+1 to this! Great advice here!

Too bad you dont live near me , theres a Dodge 2nd gen Dana 70 in my garage looking for a new home.

 

Ok, so found a good deal on a 47re 2WD. My tranny in my truck right now is an 01 2wd tranny with a 4wd overdrive unit. The truck is a 98 so internal harness had to be swapped. I did not do this myself; how hard is it to swap overdrive units, and what are the acceptable cut-off years on which trannys had same electonics. I know the earliers are 47rh's, but which are good for what? I know 98 doesn't work with 01 lol, but that's about it. Can you put a 47rh in and its all hydraulic no worries? Thanks for the help guys

 

94-95 (and maybe some early 96) will be RH transmissions. 96 and up are RE, I believe the internal electronics changed in 00.

You *can* install the RH trans in the newer trucks, but, the check engine lite will always be on, with trans codes..... O/D and TCC may not work because of that as well.

 

So I'm looking into doing this swap
I just got my hands on a 2nd Gen 2500 that was salvage by being T boned
Engine and transmission is intact as well as the axles
My only question is what's the best way to go about transferring all the parts over to my 1500?
Do I need to lift the body off the frame and how do I figure the little tedious things I need to do?

 

Depends on what you find easier. When I swapped from diesel to gas you fixed the tedious things add they pop up.

 

What year is the donor, and what year is the truck you want to put it into?

 

The donor is a 2000 and my truck is a 99

 

Should work. Use the PCM/wire harness/trans from your donor. I *think* the rest will work.

 

Anyone have an estimate of how long it took?
I have access to hobby shop on the base I'm stationed at to give you an idea of what tools I have available
I just want to know how long I'll be without a vehicle

 

Depends on how well it goes, and if you have someone to help. At least several days, if you have absolutely everything you need, and don't run in to unforeseen problems, more like a week or three, working on it full time.
