The stator sends the fluid returning from the turbine to the pump. ... The stator resides in the very center of the torque converter. Its job is to redirect the fluid returning from the turbine before it hits the pump again . This dramatically increases the efficiency of the torque converter.
What is the function of a stator in a torque converter?
The stator keeps the transmission fluid, which is turning in the opposite direction of the engine, from hitting the converter housing and slowing it down . A torque converter also has a housing that is attached to the engine along with the impeller.
What is the stator connected to in a torque converter?
Stator. The stator sits between the impeller and turbine in the center of the torque converter, directly in the flow of oil exiting turbine and entering impeller. The job of the stator is to correct flow direction of fluid before reaching the impeller.
How does a stator multiply torque?
The stator redirects fluid from the turbine to the impeller, radically increasing the force of the fluid entering the impeller and multiplying the torque input from the engine . ... This creates the greatest speed difference between the turbine and the impeller and therefore the maximum torque multiplication.
What is transmission stator?
As the name indicates, the Stator (from Latin; one that stands) is the stationary part of a fluid device such as a torque converter . ... The torque converter assembly is a fluid coupling which transfers engine torque to the automatic transmission gear box.
Can you drive with a bad torque converter?
When a torque converter is not working, your car will have major problems. ... A bad torque converter can damage a transmission . Bad torque convertors can lead to damage, overheating, friction, and transmission fluid degradation. If these problems continue, it can cause even more damage to transmission.
How do you check 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.
How do you multiply torque?
- Multiply the force acting on the first gear by the first gear’s radius. ...
- Divide the second gear’s radius by the first gear’s. ...
- Multiply the gear ratio by the input torque that you calculated in Step 1: 2 x 600 = 1,200 newton-meters.
Why is torque multiplied inside a torque converter?
One of the characteristics of a torque converter is that it multiplies torque, by a factor of as much as two to two-and-a-half times or even more , depending on the design. Maximum torque multiplication occurs at rest, as the vehicle just starts moving. As speed increases, the torque multiplication decreases.
What is the torque multiplication factor in the torque converter with a stator?
The design of the stator will influence the torque multiplication characteristics of a converter, with a typical figure being in the region of 2.5:1 . The more drastic the change in fluid path caused by the stator from its ‘natural’ return path, the higher the torque multiplication ratio a given converter will have.
What are the signs of a bad torque converter?
When the torque converter starts malfunctioning, you may feel shuddering and even slipping in overdrive . You usually notice your car shuddering because it feels like it’s vibrating. Your car will vibrate even when you’re not going very fast. The shuddering makes the car lag and is very noticeable.
What happens when the stator is unlocked?
The stator’s overrunning clutch enables the stator to spin freely in one direction but keeps it from rotating in the other . If the stator’s one-way clutch spins freely while at low speeds, there will be a loss of torque multiplication, resulting in poor low-speed performance.
Which is better torque converter or CVT?
Modern automatics offer better fuel economy than manuals, thanks to a larger choice of drive ratios. ... Modern twin-clutch systems use seven gears, torque-converter autos are pushing as high as nine and CVTs can produce a near-infinite number of ratios, meaning they offer the best fuel economy.
Is a torque converter expensive to fix?
For starters, the torque converter costs between $150 to $350 . Therefore, if you are currently experiencing any of the symptoms of torque converter problems, you may need a good idea of how much it’ll cost to get it fixed or replaced. If you plan on fixing it yourself, then you’ll spend around $150 to $500.
Can you replace torque converter without removing transmission?
Can you replace torque converter without removing transmission? The good news is, if it is just your torque converter that is having issues since it’s a self-contained unit, you may not need to replace or rebuild your whole transmission. Torque converters can be serviced or replaced as a single unit .
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.
