Diesel Transmission Torque Converters | Power Driven Diesel 

The Intro of the year. When your co-anchor backs up outta shot you know its a good one.

Will’s face when he realizes he said “fat shafts” all excited. Priceless.

Very informative. I would recommend a Torque Converters Part 2, with another cutaway which explains the function of the fans inside as well as how lock up works. Good job guys.

Great video as usual guys. Appreciated the breakdown of pro/con between the 3 & 4 disc converters.

Getting a look inside these things it makes a ton more sense than it did before, more discs means more traction between the engine and trans. Has anyone ever tried to make a rebuildable torque converter? It seems like there could be a market for it in the performance world.

Nice break down on coverters. Intro was the best part!!$$.. Need to order a converter from you guys next week!

Very helpful. Thanks for clarifying the difference from a triple disk vs. a quad disk torque converter. Great job.

Yes another great video. I wish I would have known all this 4 years ago when I bought my Purplelish blue trans. I would have done it right the first time. Now I am soon driving to Denver to get it upgraded. looking forward to seeing you guys at UCC hope you do well there.

Excellent explanation. I am confident in my converter choice now. Thanks a million!

excellent explanation of how a lockup torque converter works.

Another awesome video from you guys 👍👍👍

Great content! Alot of great knowledge in this vid.

Will Gone Wild !!! Awesome. Great video. Informative. And Fun too!!

That intro was *AWESOME!!!!!*

Excellent video and info. Thanks for sharing.

I talked Power Driven tech support today and they quickly lined me up with the very best torque converter for me 2nd gen Cummings. I said ok you are the only one that understood what I was trying to do How much is it? When they told me the cost I was amazed it was so reasonably priced. The shipping was only $50 but if I paid the core charge ahead until I received the converter and return label then there was free shipping. Thanks, guys I think you are awesome

A episode about manual transmissions would be good. Clutches etc 👍🏼

Lots of good info guys great job

On point. New to CTD. Subscribing.

Great intro! I have your DPC triple and it's wonderful.

Great video guys. I know a little more now.🤗

Wow keep Will off the Red Bull 😂😂😂 great video guy's 😎. I would like to see more about the rest of the transmission and what you put into your built-up one's and the different levels of build you offer

awesome info. great job!

I could be wrong, but I think it is more PSI being applied to through clutches than the fluid pressure being created. Let's assume your clutch ring is 10" in diameter and 1" wide. Circumference is 31.42". Multiply that times the width and you have 31.42 square inches of surface. The 90 PSI in your example would be applied to each square inch of clutch material. That's 2826 pounds of force being applied through the clutches to the rear plate. Again, good chance I'm completely wrong here.

the lockup clutch is unlocked by line pressure fyi meaning the lockup clutch is always locked and line pressure is used to keep it unlocked. great info guys

Thanks for clearing up on how torque converters work. I've been a gearhead since I was 10 generally understand how cars and engines work, but torque converters always been my achilles heel. This video has cleared up some of that fog. Thanks PowerDrivenDiesel. And that intro is lit i LOLED so hard. THANKS again.

Thanks answered my stall questions, I was ready to get into more mods on my 98 dodge dually, a little set back truck was hit and totaled while parked, so I'm starting over, looking for a complete dana 80 with disc brakes on rear? And a truck bed.

Excellent!

WELCOME TOO POWER DRIVEN DIESEL !!!!!

Looking forward to a TC specialist talk about the details on the internals!

great video guys, but I have to say my past truck had a bad case of slushbox without much extra power, and it just pushed me to a NV5600 truck instead.

This was really helpful I'm trying to figure out what I will do with my 97 7.3 because something is slipping since my buddy plowed with it in November (I bought it as a plow truck in 15 and have put 100k on it plowed and everything was great till it was borrowed now slipping bad) trying to figure out what I'll do with it since I pull with it and everything else imaginable with it too

Absolutely cool video guys....😎 haha 😬👍

Great technical topic on torque converters in general. And thanks for explaining the quad disk topic. What about a video featuring the differences between an auto valvebody and a FMVB (full manual valve body)? What steps are taken to perform this upgrade? Is it a garage mechanic task or too involved and should be conducted by a transmission builder?

What would recommend for someone who is planning on building their transmission first and then adding a compound setup and possibly a 33% over pump to a 6.7 which will be used for towing and cruising? Saving up until you all have the transmission kits available for the 68RFE.

