How do you determine stall speed on a torque converter?
Ideally you want the stall to lock up somewhere close to the peak torque of the engine. Typically engines that produce more low-end torque will increase the stall speed. The same converter will stall at a lower rpm behind a less torquey – higher rpm engine.
What failures can occur in torque converters?
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 if your torque converter fails?
A malfunctioning torque converter can have a shudder that comes from the transmission. Its job is to smoothly convert engine torque into hydraulic pressure that your transmission uses to engage and shift gears. When the torque converter starts malfunctioning, you may feel shuddering and even slipping in overdrive.
Can torque converters be repaired?
It is not usually possible to repair other parts or, rather, they cannot be bought as new ones, but only take from another torque converter. Therefore, the general rule is that the torque converter can only be repaired if its body is both inside and out a whole and the blades are not damaged.
Are there any problems with the torque converter?
A very common problem is that the torque converter bearings will get worn out. This does often not cause any slipping or other problem with the transmission, but it can create bearing noises from the transmission.
What causes the gears to slip on a torque converter?
If there isn’t enough pressure to control the flow of the hydraulic transmission fluid, too much or too little will get into the transmission and cause the gears to slip as it shifts. This can often be due to low or bad fluid as well, so be sure to check that first.
What should be the RPM of a torque converter?
In you select a 2700-3000 converter, it should be able to footbrake stall the torque converter to about 2700 rpm considering the automobile setup. Typically this would increase your RPMs from a dead stop by 500-1500, giving you a significant increase in vehicle acceleration.
Why does my torque converter spin like a propeller?
Underneath the cover of the torque converter is a pump which contains a bunch of blades. These blades spin like a propeller in sync with the engine crankshaft. This causes fluid from the transmission to flow onto the blades of the impeller.
