What happens if torque converter bolts loose?
Loose Flyweel Bolts The mass of the torque converter acts like a flywheel, smoothing out engine pulses. The ring is integral to inexpensive flexplates but can often be removed and replaced on flywheels. A loose bolt on a flexplate or a crack between the bolt holes can result in the same knocking or rattling sound.
How do you know if your torque converter bolts are loose?
I have seen on occasion the torque converter bolts get loose and cause a knocking noise that sounded very much like loose engine parts. So if you have a knocking noise and an automatic transmission, it’s a good idea to check the torque converter bolts to see if they’re tight.
What do loose torque converter bolts sound like?
Loose Converter A loose torque converter can sometimes sound like piston slap or a rod knock, but it’s actually just the TC hitting the flywheel. While this definitely isn’t good, all your technician typically has to do is tighten the bolts, as long as nothing else has been damaged yet.
How does a bad Flexplate sound?
Here are some of the warning signs of a bad flex plate: Clunking, grinding, chirping, or rattling noises from rear of engine when engine is idling. Knocking noise when engine is shifted into drive or reverse. Heavy vibrations felt through the driver’s seat when driving at normal speeds.
Why is my torque converter not working properly?
This will in turn cause the transmission to overheat. This is one of the most common causes of torque converter problems. If the transmission fluid is dirty and old it won’t be able to do its job as a hydraulic fluid as well.
How is a torque converter different from a clutch?
The biggest difference between a torque converter and a clutch is how they transfer the energy between the flywheel (what a clutch connects to) or the flex plate (what a automatic transmission connects to). The clutch will slip using physical friction between the clutch disk and flywheel.
Why does my washer sound like a torque converter?
It spins around and the washer sounds like it is beating itself to death. The torque converter is the same way when it can’t spin the right amount of fluid through itself. It is way less likely, but the bolts that hold the torque converter to the flex plate can come loose and cause a vibration at speed.
How much does it cost to replace a torque converter?
Torque converter replacement cost is going to depend a lot on what type of vehicle you are driving. In general, a front wheel drive vehicle is going to be more expensive from a labor point of view and could cost anywhere between $300-$1000 depending on the vehicle.
