I have bought parts from power driven just because of this channel and how genuine you guys are! Keep up the good work

[@scmroman]

Can I get that paste at oreillys and if so what is it called.

[@horsetorquesdiesel]

We get ours from Napa. It’s called transmission assembly grease

[@Thedave2224]

This and powerdrivens videos hands down the best content on youtube.

Best video on KZbin for these transmissions. Good stuff guys

[@horsetorquesdiesel]

I really appreciate that!

[@lukestrasser]

Killer Job Josh and Meyer! Watched end to end, lots of great pointers, tips and tricks that apply to the 727, A518, and 46/7/8 series. Cheers guys, great work.

[@horsetorquesdiesel]

Thank you! Glad you liked it

[@lukestrasser]

Wanted to leave a comment for the algorithms, I already know the video is gonna rule. Will come back in an hour 20 to tell everyone why its amazing. Cheers!

[@horsetorquesdiesel]

Thank you!

[@peterf.4268]

I am nearly 50 years old. I have done quite a bit of wrenching in my life. I would pull a transmission, but I would NEVER work on one. Kudos, guys.

[@darrinsp]

This video is the most comprehensive with measurements tips and tricks I've seen on the WWW!! Josh, I Have a PDD low stall converter on it's way, Baron said you guys haven't broken one yet, testing will continue in my 07' Mega Cab, 6.7L Swap, 850HP, compound daily driver......

[@bdjm8595]

curious what kind of fuel economy you get with that setup?!?

[@travislyman2278]

And this is exactly why i love the transmission y’all built me. Keep up the good work.

[@justinreed1174]

Most definitely buy my next transmission for Power Driven Diesel

[@horsetorquesdiesel]

Awesome!

[@rowdykrowd435]

You should offer a rollerized service for those of us that want to build our own !

[@JamesArington-s7h]

Been building transmissions well over 35 years, you need to rethink using assembly lube in the pump. The viscosity of the lube you are using will cause the pump to self destruct, you are trying to squeeze jelly through the pump where fluid is made to go. Use a full synthetic engine oil it will mix with transmission fluid. It's a old trick when 618 came out to keep the OD planets together. We actually mixed 4 qts mobile one in the transmission fluid to help with the restrictions of the feed in output shaft before it got fixed by Dodge

[@bernhard8540]

Shoot I literally have accidentally deleted so many comments from myself instead of writing a reply on them haha❤ and youtube needs to quit unliking videos i rewatch videos a lot and have noticed that even though I like them. They are unliked.. either that or the app is just hot garbage and doesnt show me it's liked😂❤❤❤ ps we need to get mer to upload videos again, he does a good job like Josh at explaining stuff for those of us doing this stuff ourselves and either need a refresher or its their first time❤

[@KDrapsag]

Why and when do you use 2 large springs under second gear servo cover? I can’t make out what Meyer said.

[@mikestrucks]

Great video as usual ! You guys are killing it... awesome work 👍🏻

[@bdjm8595]

Excellent episode!!! Really confirmed again for me that I'll be having you guys rebuild my trans!! Yeah, I'm sure I could do it myself but why, you guys do it all the time and know all the tricks!!!

[@michaelchristopher9444]

This video is going to help alot I'm about ready to buy a rebuild kit for my 48re. Having trouble choosing one as everyone's kit varies so much. Just looking for a master rebuild kit. What are you thoughts?

[@horsetorquesdiesel]

I would recommend one of the kits from Power Driven Diesel, it includes everything that we used to build this one!

[@rodneyswearingen1020]

Didn't you learn not to use a claw hammer when driving against steel drivers?

[@MLGtroll365]

Can yall do mine lol 48re stock but i don't want stock anymore. Edit: Lol dude in gray hoodie is a lil rough on the parts man. I like nice n easy. Not tossing nd droppin parts in. Gently.

[@horsetorquesdiesel]

If it can’t handle a drop or rough handling it sure ain’t gonna handle what comes through the input shaft. 12000 miles on it and hitting boosted launches daily it is just fine.