Since your in the trans,converter, how about the gear ratios to put this in full Perspective

Generally speaking, is it the TC or the transmission itself where the rated HP and TQ limits are created? I know mine (1992 M939 military 5Ton) is limited to about 700ft/lb, Cummins 8.3 engine with an Allison close ratio trans. Thanks for that video, but now it just made me ask more questions that I hadn’t thought of before lol

I am wanting to learn about transmissions but this went over my head. Any recommendations.

I would liked u cover a518 also

I like to see a video on the stator designs

The pump makes the pressure nit the valve body the valve body only regulates the line pressure and activities the solenoids to shift gears through the multiple oil galleries

I want to know it all. What does a 48re taste different than a 47re? Keep it up guys.

Talk about the different types of shafts out there.

So you guys got me sold on an 850hp 48re for my 06, my power goal is 600hp with compounds (s475 over stock) sounds like I would be best off with an 1800 rpm stall/triple disk for daily driving and occasional towing?

From my experience, single disc converters lockup harder harsher than a triple disc which locks up smoother and is more pleasant to drive

I’m doing a 24v swap with your budget build Cam in it, in my 98 6.5 with a 4L80E behind it. is my converter and trans ok ? It’s a daily driver / some towing

I know the feeling to many energy drinks 🤣

this is good to know. i got fucked over on a tripple disk i bought from Cascade - it blew up and took my trans with it. turns out it was a double disk with ford parts and NOT a true tripple. now i find myself with no truck and having to buy a new converter/pump/clutches/and maybe VB. for anyone out there looking to upgrade, make sure you do your home work and buy from reputable companies.

My 01 5.9 24 valve is turned up a little for performance i don't pull any loads. I'm installing a jasper 47RE with there triple disc. Will my trans temp run cooler as apposed to a single disc.

So quick question about a stock converter. Under hard throttle acceleration on a stock 2wd 2005 5.9 my tranny is slipping . Is that the torque converter? Also noticed that the pressure on my foot on the brake at a light is harder than usual to keep the truck from creeping forward at a light.

Stock Dodge Ram 2500 4x4 automatic w/4.56 gears So 1800 stall would work even pulling 35ft goose Please advise

Quick question, when are you guys going to re-do the turbo school videos cause the information in those is to good to not re-do.

Do you guys sell a rebuild kit and converter for a do it yourself kinda guy?

I have a 01 2500 4x4 Cummins with a 47RE Tranny. Its about done with. I bought a 47RE out of a 00 2500 4x4 with a V10 gas motor. The Tranny was to have 16000 miles on Rebuild for pulling.. I was going to put the Tranny in my Diesel truck. but was told I have too change the V10 Torque Convert and VB !!! Will Torque Convertor out of the V10 work ok or not. I just cant find the right answer.Thanks

ExFedex 96 truck, 59 12v, AT545n transmission single neutral no od, city gears, max freeway speed 68mph flatland, downhill a little faster. ;) Not looking to change transmission. What would it need to handle 500hp and do more than 68mph. P.S. Speed limiter is unplugged. When it was connected 62mph was the fastest flatland speed.

can the people of the community or maybe you guys at powerdrivendiesel give me a hand I bought a 96 that was stuck in 1st gear it had a rebuilt in 06 47re I bought a trans from a 00 24v it had on the bell housing a 48re but bolted up fine and I switched over my plugs and valve body and I daily drive it the beginning saying it wont work wat do you think is going on in mine then is there conversions people do or is the casings just cores for 47-48

Need help with my transmission leak right in front between the engine were the fliwell is

I am looking at a 2006 dodge 3/4 ton for mostly daily driving on the highway. I plan to do small improvements in power aimed mostly at fuel efficiency but also to tow a horse trailer occasionally. Cold air, exhaust, clutch fan delete, and a smarty type tuner. My goal is about 400 horse/800 torque. I plan to do a valve body and torque converter on a stock transmission. Should I stick with factory stall or should I go a little tighter?

Have you guys ever done methanol injection? That would be an interesting topic for a video

Do a video on your dailys!

Great info guys! I always feel like my stock '05 is gutless till lockup in 3rd gear and it starts getting the power down, now I know why. Is there a reason to not go with a 3 disc over a single disc converter at low power levels like you talked about with the quad disc vs 3 disc?

I not a expert on automatics transmissions in dodge , I don't care for mine in my old low power 12 valve . I can give it full throttle and the engine will go to 3000 or a bit more and never drop one bit till lock up . What a piece of crap . I think there is 750 rpms between each gear change . I really like power shift equipment , like in Cat dozers . I remember back when some folks were saying the single disc was as strong as a triple lol those were the days lol . Thanks for the videos

i have a 93 d350. Im switching to a 47RH and was considering your "pan off" upgrade. do you think that would be sufficient seeing that I'm only making 300ish hp? or should i also consider a converter? Also id like to see an entire video of Will talking like a WWE star. it was absolutely hilarious.

