I have zero need for a built 4spd, but I can’t stop watching!

[@wellshodgarage2752]

I welded the forwards together last week in my one truck. You just answered my question. Thank you seriously

[@BrockwRock]

This is the best 48re video I’ve ever watched. I’m super impressed. I wish you guys were closer to Vegas.

[@tybrownsr.4466]

It's so awesome that you're using gloves, so that chemicals don't enter your bloodstream through your hands and damage your internal organs. Smart man!

[@Nathang2233]

Heard some shops went back to using the wavy snap ring in the overdrive on 06-07 48re with the Tva motors, because no wavy snap ring can cause a harsh downshift in tow haul. Firepunk guys are the best. Very helpful videos

[@TheProchargedmopar]

That's what Performance Trans says in Amarillo.

[@madison69]

I honestly have not run into this issue yet, just finished a 07 48re the other day, we never use Wavys here, and have never had the harsh downshift issue unless it's one of our race transmissions

[@brianb5779]

​@madison69 For a street/strip build (mainly street) would you recommend wavy or non-wavy? Thanks in advance. Im doing a 727

[@Okie-Tom]

Would this be doable by a diy’er that has never worked in transmissions? If so, what special tools would one need? Tom

[@kalaniyoso5654]

Wow by far the BEST build video yet to date anywhere!!!!! I’m a diy guy from Hawaii and I just learned why my home built 46re with 48re internals behave the way it does…. I made it everything on the tight side… gonna order a new kit from you and rebuild soon. Thank you 🙏

[@DR_Hopegood]

Excellent presentation. Will be calling you in the future. Got a 47re that I’ll rebuild soon. Thanks.

[@mikestrucks]

Awesome video guys ! I do like the borg Warner band as well best band for the price 👍🏻

[@bernhard8540]

Idk if its working in the oilfield for so long or whst but i always start my trucks up and let them just run for a little bit just to let oil circulate and etc it never hurts to let it run for a few minutes before you jump in and go it really can save the life of stuff

[@bigmurph1447]

You should try and put every part on the 47re and 48re on yr web site. Those selective spacers and the snap rings on the intermediate shaft are hard to find I would like to buy a few of every size.

[@Fullerperformance01]

Moparpartsgiant.com has the selective spacers. The snap rings are discontinued. I buy the same size from McMaster Carr.

[@brianb5779]

Anyone know how thick the pressure plate is after machining? I did mine and was curious how thick/thin they go.

[@twintibbsdiesel93]

You guys are just Amazing ! I'm saving money to afford a 48 swap in my 2008 Ram 3500 rear wheel drive . I need your guys 48 I'm only going to run 1k horse power so your 48 will run perfect for my rear wheel drive dually :)

[@Bonkers49ner]

Great info, thank you for taking time to spread some knowledge Lavon!!

[@Moose400ex]

I'd almost say it would be best to just replace coolers! Stock oe coolers are garbage that have the thermostat in them. The stock oe trans cooler lines are small and tiny. Delete any heater changer, replace the factory oe cooler with a nice mishi motor cooler that's twice at big and twice and thick. Upgrade the trans cooler lines and go with the fleece perf trans cooler line kit! 1/2" flexible high pressure trans lines with AN fittings. Bigger trans cooler lines and a bigger trans cooler is another way to get more fluid capacity! Just between the bigger lines and the bigger cooler that's prolly an extra 2 quarts alone. Bigger pans add an additional 4 quarts. A secondary cooler mounted up under the bed with fans blowing on it for heavy towing.

[@bobbymoody7]

It's a great master rebuild kit! Thats what in my 47re fmvb!

[@jakobcurtis9751]

been doing locked 2-3 shifts everyday on my 47re for like 6 months. guess i’ll stop doing that now lol. i’ll be replacing my 2nd gear band sooner than i thought

[@bandabanderos]

I just learned a quick hack to installing a trans brake without any effort lol On a side note, would too loose a forward clutch result in a trans not going in lot gear? Recently my home built 47re started doing this thing where you start it, put it into forward gear, and usually nothing happens. If you rev in park or neutral to 3500rpm for a few seconds, it goes into gear fine. Doesn’t happen nearly as often once trans is up to temp. Also it goes fine into reverse all the time.

