Flexplate - How Flexplates Work vs Flywheel

[@SummitRacing]

Thank you! If you have a question or video request, please let us know.

[@SummitRacing]

There are many variables that play a part in choosing the proper flexplate or flywheel combo. Things like camshaft, engine size, torque converter, transmission and the end use all play a part. Please give our tech department a call at 1-330-630-0240. Thanks for watching!

[@SummitRacing]

We have a few additional questions for you, do you mind giving our tech department a call at 1-330-630-0240? Thanks for watching!

[@tristanjeno4890]

I came in here to learn something and got an advertisement, lol.

[@SummitRacing]

Yes, that is correct. Automatic transmissions require a flexplate and standard/manual transmissions use a flywheel.

[@TheBrown8363]

Summit Racing can I put a flywheel in place of a flex plate on a 97 jeep grand cherokee 4.0 42re

[@candorguy]

Great Information!

[@larr5e]

Thanks for the info... It is promoting their products but also helped me (novice DIY car repairman) learn that a flexplate is automatic transmission while flywheel is manual transmission. ; )

[@otm646]

You use e coat because it's significantly cheaper, not because it offers superior anti corrosion performance. A zinc plated flex plate if properly baked out will perform identically in fatigue applications.

[@scottwade2995]

Upgrade to high performance 350. Old flywheel has center bolts at 3 1/2 inch apart.need one for 3 inch to fit back of new crankshaft.can I get one that's 14 1/3 inches in diameter so the starter will still work.video was helpful!!

[@Mensaje22]

gr8 work I'm a buy one of theses

[@SummitRacing]

Good question, this is common misconception that painting an engine or transmission black will make it operate at higher temperatures. Black paint does absorb heat more than other colors but this is only true when the heat is being generated by direct sunlight. In area's where there is not sunlight like the engine compartment and under the vehicle this is not a factor.

[@rock1957able]

I have a 2005 Nissan Altima 2.5 automatic. my starter is skipping during starting..i am told that I need a new flywheel. does my car use a flywheel or flexplate

[@sylvainlavoie276]

Do you have a Flex plate more stronger fore Dodge C/V 2014. The OEM crack every 5k miles

[@G_star45]

Can a flexplate cause shudder between 30 to 40 mph ?

[@Tony-tk4ht]

this is weird i am just now learning about this. always worked on manual trans. never really knew how torque converters worked

[@user-cf6ys7kh6g]

Good but ,what's the difference between the salid &star looking kind ?

[@andrewvillella2]

so i can put in a flex plate or a flywheel?

[@tonyjara184]

Love you voice btw.

[@jackkarie5281]

@Summit Racing I am looking at possibly replacing my Flexplate. How much is it supposed to flex? I can bend it by prying lightly around the edge with a screw driver from the inspection cover area. i can also push it in with one finger. It appears to be much thinner than TCI brand flexwheels. it is also hitting the bolts around the crankshaft which leads me to believe it is cracked.

[@SummitRacing]

+Jack Karie, Agreed, if you can push it with your finger, it is most likely cracked and in need of replacement.

[@jackkarie5281]

I called your customer support number (as mentioned in one of your posts). I couldn't have spoken to a more rude person. The fellow on the phone was completely impatient to answer my question. My question never completely made it through without a specific answer before the phone call ended. However, I purchased another engine (I had a bad engine bearing) and the flexplate flexed just as much as the previous. This is on a 2004 Dodge Caravan 3.3L engine, not a race car by the way.

It's like she's on a elevator and she quickly goes up a floor before the ending of each sentence. Perhaps it's a gesture for interpreting the flex plate motion dynamics in the form of contrived vocal buoyant resilience. you ignite me ;) 0:56

If I don't have torque converter bolted to flexplate will starter labor more

[@HideTheTruthInside]

Got a ?....I need a flexplate for an automatic transmission in a 2000 Dodge Durango w/ a 5.9 V8. Parts stores I have talked to sell the flexplate without the ring gear attached. I can't seem to understand why anyone(including me) would want a flexplate without the gear(teeth) attached. Any thoughts?

[@SummitRacing]

Steve B , The starter ring gear is part of the torque converter in Dodge applications.

[@kodycameronrich]

where can i buy on for a 95 ford mustang flex plate.

[@SummitRacing]

Hi Kody, Can you give us a call on our tech line at 1-330-630-0240? We have a few questions regarding your engine before we can help. Thanks!

[@beardedparanormalresearchg8543]

I have a question I bought a 3/4 ton GMC that had a motor swap the flexplate is cracked now but the person I bought it from doesn't know what vehicle the motor or trans came out of how to I insure I get the proper flexplate for my application? any advice would be greatly appreciated!

[@SummitRacing]

Hi Bearded, We need some additional information from you. Can you give our tech line a call? 1-330-630-0240. Thanks for watching!

[@jhondoe2473]

Look on the engine their is mostly a code

[@gladysknight6462]

Flexplate on Jeep Cherokee makes occasional noise, does wheel alignment, larger tires or 2"-4" lift affect performance and/or create noise?

[@SummitRacing]

+gladys knight, If you are certain that the flexplate is making noise. You should investigate further and replace if necessary. Could larger tires affect this? Yes! Those larger tires put more stress on the drivetrain as a whole.

[@mamaangela78]

Hello. I was wondering if their is more then one flex plate in my 2013 dodge journey?

