What is a flex plate on a truck?

Basically a flywheel or flex plate is the round metal disc shaped component that transfers power from the engine to the transmission. A flywheel is usually referenced to a car with a standard transmission,and a “flex plate” is used with automatic transmissions.

How much does it cost to fix a flexplate?

Based on all these factors, you can get your flexplate under $100 or for a couple of hundred dollars. Combine all of the factors mentioned above, and you safely total a cost of around $1200-$1500 to replace your flexplate.

What is the purpose of a flex plate?

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 happens when a flexplate fails?

The flex-plate can become cracked over time. As a result, this can cause it, to wobble. So, you might notice rhythmic clunking or grinding noises, while the engine is running. A misaligned flexplate, can also keep the engine, from running smoothly.

What causes flex plate failure?

Aside from a manufacturing defect, the only things that will cause a cracked flex plate are improper torque on the plate bolts at the crank and torque converter and the most common cause of transmission to engine misalignment; sometimes caused by missing alignment dowel pins that mate the transmission to the engine.

How long does a flex plate 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. Excessive crankshaft flange run-out or end plate can also cause flexplate cracking.

What does a broken flexplate sound like?

Noise. The classic and most obvious symptom of a cracked flexplate involves the sound it makes while the engine is running. Descriptions of the sound include clanking, chirping and a light knocking. The reason for the sound involves the flexplate's location and its function.

How much does a flex plate cost?

How much is a replacement flex plate? The flex plate or flywheel plate should cost somewhere in the region of $50-160, on average.

Is a flex plate a flywheel?

Basically a flywheel or flex plate is the round metal disc shaped component that transfers power from the engine to the transmission. A flywheel is usually referenced to a car with a standard transmission,and a “flex plate” is used with automatic transmissions.

How do I know if my flex plate is broken?

Symptoms of a bad flex plate

  1. Clunking, grinding, chirping, or rattling noises from rear of engine when engine is idling.
  2. Knocking noise when engine is shifted into drive or reverse.
  3. Heavy vibrations felt through the driver's seat when driving at normal speeds.
  4. Rough-running engine.
  5. Loss of power at higher speeds.

What is a flex plate made of?

Most flexplates are made of a thick piece of sheet metal with bolt holes for the torque converter and teeth for the starter. Manual transmission vehicles are equipped with a flywheel where the clutch assembly is mounted. The flywheel provides a smooth friction surface for the clutch disk.

What are flex plates made out of?

At its core, the flexplate is a simple metal disk that bolts between the crankshaft and torque converter with a ring of teeth that is engaged by the starter to physically spin the engine during cranking.

Do automatics have flex plates?

Flexplates are used to mount torque converters on automatic transmission vehicles. Torque converters replace the clutch of a manual transmission. A flexplate is mounted to the crankshaft and connects the output from the engine to the input of a torque converter.

How much is a Flexplate designed to be able to move?

The replacement cost of a flexplate can range from around $30 to over $800 depending on the engine and application. The average amount of time it takes to replace an engine flexplate is usually around 6-8 hours, based on the vehicle year, make, and model, as well as the engine size.

How much does it cost to replace a flywheel on a truck?

The replacement cost of a flywheel can range considerably. There are some flywheels which cost under $50 while others cost as much as $400 or more. It all depends on what type of car you drive, how durable the flywheel is, and whether the part is an exact OEM replacement or aftermarket.

Whats the difference between flexplate and flywheel?

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.

How often should automatic transmission fluid be changed in a vehicle?

Manual transmissions generally need transmission fluid changes more frequently than automatic transmissions. The average recommended interval for manual transmissions is around 30,000 to 60,000 miles. For automatic transmissions, the recommended interval is around 60,000 to 100,000 miles.

Is flywheel part of engine or transmission?

Is The Flywheel Attached To The Motor Or Transmission? The flywheel extends from between the engine and the transmission via a clutch, pressure plate, and throw out bearing in an engine with a standard transmission.

How much does it cost to replace a cracked flywheel?

On average, flywheel replacement cost is anywhere between $600 to $1,100. You can save yourself a lot of coins if you did the replacement by yourself but only attempt that if you're an experienced mechanic.

How much does it cost to replace a torque converter?

Most auto repair shops will charge someone anywhere from $600 to $1000 for a torque converter replacement job. If you would rather do the replacement job yourself, then a new torque converter will cost anywhere from $150 to $500. The exact cost depends on the make and model of your vehicle.

What does loose torque converter bolts sound like?

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.

How do I check my flex plate?

Start the engine and let it idle. Slide under the vehicle with a stethoscope, and place the stethoscope probe against the underside of the bell housing. Any noise emanating from the this region indicates a problem with the flexplate and/or torque converter-flexplate combination.

Will a bent flexplate cause vibration?

Vibration will sometimes occur at all speeds owing to warped flexplates, especially when they have not been balanced.

Why does my flexplate keep breaking?

The following causes for cracked flexplate failures: 1) Out of balance engine or torque converter. 2) Bad starter drive can cause teeth or ring gear to wear rapidly or break off. Teeth can also break when engine is running and starter is engaged.