[@bryanancy]

Great video and thanks for the great information. Now I know why my recently rebuilt trans has drain back and my possible overheating issue. Thanks again.

[@greendodge98]

Great job Lavon

[@calebjackson2631]

Very informative video. I appreciate the effort and time put in. Thanks!

[@brianb5779]

Any tips on installing piston w bigger lip? I had to use spring Compressor to get it to go down.

[@pbAdpcustoms]

Can you call and order selective snap rings when you rebuild kit

[@DieselRamcharger]

excellent info right here! big props for taking your time to put this info out into the world my man.

[@denverbuerge]

Love the tech advice thru video. Learn a lot. Thanks

[@booostdemongarage4827]

I’m not the type of person to put this but ,sign the rpm act before it to late. We can’t let the epa win

[@wraithsrath7310]

Just a quick question I have a 46re can I use the 47re master kit to rebuild it a little beefier. I have already used the heavier parts when I had to replace my forward band because the band strut wedge failed. I know some of the hard parts differ but if I can add a little strength during rebuild would be great.

[@alfredorhs]

thank you man for that information and you time, i appreciate....

[@TunaCat929]

I’ve recently been getting stuck on inclines while towing occasionally. I think it might be when the transmission is really hot and overworked? But it almost feels like the brakes are stuck then there is a loud clunk that I can actually feel and it finally goes. What do you think is happening/failing? Thank you!

[@savagefabrication795]

Awesome video.

[@bernhard8540]

Bought a early 04 2500 and it moves in drive but barely and its as if it's in drive or 3rd and reverse is perfect and all gears show perfectly on dash but when I manually put it in 1st or 2nd it doesn't make any sound and it doesn't feel as if it's shifting into the two low gears... im gonna pull it and go through it but just before I bought it it qas rebuilt to some degree because it's stamped with the rebuild date.. hoping it's governor pressure solenoid but my luck the forward is cooked.

[@FirepunkDiesel]

Put truck in Nuetral then quickly slam the shifter into manual 1st and see 8f it takes off in 1st, if so it's governor pressure solenoid or transducer

[@wild12valve]

So I have 47rh, will the 48re planetarys directly swap in?

[@scmroman]

If I buy the competition kit and rebuild my 48re how much horsepower could I put through it without turning it into a grenade?

[@jeramywrestler7094]

What is a locked 2-3 shift and how do I not do that 😂 buying a comp 1 don’t want to mess anything up

[@sixinarow6.753]

I have a g56 truck, but here I am, learning the 4 speed. lol

[@samaltman8901]

Off too the garage to build my 47 now

[@daviddroescher]

Is there a way to use the OD as a gear spliter /conventional brownie? Aka 2nd over.

[@josephvanderdoes9813]

Good afternoon I have a question for you guys I am having a issue with my 2006 Dodge ram 2500 diesel with the 48RE the issue that I’m having is the little square box that surrounds the park neutral reverse drive flickers and The truck loses power for a second or two and comes right back to life it does it when the truck is warm I’ve rebuilt the valve body in the transmission I’ve change the shift cable and the neutral safety/rain sensor 3 times I’ve made sure the tipm connections are cleaned the battery terminals are clean have you guys had any issues like that and what have you done to fix it thank you in advance

[@codyvanmeter4583]

Mad props great video and great explanation.

[@austinwhite8364]

How are y’all doing considering the new crack downs with the epa y’all are a bigger diesel business and there hitting the small ones hard just wanted to see yalls approach against that or if y’all don’t have any restrictions ?

[@127rider]

My transmission started to shake when shifting from 1st to second gear, checked the band and did service the oil + adjust the band, nothing has changed, it only shakes when shifting 1st to 2nd, any of you guys have an idea? also the trans has 40k on it since complete rebuild, oh also ive changed the governor selenoid too

[@bigpoppasjunk333]

Do you make this kind of kit for the 68rfe??

[@1818saul]

Thanks for such a great video!

[@trentgiovanelli8602]

What's the recommended valve body for a street/tow setup?

[@dpgoverride]

I have exactly .020 but its tight in a few spots, can't get .021 in unless I press on the pack a little to assist. Should I go ahead and change the selective snap ring to add a little bit of clearance?

