What model to get nv4500 to bolt up to dana 300

I was wondering what year and model to get a nv4500 trans that would bolt up to a dana 300 transfer? i think i heard somewhere that it was a gas dodge. and anyone that has done this what else did you need to get the engine to mount to the trans and the right clutch?

Thanks

Jacob

I did it, look in my build thread. The ones that came behind dodge gassers have the correct spline count to mate to a Dana 300, however, around '96 or '98 on you have to change the input retainer on the D300 because it hits the trans rear housing. I had to do this, it is documented in my thread.

As far as mounting it to the engine, there are three input shaft types. Dodge had a large 1 1/4" input, Dodge and GM both had a 1 1/8" 10 spline input which is the same as several stock CJ trannys. The dodge input is a little longer, you can use a adapter plate between the bellhousing and trans. Its cheaper, but add a little length to the drivetrain. The 10 spline GM input is shorter and requires a full bellhousing to mount it.

I wound up with a GM input and a dodge Gasser output, with a new input bearing retainer on my D300. Its a long story but worked out well, it was the cheapest route for me and I wound up with the shortest drive line possible with the nv4500, I also have a short shaft D300. Advance Apadters were helpful, but after several phone calls I found that some people there are more knowledge than others to say the least. The best prices I found on Advance Adapters stuff was through A to Z fabrication, who gives a discount to forum members.

The nv4500 build and install starts on page 26 of my build thread, linked in my sig.

so is there a difference between the dodge gas and cummins trans housing? the reason i am asking is if i can get a cummins trans put a gas output shaft of and still have the dana 300 bolt on depending on the trans year for the bearing retainer

Mine is a '97 gasser housing, new gasser mainshaft, all other internals from a '99 dodge cummins, with a gm input shaft. The are a couple of differances through the years, like the size of the reverse idler gear and early GM's had a lower first gear and different input bearing retainer because it used an internal slave cylinder, but as far as I know, the cases are the same. The dodge cummins had the larger 1 1/4" input which means a stock jeep clutch disc will not work with it, can't help you there, but I'm sure advance adapters can

Another option if you get the cummins version is to change the input on the dana 300 to match it, that may be cheaper and easier. my mainshaft needed to be replaced anyway so I went with the gas 23 spline output version.

This is an interesting thread to me as well. I plan to make this swap as well and find myself equally confused. I will be looking at TKFIREMAN's thread.

the input shaft isn't hard to change. Spend some time on advance adapter's website and you'll see how price will change depending on which trans you get. I hope I'm helping and not adding to the confusion.

these guys are very knowledgeable, but also very proud of their parts. I bought their rebuild manual, it was extremely helpful with step by step pictures and instructions for rebuilding a nv4500
http://www.quad4x4.com/NV4500%20transmission%20.htm

There are several other sites with tons of info, when I started on mine I was lost as an easter egg, but a lot of reading and a few phone calls got me straightened out. I'll help you with anything I can, but I am far from an expert

I just put mine in and I had a hd diesel unit and I swaped the output shaft over to a twenty three spline gas and used a clocking ring to get by the shoulder on the dana and to avoid shorting the gas output shaft.

Short answer is, the Dodge gas version bolts right to the Dana 300.

I asked a ref if he could give me a technical foul for thinking bad things about him. He said, of course not. I said, well, I think you stink. And he gave me a technical. You can't trust em. -

ive been doing a little looking in what time i have had and i might be getting a cummins nv4500 out of a truck that has a junk frame. it looks like there are kits out there to change the input on the transfer case to match the transmission and looking for a new output shaft is probably going to be more expensive. so if i can be the right spline count on the transfer case to go on the trans in think the dana 300 should bolt to the nv4500 without a adapter plate. the kit i found is here

hello, i just put an NV4500 mated to Dana 300. I am having issues installing the slave cylinder between the fork and the housing. I have a feeling the fork is backwards. Do you have a photo of the slave and fork? Thanks, Daniell
