What does a broken flexplate sound like?

Almost sounds like a rod knock, or perhaps a loose torque converter nut hitting the bellhousing or something. I also noticed that the car will "clunk" when it shifts into gear, and from first to second, and second to third. It's not a super loud noise, but sounds similar to a bad U joint.

How much does it cost to replace a flexplate?

What's the difference between flywheel and flexplate?

The flywheel is found primarily in vehicles that have a manual transmission, whereas the flexplate is found in automatic transmission vehicles. Both of these components are typically heavy, but the flexplate is much thinner and therefore lighter than the flywheel.

Can a cracked flywheel sound like a rod knock?

Yes a cracked or loose flexplate can sound like a rod knock.

What does a flexplate do?

The flex plate bolts to the engine crank shaft and to the torque converter of your automatic transmission. When the engine starts and is running the flex plate turns, which turns the torque converter and powers your hydraulic pump in your transmission. They sometimes will crack from just metal fatigue and vibration.

Where is the flexplate located?

A flexplate is mounted to the crankshaft and connects the output from the engine to the input of a torque converter. The torque converter is located between the flexplate and the transmission.

How long does a Flexplate last?

Slight misalignment may only cause a single flexplate to break in the life of the vehicle. More severe misalignment can break a flexplate in 15,000 to 30,000 miles.

How do I choose a Flexplate?

There are four main factors to consider when purchasing a flexplate.

1. The crank style: One or two piece rear main seal. ...

3. Ring gear tooth count: 153 or 168.
4. Internal or external engine balance.

What is a flex plate on a truck?

A flexplate (or flex plate) is a metal disk that connects the output from an engine to the input of a torque converter in a car equipped with an automatic transmission. It takes the place of the flywheel found in a conventional manual transmission setup.

What does a loose torque converter sound like?

Many noises can occur when your torque converter fails. While the current is relatively low, it will first seem like a whine, reminiscent of a power-steering pump. A series of clutches used inside the assembly with an overrun mechanism can cause damage if bad as this may result in a rattling noise when left unrepaired.

What does a broken torque converter sound like?

Whining or rattling noise:

Likewise, when a vehicle torque converter fails, the car will give a bad torque converter noise–a whining or whining sounds like a power steering pump with little or no fluid in it.

Should a torque converter rattle when you shake it?

Audible Clues. Your torque converter can make a variety of noises when it goes bad. You may first notice a whine, similar to a power-steering pump that is low on fluid. The stator within the assembly uses an overrun mechanism with a series of clutches that, when bad, can cause a rattling noise.

Can a torque converter cause rough idle?