[@FirepunkDiesel]

020 input shaft end play is tight, I'd get it to 030 if at all possible

[@dpgoverride]

@@FirepunkDiesel My apologies, I should of been more specific as to what I was referring too. The fwd clutch pack tolerance, as said in the video set to .020 or as long as clutches spin freely by hand, ATSG manual calls for .025....I shaved a bit off the snap ring and was able to tightly fit .025 in, realistically probably closer to .023.

[@darrylpenman324]

Great video

[@eclifton4070]

Building a Fummins. Do you guys rebuild the Allison 6spd? Looking for around 8-900 hp 6.7 when done.

[@Steve_I]

There are a few reputable allison builders, but Look up Dimitri millard if you want arguably the best.

[@Ashroyer86]

Which cummins did you mate it to?

[@ernestoluzan]

@firepunk. I have 07 5.9 with 48RE. 3.73 gears and currently running 315’s for tires. I need to replace my tires this year, and am shopping new 315’s or 35’s. Are these tires going to be trouble for my transmission?

[@FirepunkDiesel]

The heavier/bigger tires will definitely put more load on the trans but a 3.73 and 35 can survive if you drive with common sense

[@ernestoluzan]

@@FirepunkDiesel ok. I tow a 10k toy hauler but I don’t drive like an a$$hole, so I hope it’s ok

[@Mopargocar]

Do you scuff up your steels some before putting them in with the clutch's?

[@FirepunkDiesel]

No we don't, we will figure 8 scuff the direct drum if it's glazed but we used to do every steel but after some long term (100k mile) comparisons, we saw no real world difference in clutch wear

[@bernhard8540]

I am very suprised with all the money there is to be had in 48re transmissions that nobody has tried to manufacture cases and vb... i mean theres plenty of companies making billet engine blocks and etc but if just one of them spent the money on engineering the 48re case they could make it better and they would easily make their money back in no time id gladly buy a whole new case and vb just to know im stsrting with brand new parts.. i get that it would take a good amount of monry and time but it would pay extremely well i mean its not just dodge guys/girls that would buy them but also other brand vehicles that have cummins engines in them.. and i mean someone thst knows what they are doing not overseas but here just like the engine blocks are being manufactured ❤❤❤

[@ryanalbright1143]

Are you going to have a kit on your website that would be able to hold up to 1000 hp engine?

[@FirepunkDiesel]

this master kit is what we use for all our big power builds, add a good valve body, and billet shafts/converter and you'll be ready to rock

[@dwight072]

Best in the business 🤘🏻🤘🏻

[@joesalazar770]

If you could why not machine a case from billet or maybe something even tougher or make a bushing from machined steel and it won't wear just a thought pros and cons to all things. 😀👍

[@williamcoker9873]

Build any AS69RC to hold 600-800 hp?

[@FirepunkDiesel]

We have a few in progress currently

[@Engine_biulds]

You say the billet bands tear up the direct drum but I beg to differ The stock bands do far worse damage than a billet you can actually reuse a drum that was damage by a billet band wear as you literally junk a drum that was damaged from a rivet gouging groves into the drum. You should expand on this topic if you actually have enough experience with these billet bands

[@Engine_biulds]

The billet bands are atheist far more precise and literally fit the drum perfectly the extra wide band that is 3/16 wider is the only band I use anymore. I don't believe the older borg band will hold what a wider billet band can hold I seriously doubt it

[@talonsheek3593]

How much horsepower is the master kit good for?

[@FirepunkDiesel]

The master kit can hold 2000hp when you add the correct billet shafts, valve body pressure and converter combo

[@talonsheek3593]

@@FirepunkDiesel okay from all that’s included in the kit what can be anticipated?

[@FirepunkDiesel]

@@talonsheek3593 about a 15% increase in clutch surface area over stock, I would add a valve body and it will hold 450-500hp with the weakest link being the stock input shaft

[@talonsheek3593]

@@FirepunkDiesel okay that’s good to know. Provided the horse power is under 500, what could the transmission safely handle? Burnouts, boosted launches, racing etc?

Would be a crazy build

Had to replace 3 overdrive cases within 2 years, damn expensive proposition, especially when you have a tranny shop do it twice. I'm starting to question the reliability of the shop!