[@nyertsenginetransmission3861]

Can tell he has done plenty of these! Thanks for the info

[@denverbuerge]

Love how you guys show and explain the whole process first to finish 👍 appreciate it

[@horsetorquesdiesel]

No problem!

[@georgepierce9253]

What makes the 2 to 3 short take so long? I did transport HD value body kits had vacuum tested then Idaho transmission warehouse change it and now burned up reverse band and drum rebuild it and now it's 40 mph and have to let off fuel pedal to shift. Any information to help thanks

[@MrTk6969]

Man you sure aren't giving those frictions anytime to suck up that oil I also liked how on the overdrive clutch pack there's dry spots all on the frictions you supposed to let them soak for about 10 minutes

[@simontaylor6718]

Hmm, yeah

[@usmcraid5332]

Some soak overnight even better

[@MrTk6969]

if you've got all night to soak them you can but they're not really going to soak up much more oil after about 5 to 10 minutes but just a quick dip like that you can see that oil gets absorbed so quickly and they are not fully saturated

[@walterinc6060]

I have a semi built 48RE , with 50k, has to come off the truck the rear main needs addressing , could you go thru it before I out in back , I also want to add a tap shift valve body

[@horsetorquesdiesel]

Absolutely Call the shop 276-608-3298

[@bernhard8540]

I know its older but i was rewatching some older videos again haha and idk if youll see this but i just am trying to find out if anything else vesides the governor pressure solenoid and transducer would make the 48re start out in what feels like 3rd gear..? My truck will not shift down into 1st or 2nd i know for sure, even manually putting it in 1st or 2nd it just stays in what i think is 3rd, i parked it til the parts i ordered get here but in the meantime im just trying to see if theres anything else that could cause this..?

[@horsetorquesdiesel]

It can be that but usually it’s no 12v power in

[@seanmccafferty2197]

Do y'all do this for 68rfe I've been 2 ats stage 3 the last one didn't last 2500 miles it over heats and locks into 4

[@horsetorquesdiesel]

Not yet but we sell WP development 68s

[@johnchapman6041]

I think the video was great. It made me NOT! want to jump into my 2000 5.9 Cummins transmission 😁. So I have a question. I bought my 2500 in 2000 new never used it for towing. It's got 141,490 miles on it. It sat for 10 years. I changed the fluids, not the transmission fluid but I did change the filter and 2 qt.of fluid. Now! When I start it cold put it in reverse, I have to wait about 30 sec. before the truck will move. After that it will be okay for the entire day. What Is wrong with the transmission and how long will it last? It's not a 4x4.

[@redhound2466]

Do y’all sell built 48re

[@daniastopjik3287]

What about it having a kinda violent clunk when going from reverse to drive and drive to reverse. Not like a mount or center support/u joints lift. More like a rotation clunk. Like a cla clunk..any ideas?

[@kennethbranscum2738]

Thank you so much for posting this. I have the ATSG book but this video is invaluable to me as my 48 will be the first Trans that I have tackled.

[@SDP_5.9]

how much hp can a factory transmission handle and what all do I need for like 700hp

[@horsetorquesdiesel]

Factory power, I’d do all the small billet parts, gpz clutches, billet input, triple disc converter, deep pan, built VB, and probably an output shaft if it’s 4x4

[@buckshot927tx]

Lol I wonder how many hate comments y’all got for using a claw hammer on a trans. Keyboard ase certified mechanics give y’all hell I know. Good job fellas. Thanks for all the good info. Keep it up.

Sorry to disappoint

[@Idahoprepper71]

I put the R Wreck🤔😂

[@Engine_biulds]

I would really like to see if you guys would test out fan based mods. Like a head ported (52-56hour port job) because I will never make the power you guys are shooting for. And I can get 4mm larger on the seat without going to a larger valve but going with a larger seat to help keep the seats "in". I think it would be cool to dedicate a truck to fan based upgrades and use it to raffle off or take to competitions

[@bernhard8540]

I remember the one time I did my first tranny swap I was 16, (now 36) I didn't know you should locate the torque converter bolts but luckily for me I over tighten everything by hand so they never came out haha but now I'm like you are I definitely help pay the light bill at the loctite factory haha❤❤

[@bigmurph1447]

Did you guys drill a whole in the back of the case to feed the lower sprag mom oil. Also on the direct drum you can use a flat snap ring out of a Chevy 350 trans to get more firmer shift

[@horsetorquesdiesel]

We did drill into the back. I’ll have to check that out!

