Converter Shudder occurs when the clutch inside the converter on an automatic transmission is being applied and the transition from slipping to locked up does not occur smoothly.

Can a bad torque converter cause engine to stall?

If the torque converter fails, the engine can stall. There are several reasons why the converter could fail, such as overheating or dirty fluid. If you have a manual transmission, the car is more likely to stall from the clutch. When stopping, you may forget to engage the clutch or switch into neutral gear.

What does a bad torque converter sound like?

Whining or rattling noise

When you drive your car for a long, you should tell when something is wrong by listening to the car noise. Likewise, when a vehicle torque converter fails, the car will give a bad torque converter noise–a whining or whining sounds like a power steering pump with little or no fluid in it.

How do I know if my transmission pump is bad?

What are the symptoms of a bad TCC solenoid?

The main symptom of a TCC solenoid failure is the converter is not locking up. When the converter is not locking up you will notice the engine's RPMs staying higher under load at highway speeds. Another symptom of a failed TCC solenoid is a fault code.

Can a bad torque converter cause rough idle?

Rough Idling

Rough idling is another common symptom of a bad torque converter. If you feel that your idle is a bit jumpy and sometimes too low and sometimes too high, it could be a torque converter problem.

Why does my car feel like it wants to turn off when stopped?

As you drive, the forward speed of your vehicle forces more air past the filter and into the engine - but when you come to a stop, the engine stalls due to air starvation. An air starvation problem in your engine could also be caused by a mass airflow sensor.

Can a torque converter cause loss of power?

poor vehicle performance: a bad torque converter can cause poor acceleration. lack of power at lower speeds is usually caused by the stator spinning incorrectly, resulting in lack of torque.

What does transmission shudder mean?

When the fluid in a transmission becomes dirty and contaminated, the particles in the fluid prevent it from building up enough pressure in the transmission lines. In turn, this will prevent proper pressure contact between transmission plates when they are applied. As a result, the transmission will begin to shudder.

Why does my transmission slip when I accelerate?

Transmission gears wear out and start slipping.

Worn or rounded out gears don't properly link together so this can cause a bumpy shift and slippage as you accelerate and drive.

What would be the most likely cause of a transmission vibration?

Grinding, Shaking and Other Bad Vibrations

Transitions into gear and between gears will cause some vibration at first; but then, as the problem persists, gear changes become more jarring and cause shaking. You should take your car to an AAMCO shop to be checked and serviced.
