Torque converter 20050640

The more it rotates, the more pressure it creates inside the unit, and the more power is transferred from the engine to the transmission.

For example, if you run two fans against each other and start one of the fans, the other fan will also begin to rotate, but not directly at the speed the other fan has. This is precisely how a torque converter works. As you can probably figure out, this gives you a very smooth power transmission between the engine and the wheels.

When it comes to torque converters, some common problems can be encountered. In general, the torque converter is not a very advanced part of older vehicles, and there are not many parts that could fail.

A widespread problem is that the bearings in the torque converters are worn. This does not cause slippage or other transmission problems but can cause bearing noises from the transmission.

If you hear bearing noises from the transmission, check the transmission fluid, and see if you can see metal parts inside the transmission fluid.

If you find metal parts, they are probably from a defective torque converter bearing. A faulty seal of the torque converter will cause the transmission fluid to leak out of the torque converter, and thus the pressure inside the converter will be lost. Low pressure inside the torque converter will cause slippage, overheating, and other strange symptoms.

This is actually one of the most common problems when it comes to a faulty torque converter. There are several clutches in a torque converter. If the torque converter is locked in the drive or idling gear and does not release the transmission, you most likely have a problem with the converter clutch. A faulty torque converter clutch can also cause other symptoms such as slipping and rough acceleration. The torque converter clutch solenoid is a common part that fails within the automatic transmission.

The solenoid valve controls the fluid pressure of the hydraulic transmission, which enters the lock-up clutch. There are not many things you can do to test the torque converter without taking it apart. But there is a way to check the torque converter for signs of wear. This can take a long time, and it is recommended to check the temperature of the transmission oil with a diagnostic scanner to make sure that the transmission oil is warm.

Now you can try to apply the drive gear and listen carefully if you can hear any signs of noise from the torque converter. The torque converter should move the car forward with just a light touch of the accelerator pedal.

Shift between the other gears Drive and Sport, if you have it to see if you can hear any other sounds from it. If everything seems to be fine, you can go on to the next step. Keep an eye on the tachometer and speedometer. If the car revs up significantly without actually accelerating, the torque converter is slipping. All older automatic transmissions slip a bit when accelerating, but if you have owned the car for a while, you probably know how much it should slip.

If you are not sure, let a mechanic test drive your car and see if he hears any noise or can feel slipping. Some older American cars have a cover plate that you can remove to inspect the torque converter. But even with them, you will not see much because the torque converter is a sealed unit. I do always recommend to remove the torque converter from the transmission to diagnose it properly. The transmission does often have to be removed to replace or inspect the torque converter for any problems.

To replace the torque converter, it will take between hours, depending on your skills and experience. A good repair manual will save you both time and money. Check out the best options here.

Certified Automotive Diagnostic Technician. Car was running fine.

Sitting at a light it started vibrating alot before I could get home it felt like transmission fell from bottom. Howdy, I have a F 4x4 with a 5. Trans was replaced by the dealer at 86k miles with a used 50k mile unit, at k now. Replaced the filter and fluid after I had it for a few months. Don't know which Torque Converter they put in, original, used that came with the trans or new.