You can use a v10 converter on your cummins, but beware of a cummins convertor on a v10. A high profile transmission shop.."MONSTER TRANSMISSION " sold me a triple disc thor convertor for my 98 v10 truck. It went in and bolted up. I noticed once the bell housing bolts were in all the way it was hard to rotate the flywheel. And yes the converter was locked all the way in.. i called monster and they advised me that the billet case was a tad bigger than stock but it would be ok.. i started it up and the truck wouldn't move and was making a terrible noise. I shut it off and pulled it out only to find the the converter cut a groove in the stator housing and filled the transmission with ground metal. I called monster and they told me to send the whole transmission to them. So I did. Bob the builder..no pun intended told me that he replaced the pump and cleaned it all up and tried it out and that it would be good now... wrong.. i got it back 4 months later and it looked like it was never touched..i pulled the pump apart and it never was touched..i paid 1500 for that convertor and monster won't take it back and I've never been able to drive with it. Long story short..v10 convertors have a tiny bit smaller chamfered hole in the end of a crankshaft than a cummins. The hub is different on those converters. The cummins is a non milled flat hub, buyer beware

I looked on your guys site and didn’t see any built 68rfe trans kits/combos. Who would You guys suggest going with ? I been looking at ATS since I had their 5 disk converter in my old 02 Cummins 47RE. Very bad ass converter , but their 68RFE are very expensive. I have that 2012 Cummins 4x4 with a 6 inch BDS Lift turning 37’s, as seen in my profile picture. It’s my daily driver and I tow skid steers, ect...with it now and then. I estimate 475 HP with my injectors and H&S tuner on tow setting along with a couple other little mods. I plan on eventually making around 600-800 HP at most in the future but need a 68RFE that will take that torque and power with out a problem. Would You guys take on a 68RFE build ?

Why is where a core charge? If the new converter is new and billet.

That's how you do an intro!

How well do the dual disc converters hold?

Well I noticed you have not responded to any comments here but asked for them. Ideas anyone I have a 97 2500 4x4 4re. Just rebuilt and added some better internals to the transmission like the steel 6 gear sun gear and billit shaft with shift kit and pump upgrade. Went to 727 Kevlar overdrive band. And GM solenoid upgrade. Now trying to figure out which torque converter to go with. I want to build my truck for better pull with the best fuel economy. So looking to end up with 400 to 550 hp and more importantly 700 to under 1000 fp torque looking at converters with stall speeds starting between 1300 to 1500. I think I want to go to sequential twin turbos. I don't want to go with larger injectors just want to get the best dependable performance out of my truck with out having to watch the EGT's while towing. I have been advised to go with the 400s twin setup. I do have the copilot transmission controller. I have a 4" exhaust straight pipe looking for a intake upgrade now. And fuel plate. Governor spring.

Hopefully y'all can answer this. So stall speed has no effect on power output when the converter is locked?

CAN UGUYS RECOMMEND WHAT TO DO WITH THE FACTORY TRANSFER CASE TO MAKE IT STRONGER up graded trans triple disc converter forged shafts when I get on it now the chain jumps teeth in transfer case.

So what do you think Dodge is putting in their new truck with 1000 ft-lbs of torque? Just curious.

I'm a transmission idiot. What about a A727 3 speed cranking about 275-325hp 12v. I hear about upgrading flex plate. Just want a good all around converter/ plate to handle the power and be reliable for years to come.

Do you work on duramax/Allison transmission? I have shutter at 5 mph.

On a 48 when do you recommend the converter to lock when just daily driving it?

How tuff is it to rebuild a r 48 out of a 04 dodge and are the aluminium driveshafts as good as the hype. 😀

Living in GER I/we usually do not drive automatic - if "so" it is a double clutch. Therefore stall speed was always a little hard to understand. Great explanation! But still: Your videos are underexposed > too dark. I think ~ 1 stop. = next time exposure compensation up +1. Obviously your automatic setup is too dark.

🚨👉👍

48re is the shiz! Lol!

They way I take it is never use a single disc behind a cummins

Auto trans aside..... Why no manual transmission option?

You had me at fat shaft ......... 😐

I sense a little "friction" between these hosts

No! Soon as the turbo starts to spool the Duallies start to smokin!

I have a 6spd so I don’t have these problems 😂

first comment #4btrangerswapftw

V10. Lol

Did Will edit this video? He seems like he’d be the type to make that annoying intro.
