What happens when the stator is locked?
During low-speed operation, the stator locks, creating a vortex. The redirected flow assists the impeller resulting in torque multiplication. On the other hand, if the stator’s clutch freezes up and remains locked continuously, the vehicle suffers poor high-speed performance.
What causes a torque converter to lock up?
A cold engine temperature: There are cases where the converter may not lockup except the coolant temperature reaches 120°F. Lockout of the overdrive unit: An overdrive unit that is locked-up causes the torque converter lockup to also be locked out.
Can a torque converter lock up an engine?
Recently developed torque converters have had a “lockup” feature added to reduce this energy loss and improve mpg. This lockup feature will not engage until the vehicle reaches approximately 40 mph. Other factors may also prevent this type converter from locking up.
What happens when you change the stator on a torque converter?
Change the characteristics of your torque converter with a quick stator swap! Altering the vane angle and count has a big effect on how a converter works. The primary component of stall speed is the angle of the stator, the secondary component is the number of vanes.
Is there one stall speed for a torque converter?
None of them are wrong; there is no one stall speed for a converter because it’s infinitely variable.” Besides the stall speed of the converter, the size of the converter is crucial in how it will work with the car overall. Every car will require a different size converter based on the power output of the engine and style of racing.
What happens if the torque converter is contaminated?
Being a fluid coupler, your car’s torque converter relies on transmission fluid to operate correctly. If the fluid becomes contaminated, anything that uses and relies on the fluid can be damaged. Contaminated transmission fluid can cause damage to your converter parts and your transmissions parts.
Where is the stator clutch in a car?
The stator clutch is located inside the vehicle’s torque converter. It’s critical to the operation of the torque converter and the overall drivability of the vehicle.
