How does the torque converter work? The torque converter casing connects to the flywheel, spinning at the same rate as the crankshaft, within the housing of the turbine. The impeller or centrifugal pump effectively flings the transmission fluid into the fins of the turbine that in turn spins or transmits the torque into the transmission.
How does a 2500 rpm stall converter work?
With that, if you take a car with a 2,500 RPM stall converter and you hold your foot on the brake hard, and hit the gas at the same time, (as if you were going to power brake), the "general" RPM in which the tires will break loose is at "about" 2,500 RPM.
What causes a torque converter to fail?
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.
What happens when a torque converter locks up?
Torque converter lock-up is engaged through a solenoid mounted inside the transmission. This clutch acts just like a clutch disc in a manual transmission application. When the converter is “locked up” this clutch is forced against the front of the converter creating a direct drive from engine to transmission.
What can go wrong with a torque converter?
Symptoms of Torque Converter Problems
Related question for How Does The Torque Converter Work?
Is a torque converter sealed?
Torque converters are sealed units; their innards rarely see the light of day, and when they do, they're still pretty hard to figure out! The torque converter in an automatic transmission serves the same purpose as the clutch in a manual transmission.
How does a torque converter fill up?
How do I know if my converter is stalling?
Will a torque converter cause a vibration?
Lockup torque converters were added to many newer-model vehicles to help with fuel economy. However, vibration problems can happen when these torque converters go bad. The vibration felt is known as "lockup shudder" and may occur due to a bad engine or transmission as well.
How long does it take to fix a torque converter?
How long 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 is a 4500 stall converter?
Stall means when the car is on the starting line, (with say a 4,500 RPM stall converter), and the trans brake is on, (which locks the transmission in first and reverse at the same time), and you hit full throttle, the engine will wind-up to 4,500 RPM with the car just sitting there, so when you slip your finger off the
Why is a high stall torque converter used on a performance car?
A higher stall torque converter will let your car accelerate better because the car will be taking off at the rpm range where it is making the most power. But you don't want a stall speed that is too high either. Camshafts can affect performance by altering your torque curve. An engine producing 230-lbs.
Does a stall converter help?
Stall converters allow the car to launch in it's torque curve and get off the line much harder than a car that has much less stall.
How do I choose a torque converter stall?
When choosing the stall speed that is right for your application, a rule of thumb is that the advertised stall speed will need to be at least 500 rpm higher than the beginning of the camshaft's powerband. All aftermarket camshafts are delivered with a recommended RPM operating range.
What causes high stall speed?
Factors such as total weight, load factor, power, and center of gravity location affect stall speed—sometimes significantly. Stall speed increases as weight increases, since wings need to fly at a higher angle of attack to generate enough lift for a given airspeed.
Can you pull an engine with the torque converter?
If you try to separate the transmission from the engine in the car, with the torque converter still attached, you have to be able to perfectly separate the two along that linear line, until the input shaft clears the torque converter, allowing the engine to be lifted up and out.
