Flex Plate Information
A functioning Mopar Flex Plate will send power from the transmission to the driveshaft at the same time softening vibration.
The perfect parts, like a Mopar flex plate, are just a click away when you order from PartsGeek. By enabling your injectors to use gas more completely, performance components increase horsepower while decreasing excess gasoline usage. It doesn't matter if you race or just take joy in driving a high-performance vehicle, the best quality auto parts are crucial. A vehicle's performance is a composite of several factors such as high quality parts. A well-maintained flex plate is intended to transmit force from the vehicle's transmission to the driveshaft simultaneously softening jitter from the suspension. The vehicle's flex plate is an essential part of your driveshaft. In the event that the car's flex plate is cracked or otherwise damaged, replacement of the old part will be absolutely essential before the vehicle can be driven. As the car's flex plate corrodes from exposure, the unit can become damaged and fail.
Automatic or manual, your transmission has to be connected to your engine to function. Part of that connection is made by the flex plate or flywheel plate. You need this part in good condition for smooth shifts and to operate your starting engine. Hearing clicks from near your engine, especially at idle? Fix your broken plate to take care of the problem and lengthen the lifespan of your transmission.
These plates are circular metal parts that mount to your crankshaft. They help operate the starter motor and contribute to balancing engine torque. You have a flywheel plate if your vehicle has a manual transmission. These heavy parts keep your crankshaft spinning so torque stays more constant during gearshifts. If you have an automatic transmission, you have a lighter flexible plate and an automatic torque converter that work together to do the same thing. An intact plate means a responsive and smooth gear shift.

What is a flex plate?
Your flex plate or flywheel plate is part of your vehicle's transmission. If you have a manual transmission, you have a flywheel. Automatics have flex plates. The two parts have a similar appearances and functions:
- They're circular with holes in the center and near the edge
- They have a toothed edge that looks like a gear
- They're part of the connection between your transmission and your engine
- The connect to the starter engine
In automatic transmissions, flex plates connect to a torque converter. They bend with different levels of force coming from your engine, allowing for smoother gear changes. These parts are generally lightweight since the automatic torque converter does some of the work that a heavier flywheel would do in a manual transmission.
Flex flywheels are much heavier. That's because the function of balancing the transmission during operation is much more important in a manual gearbox. There's no automatic torque converter to help out in a manual setup, so the weight of the flywheel levels out the changes in torque from your engine. This results in you having a smoother shifting experience.
How much is a replacement flex plate?
The flex plate or flywheel plate should cost somewhere in the region of $50-160, on average. Another thing to consider is that this is usually a difficult part to reach. That means you'll be spending a lot of time under the hood, so make sure to factor that time into your replacement budget.
How do you tell if you have a bad flex plate?
Unfortunately, this is a relatively difficult problem to diagnose. The most common problem is a knocking or clicking noise coming from your engine area. These noises are usually loudest while you're idling. That's due to the low pressure against the plate and the uneven flow of torque from the engine.
The definitive solution is to pull the flywheel plate from near your transmission and do a visual inspection. That's quite a job if it turns out your flex plate is fine. Check your maintenance manual: Some vehicles have a small opening where you can get a look at your plate. Otherwise, check the other culprits of engine clicking and tapping before you pull out your plates.
