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.
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
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
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 🙏
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 :)
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.
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!
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
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
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.
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
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 ?
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
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!
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.
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
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 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.
@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?
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. 😀👍
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 ❤❤❤
@@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
@@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?
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
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
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!
Who's going to step up and start casting new cases? I thought somebody was going to start selling beefed up new cases but never heard of anybody using them.
