A727 ==> NV4500?

Postby 90chum » Wed Oct 17, 2012 7:02 pm

I'm getting tired of the old slushbox
-I have an nv out of a 93 chev 4x4 diesel that needs a bearing under the one gear
-there is an nv out of a 98 dodge 4x4 for sale that needs 3rd and 5th gear (one broken, one stolen)
i was wondering how feasible it would be to make the swap, or if i should find a getrag, or some other auto. i have been researching it and can find a wealth of nv parts on ebay to fix it.
what i would like to do:
2nd gen pedals, hydros, bell housing, and starter if need be (have access to small machine shop and places to get hoses if needed)
a fixed nv (prefer from the chev because its free to me), proper input shaft, and anything else i can find it needs
either big single or dual disk
rebuild my np205(needs it)
so...whilst reading, i've heard: the gm nv has a different bolt pattern on the front, the auto t-case has a weaker input that wont handle behind a cummins with no torque converter and much machining is needed to put the bigger input in the 205, the 2g bell makes the starter hit the frame, something about cutting where the throwout rides, the bigger input shafts wont work in the gm

am i missing anything(parts or differences), and can anyone clarify any of this, i figured the nv's were the same except the input and it would be slam bam nv 1st gen. or should i locate a getrag? or build the 727? or a better auto?

The early NV4500 have a small input that cant be swapped for a Dodge input if im remembering correct.

So would it be better/cheaper to get the other trans and combine them or to find a getrag, or just build an auto? I would prefer stick, and have noticed people having less problems with the nv than the getrag, but if its going to be astonomical to go stick, i can deal with a built auto. Also, does the np205 bolt up to the nv?

May be able to combine both NV's and make one good one. No matter what it wont be cheap
You will either need the AA adapter kit or the second gen motor plate,starter, bellhousing and the 23-29 spline adapter or a 29 spline 205 if I'm remembering right. If you could find a complete donor fog the Getrag swap it may be chePer.

I also recently got a possible lead on a 47rh, and the tranny builder for the local pulling shop said he has a very lightly used beasty converter hed sell me cheap, and id have him check it out and put a shift kit and what not in it. Which im kinda leaning towards, as much as i want a 5spd, im told that itd be a bit cheaper and a lot easier to stay auto, and better for the occasional pulls and tows i do

I think so. You will need a 2nd gen block plate and starter as well.

I believe it will be a package deal of engine, trans, and t-case from a 2g, i was reading some have issues with the starter hitting the frame?

I suspect that happens when you have a "short" frame, like my 2wd, and not with a "tall" frame 4x4. If I didn't grind a bit off of my frame, I know it would hit, but if the frame was 2" taller, the starter would have plenty of room. My frame is 6" tall by the starter for reference.

I have a 3rd gen starter on mine, and it is really close but does not hit, if anything, when the engine has a load on it the fuel lines will hit

I was in your same situation a few momths ago and did a rag swap and regret it ever since... my vote is a built 47rh ... also less work going from auto to auto then from auto to stick

i'd disagree with you here, having just gone from a 727 to gutbag. its not a big deal, just sayin. also a manual swap could be good for him if he's not looking to drag race. it all depends on what you're planning to do, and what you're most used to.

He ended up selling the engine to someone else, but i got the trans and t-case. Is the block plate the same as the 727 or do i need that included as well, havent picked it up yet and want to know what all i need to grab.

You end up with a 47 rh? If so you need the second gen block plate.
