Both ring gears are different in a 48re. Dodge made the sun shell thicker so they machined the ring gears on the thrust service and moved the direct drum groove higher. I'm upgrading a 47rh to all 48re. Big learning curve when trying to make 47 and 48 parts work. I have now updated every part possible. The one part you can not upgrade is the park pawl, pawl rod and overdrive ring gear. Those parts require a overdrive housing swap. Wish I could mill out for the rod but no idea what effect it would have. Anyone interested in doing a 47 to 48 upgrade you should first replace all hard parts then order a 48re rebuild kit so you get the fine spline clutchs.

it's not electrically shifted , like the RE models are

@chriscollier9251 7 месяцев назад

Is there a difference for PCM or TCM programming?? I have a 99 ram and I believe it had a 48RE Jasper in it when I bought it that was blown and I took it out and no longer have it. Should I put a 47RE or a 48RE back in it???

@CUTTERUPROB 7 месяцев назад

Pcm/ tcm in that truck is the same them. But you run can a 47re or a 48re. But i believe you have to change the electric stuff would have to be a 47re pre 2000 style. But I would talk with a trans guy to make sure

@hey_youtubeim_back2159 4 месяца назад

I was hoping you could help me with my dilemma. I have a 2003 Ram with the Cummins engine and a 47re verified by the VIN number. I purchased a 47re core from a 2001 Cummins truck and I'm wondering if the 2001 in the early 2003 47re are interchangeable ? Please keep in mind my 47re is a very early model in the 2003 trucks

@theinfamoussixcylinder3945 Год назад

Hey dude. I've got a built 47re and I want to but a 48re pump in it. What else do I have to change to make that happen

@CUTTERUPROB Год назад

Pump and housing. But you will like have to reshim on install

I'm confused by what you said my buddy rebuilt my transmission had to swap o.d housing mine was cracked but my big park rod won't fit I used a micro camera I'm assuming my pawl is ment for small rod so if I use the 47re rod it'll pop out of park?

@CUTTERUPROB Год назад

The 48re rod won’t fit in the 47re housing. The 47re rod doesn’t lock the the pawl the whole way.

@davidcovan607 Год назад

@CUTTERUP ROB so what do I do I have a 47re housing with the original pawl in it I don't think I can find a 48re pawl rod spring etc from the casing

@frankvottiero8704 3 месяца назад

Hello quick question what is the difference between RE-RHand Would a 48RE parts fit a 46RE

@CUTTERUPROB 3 месяца назад

Best to ask a trans guy on that. I know some parts that swap over. But not every thing that does or doesn’t

@torquewisdomgarage 2 года назад

Question: Does the 46RE,47RE,and 48RE have the same size case? Why I am asking is I have a 46RE behind a 5.2L. Was wondering if a guy could but 48RE internals into a 46RE case? If not what about the 47RE internals into the 46RE case? Eventually I want to make a 5.9L gas stroker(408). Just wondering how to ungrade my 46RE since it is the only case that will fit behind the V8's.

@CUTTERUPROB 2 года назад

the easy answer is no, but a alot of them you can use parts from

@darryladams519 2 года назад

@@CUTTERUPROB would the 48re bolt up to a 318 or 360?

@jimkillen1065 3 года назад

Many years ago a fellow form Canada told me that the front pump had more gpm from the larger gears . Its been a long time ago seem like 3.9 to 4.2 or some thing like that but the improved pump is a benifet

@CUTTERUPROB 3 года назад

the 47 to 48 pump the 48 pump does move more oil

@trevorhenry7339 3 года назад

I’m gonna be swapping my 4wd 5600 for a built auto FMVB, have a full 48re from a 06, 2wd though, have a 47 FMVB. Sounds like I should do a 48 swap and not build a 47?

@CUTTERUPROB 3 года назад

i would use the 48re if it was me for sure

@trevorhenry7339 3 года назад

@@CUTTERUPROB assuming my 47 FMVB will work? I noticed you didn’t go into many details on the VB differences so just wanna make sure before I pull that trigger.

@davidcovan607 Год назад

Are the 2wd tail housings the same with 47re and 48re

@CUTTERUPROB Год назад

Basically yes. Just make to to use the park rod that goes with the case

@user-fr5se9lf9r 5 месяцев назад

Output shaft is the same but the case bushing is bigger in the 48re. The yolks with not inter change on the drive line. I’d have to measure them but it’s about 1/4”

@elroyelblander6277 3 года назад

The front planetary ring gear of the gear train has the sun shell thickness difference removed as well...cuz the 48 is thicker obviously.. you'd have to measure it ,....those 47 sun shell sun gear hubs like to crack and twist off...hence the thicker 48 shell...but anyways...good stuff once again Rob👍

@CUTTERUPROB 3 года назад

i will do some measurements

@seanbrossard8178 Год назад

The sun gear were the c clips are are farther apart for the drum thickness difference

@CUTTERUPROB Год назад

Good info

@elroyelblander6277 3 года назад

👍👍The 47 pump is 11 lobe and 48 is 10 I believe, as well...

@CUTTERUPROB 3 года назад

i believe your right

@jimkillen1065 3 года назад

The aluminum carrier I think is in my 47 rh and I was told that they can fail so I don't shock load my transmission . I really like the way you machined the carriers to run bearings . I know that a 48 rh has been built but I bought a rebuilt a g 56 instead