[@jeromeygreen4788]

No, there is only one flex plate in an automatic transmission vehicle

[@bigchrisrogers]

Puzzled. If the amount of flexing is important, to take up axial movement in the crank and/or the torque converter, then surely a much thicker, machined flexplate will have a different amount of flexing and perhaps give durability problems elsewhere?

[@SummitRacing]

The thicker flexplate with increased rigidity and durability is required for high-performance applications with increased rpm capability and higher stall converters and to meet SFI standards for safety rules. The machined flexplate is not for most stock to mild applications. There won't be any problems when you're using the correct flexplate for the proper application.

[@mikemccarthy6407]

Can you explain how a torque converter "grows" as RPM increases such that a flexplate needs to flex? I just don't get it.....how does increasing fluid pressure inside the torque converter make "flexing" necessary?

[@SummitRacing]

Hi Mike McCarthy, The Torque Converter body itself is not supposed to grow, but due to the transmission fluid pump pushing fluid into it (under pressure) and its internal operation with increasing engine speed (also creating pressure) propelling the vehicle, the converter must be allowed to float back and forth on the input shaft of the transmission. This is a minute distance but we must also consider some crankshaft endplay as well.

[@mikemcking]

Thanks.....

[@privategramcracker01]

So does the flexplate also work as a flywheel in the sense to keep the crank shaft's rotational inertia?

[@Trident_Euclid]

The Litterbug Almost. Now it's mostly handled by the torque converter.

[@1997LT1Camaro]

All rotating mass is to be considered when balancing. The flex plate is much thinner than a fly wheel, so sometimes they balance with weights on the torque converter.

[@erikhyde7625]

When you say “mild-medium street applications” and “high performance”…. What horsepower level are we talking.? I’m going to be pushing about 850hp through a 1988 s10. What would that be considered?

[@tonny.c]

Every other sentence is finished off with an 'unhhm'. Summit racing california influencer special narration :D

[@lildragonzfu]

So you are telling me that on automatic transmissions they use a flexplate instead of a flywheel clutch plate like they do in manual transmissions

[@supermansavez]

How does it bend if there are bolts holding in place? Is that why they are breaking?

[@dntlss]

Actually run of the mill flexplates are relatively thin so they will flex some,more on the outside of the circumference than in the middle where they are bolted,think about it like a old trash can metal lid, bolt it in the middle but you can still move the outside metal around if you pull on it,i had one in a engine on one of my cars for 25 years, when i replaced the engine that flexplate was in excellent shape and it had been "flexing" all that time,guess if your not pounding on it all the time they will last a long time. I actually had a engine built and my builder sent me a scat flexplate like they show in the thumbnail for the video and i never liked it so i went with a OEM one , reason i didn't like it its because as a SFI aproved fleplate (high horsepower certification) it was made extremely thick, i dont think the Queen Mary sitting on it would have been able to bend it any so that right there didn't inspire much confidence and i had heard of broken teeth on these also so i just didn't use it.

[@giovannimazzocco4788]

There's a flexplate better then original 62te fore doge journey? Can you send me the link where buy it? Thank you

[@Radiator1991]

I listened your phone operators on the type of Torque Converter I needed for my 383 Stroker with TCI flex plate and you guys sent me the wrong one and are charging me for shipment... Ill never buy from Summit again

[@nainarkumar]

I want know is available for manual transmission

[@cheath8705]

+Kumar Nainar You will need a flywheel not a flexplate. For some cars, there are options of going to different weight of flywheel. For example, 1995 Honda Civic with 1.5L engine and manual transmission, there is a 15lb (stock), 11lb, 7lb. 15lb is easier to take off from dead stop than the 7lb but the 7lb has much less inertia, allowing to speed up quicker. How much quicker, I don't know. I haven't tried it. That is what I recall when I was researching. I don't have the car anymore though.

[@0ooWARRIORoo0]

I have a chvy express 2012 cargo van, and it breaks the flexwheel every 6 to 8 moths i have change 4 or 6 times already my mechanic its going crazy and he can't explain what causes this. He has done anything in his power to prevent this and keeps happening. Is this a common problem on this cargo vans? Im selling this thing im done!

[@Snailmailtrucker]

I'd put a 1/8 in washer/spacer on the Flexplate bolt to draw the nose of the Torque Converter back toward the transmission... sounds like the nose of the torque Converter is up against the Crankshaft.

[@alexanderjones2371]

If I had the wrong flexplate would it cause my engine not to spark?

[@joshuamoore24_7]

They need to make V-6 and Inline 4 cylinder flex plates that are billet also, and thicker than OEM!!!!!😁

[@Xander081987]

But why?

[@utuber4841]

ATS needs to make four and six cylinder flexplates, not just V8 flexplates.

[@hotrodkimbla]

doesnt the black paint make the transmission run hot

[@Snailmailtrucker]

I have a 1982 Chevy 350 cu. in. engine in my old Cube Van. I just swapped the original TH400 trans. to a 1991 Chevy 700R4 transmisssion. Is there a difference in the Flexplate that was on the engine for the TH400... and one I should be using for my newer 700R4 ? Thanks in advance ! *LET'S GO BRANDON !*

[@kennethcastonguay4635]

I don't know why there are 2 sets of teeth on This maxima v-6 flexplate

[@robbedoes1985]

They paint engines and gearboxes black because it emits infra-red radiation energy better then other colors, also when it is matte or wrinkle finished, the emitting surface it bigger. A flywheel does not create heat so there is nothing to emit. Internal friction makes transmissions run hot.
