After Siler_Dodge's post I called my cousin who owns the transmission shop and told him what his mechanic told me I had. He called back and agreed with you guys, It is the NP231. Sorry for the confusion as I could not check it out personally because it was there. He's had a nice talk with his employee about not guessing. I'll now look into a NP1231D model.

For my 2001 Ram 1500 4X4 can I replace the NV241 Transfer Case (The NV241 is essentially a NV231HD with six gears in the planetary set. )
with the NV241D ( The NV241D is a heavier duty Dodge version of the 241, with a larger input shaft and larger bearings to withstand the torque of the V10 and diesel engines. )
or the NV241HD (The NV241HD, an option on Ram 2500's and standard on Ram 3500's built after 1998, has a stronger case and wider drive chain to better withstand the shock of snow plow service, a PTO cover and drive gear, and an extra bearing to support the thrust to the main shaft created by a PTO adapter.)

If I can has anybody does this and does it take major re-work of the mounts and such? Any infor anybody can provide would be appreciated.

Thanks!

 

Honestly, i'm impressed that your 1500 has the 241 to begin with. I have the 231HD, and it seems that most 1500's I have seen have either the 231 or the 231HD. I think you can do the swap you want, but you might need to change the input shaft because the number of splines is different.

 

I thought the 1/2 tons also had NP231's as well. I'll be darned...lol.

Thanks for bringing this to my attention as I might have purchased a NP241 series for replacement and ran into issues I was not expecting.
