Hi Everyone,

Newbie here at posting but have been a member since 2015. I tried and tried for a search and have found a lot of answers but still need some more.

I am in the process of a 4x4 conversion on the truck in my sig by way of Frame swap with a 96 2500. My transmission is a 47RE 2wd and I don't have the transfer case, linkage, or driveshafts yet. My questions are really specific to sourcing these parts and doing it the right way. So here are some questions.

Please keep in mind I am trying to do this as a budget build.

1) Would you try and source a 4x4 tail housing and output shaft for the 47RE or just try and find a used 47RE out of a 4x4? I would prefer keeping my transmission because I know where its been and how its been taken care of but wanted to see what you all thought.

2) As far as 241 transfer cases are concerned, a 241D, 241DLD, and 241DHD will work correct? I have a chance to get a 241D but its just the case, so Id need to match the output shaft somehow, and figure out linkage. Any thoughts there?

3) Those transfer cases listed above have no electronics, correct? So if I fab up my own linkage it can be done fairly easily, right?

4) How would you go about this? Would you try and find transmission, Xfer case, and driveshaft all together? Or do you think the parts can be sourced used fairly easily by in pieces. And mainly cheaper?

Any help is greatly appreciated.

If yours needs a rebuild...maybe just parts.

I believe those trans fers all have different shafts and spline.

D= is Dodge (i think)
DLD= Dodge lite duty (most auto 2500, 5 speed manual)
DHD= Dodge heavy duty (6 speed 2500, all 3500)

If i recall...i think that is the break down. I started a hunt for a DHD but didnt want to deal with the shafts

Ok thanks Stormin08. Went to a junkyard no luck today. Just gonna be on the hunt for awhile. I think I’ll wait to come across a DHD because to do any sort of conversion I have to switch the tail housing at a minimum. So I’m switching things anyway.

No Stormin, the TC do not all have different shafts splines by TC model but by the trani they were mated to. I don't know what a 241 D is or is from. All (98-02) of our trucks had had either 241DLD or 241DHD as options. DHD was probably std on 3500. Now the DHD does have a PTO access and a bigger input bearing and can have different input gear length and splines. There is three different lengths, mostly 2 are used. I think 23 spline on auto and 29 spline on manual, and most auto are the 4 1/4 length and manual 29 spline and may be 5 or 5 1/4 length. Internally the gears are the same but the DLD has the smaller bearing and chain.

I think Pirate 4x4 and other sites have a parts description and number chart with more detail.

Best to get a 01/02 47RE(match engine and PCM) 4x4 trani and a 241DHD from an auto(I do not think TC year matters.) But you want to match vacuum if you have CAD(4 post vacuum switch/plug. Does not matter if 2500 or 3500. DHD was common option on 2500. Or get a matched pair trani and TC with DLD.
If you do want to get a new output gear for the OD they are not likely available new and used is hard to find in good shape so do not mail order one. Trani shop can press them and R&R with new clutches for about 200-300 in an hour. I would do the new clutches either way if you have it. 2 sets fro 30 dollars each for parts, and an hour.

A lot of wholesale transmission parts stores like Transtar or PDQ dismantle and sell used trani and transfer case parts and rebuilt units.
Don't split transfer case "just to check it out". If it ain't broke , don't fix it.

You will be better off picking the drivetrain out of a donor truck that's 4x4. Here you can buy that stuff together much cheaper than parts or separately.

You will want either a 23 spline DLD or a 29 spline DHD (not sure the latter exists but I could be wrong).

If you're planning on high power down the road OR 4X4 launches I would go straight to the DHD.

Big Fish thank you so much! great info. I did find a spec sheet from Geno's garage that went over each TC pretty well. I'm a little confused on codes though. In the spec sheet it has the 241, 241D, and 241 HD. But in forums I read of 241D, 241DLD, and 241 DHD. I assume the spec sheet is using interchangeably D to DLD, and HD to DHD because it describes the D as a heavy duty 241 to withstand Diesel engine torque. I found a 241D that came out of a 2002 1500 with the 5.9 gasser, and am trying to figure out if that will work.

Thanks for the info on transmission shops. I found a transmission parts supplier near me on the west coast that will sell me the output shaft and OD Housing for $100 bucks. I am waiting to figure out the TC to ensure fitment.

I also need to confirm transmissions in the 1500's. Do you know if they were 47 re as well? My gut tells me they were not.

Of course I want a DHD but they are insane price wise.

PTS agreed. I wish I had the powertrain but just not in the cards. I'm hoping to make this work for fairly cheap. I've got some power added plans but nothing crazy. and minimum 4x4 launches I'm sure. I would love to find a cheap DHD but I don't think those two words go together lol

The 1500 is probably a D or DLD, N or DHD. 1500 trani is different model. Input gear and output yokes may be different in 1500 TC, not sure.

Those that say that input splines are different for DLD and DHD are wrong. the input splines ae not dependent on which TC it is, they are dependent on which trani it is mated to auto or manual, not sure if 5 and 6 speeds are different, maybe different length. Is the OD housing different for 4x4 and 2x4 or is just the output shaft/gear different and the TC replaces the 2x4 tail shaft on the OD unit, Not sure you need a different OD case.

You need 47re, either TC DLD or DHD with proper input gear. Trani and engine/electronics year group must match. 98.5 /99 or 01/02, forget 00. no 99 trani's on 01/02 truck engine.
auto TC input gear should be 23 spline and short gear 4 1/4 inch length.

The straight 241 or 241d may be from 1500's or other brand or year trucks, maybe V-8 trucks, not 98.5 to 02 Cummins 2500/3500 trucks. They were all dld or dhd.
