Ok to start with my friend had a 95 cummins and by some wierd crazy chance he got his hands on a free Nv5600 and took his kinda lazy but still working 47rh out of it. It was a 4x4 he still has the t case. I want to get the trans from him cause I need a TC for my good shifting 727. What I was wondering is I have a 2wd is it as easy as having my trans guy swap the output shaft and but a tail shaft one it or is there more to it than just that? Also will a 94-07 bell housing adapter work or is it more limited than that?

I wanted to trade my 727 to him for it cause he wants to use the 47rh for a jeep 4bt swap but he wants overdrive he has d60 d70 with 4.10 in them and wants to turn 36`s and drive it on the street.

 

If you want to make it 2wd all you need is a 2wd tail housing and output shaft and swap the guts or a whole 2wd overdrive section. To install it in your truck you'll have to shorten the drive shaft and you'll probably have to modify you trans mount a little bit. You would need to add 2 switches so you can control overdrive and lockup.

The 94 to 02 bell housing adapter will fit, I don't know about the 03-07's.

Even if you get the 47RH you're still going to have to do a little work to it so you don't finish it off.

 

ya I was going to do a few things to it. and get a goerend tc and maybe a vb well it seems like it is going to be a lot of $$$ to find a 2wd od unit and tailshaft/output shaft. do you think I would be better off finding a 2wd 47rh rather than trying to find all those peices. I wish I woudl have known that I was going to buy this truck we just parted out a v10 it was also a 4x4 but I could have got the trans for free with a broken bellhousing. I could have sold the t case to help on $$ for this project and I would have had some other parts. I think if it is going to cost more than I paid for the truck($2500) I might just buy a tc for my 727 and live with it for now untill it blows then swap or maybe ill come across some stupid good deal before then like a free nv5600 or 4500.

 

Its not hard to put $$$ into an auto to do it right. I have close to $2200 just in parts.

Go down to the trans shop and see if he can find a 2wd tail piece in the used parts scene. Shouldn't be too hard.

 

Spend the money on the 47rh, you will never regret it... Exspecially the first time you hit the lock up switch...!!!!

 

you will also need a 2nd gen starter and if you can upgrade the flexplate to the second gen that would be a good move also.

 

Yeah, rub it in our faces why don't ya?

 

Sorry!! But it is the best 500 bucks I ever spent... I got one heck of a deal... Just wish I would have had the extra cash for a rebuild...

 

look in the classifieds there is a 47rh 2wd trans now. I wish i went that route instead of my getrag. I would love to have a built auto instead... but i am sure if my rag wasn't a unusual noise makers... i.e bad bearings and syncros... i would like it better

 

You can bolt your OD housing from the 518 onto the 2wd RH.



They will work beautifully together to effectively make a 47rh 4wd trans.

 

I've done that, took the OD parts from a 518 and used the front of a 47RE and the overdrive guts and made a 47RH out of the mess. The RE has stronger parts inside.

 

where do the 2nd gen trucks usually have their lock up switches?

 

they don't, only have an OD switch. I would assume it is controlled by the computer.

 

That is correct.