[@kevinjohnson9372]

I believe u use the 350 case snap ring to get the extra clutch in the direct drum and there is a piece outta the forward drum that has to go into the direct drum I believe its the top plate or bottom plate that and the different snap ring let's u use another clutch and steel on there

[@bigmurph1447]

@@kevinjohnson9372 yep ur right

[@dontworryaboutit1]

@@bigmurph1447 this seems like gospel out of the centuries old Will Terry comp d write-up lol

[@claytonhaske]

But will the direct drum from a 48re fit the 727? Does this mean you can actually get 7 frictions into the drum with the 350 snap ring, and flipped pressure plate modification?

[@jimkillen1065]

I appreciate the video . The triple disc convertor do you use a stock stall speed , and do you also use a stock stall speed for some one who just wants to use the truck for towing and not racing .I really hate my stock transmission for towing and the pitiful fluid coupling with 3.54 gears . Thanks for any advice

[@oxidationnationcrustyrusty4498]

So I was debating doing my rebuild myself (for the first time) now after watching this I want nothing to do with inside my 48re... so if I want to buy this exact transmission you just built to put in my truck where do I go and what does it cost

[@bernhard8540]

I used chrome socket on an impact gun as well until on exploded and smacked my in the mouth and chipped my right from tooth. Now I paid for good impact sockets and a fixed front tooth haha. We all learn lessons after the fact haha ❤

[@RR-cv9tn]

What steps did you do to undercoat the truck? I want to freshen mine up but don't want to trap rust under the paint and make it worse. Truck just has very minimal surface rust.

[@TAShannon1]

I bought a project truck without a trans, its a 96 12 valve (Man i'll never buy somebody else's project ever again if i can help it). I bought a rebuilt nv4500 and clutch kit to go with it. Well one of the Crankshaft bolt hole threads is trashed. I ran the correct sized tap through it to clean it out and try to restore the threads but the new bolt couldn't get past 60ft lbs without stripping the female threads that i had just chased. Well i needed the truck on the road so she has 7 bolts in her instead of 8 until i can resolve the issue. It's been 4k miles since... I am at a loss though. Do i drill it out a fraction larger and try to retap it to a different spec? do I use a Heli-coil? I really dont know what would be acceptable here lol

[@horsetorquesdiesel]

Helicoil will do it just fine

[@colesanford8669]

Great video!!! we’re you running a 12bolt flex plate with a 6 bolt converter? If so why? And if you run a 12bolt flex with a 6 bolt converter would the holes line up with you going 1 bolt 1 hole then skip hole on the flex then again a 1bolt one hole method?

[@horsetorquesdiesel]

yes 6 bolt converter 12 bolt flex plate. Just skip one hole on the plate, works just fine!

[@Shalash87]

Excellent video! Out of interest, how much did it cost parts wise? Also, out of curiosity, you made a fully manual tranny. Is it possible to go for the full clutch n stick conversion? If yes, why opt for such a rebuild?

[@horsetorquesdiesel]

When at this power level the automatic holds the power much better!

[@BOSSArcticCat]

It looks as if a 48re just falls apart. For a guy thats use to rebuilding manual transmissions would it be hard to switch over to automatics?

Interested. Please provide deets Thanks

[@realmccoy9597]

Never assume that you have the right thrust washer on the pump until you check end play with a dial indicator! Don't install the clad seals or the pump seal for this measurement. The most forget problem with this transmission is that the spacer ring on the intermediate shaft is worn and everyone makes up for the difference on the top end! Putting your sealing rings on first on the pump is pretty cocky without dry setting the pump and not using a dial indicator.

[@jaredmayer3960]

it’s all out of respect for the bosses.

[@derekblackston4831]

You talk about using thicker/thinner steels and snap rings. If a guy is going to buy a kit and do this in their home shop where do you get the various thickness parts you need to maintain clearances?
