Hello all,

I just picked up a 90 W250. Gas 360 with 4 speed manual transmission.
I’m not familiar with the manuals other than the getrag in the diesels. Does anyone have any info on what transmission this may be?

Thanks

Should be a NP435.

Unless someone changed it, it is a NP435.

If it's a granny gear 4 speed, it's a NP435.  Anything else would require a lot of changes and some obvious cobbling of various parts.

And yes, the NP435 was available at least through the '91 model year, possibly early '92.

Would the identification tag have the info on which version the transmission may be, low granny gear or not.


Also, I haven’t been able to find any info on wether or not the getrag 5 speed or NV4500 5 speed will bolt up to my 360 v8?

Thanks for the replies

NP435 was offered in two 1st gear configurations, one Granny one not.
It was only chebbys (maybe fords also, I know little about them), that had two gear ratios. Dodge did use the NP445 in the mid 70's which is similar, but has a synchronized first gear with a relativity normal first gear. Dodge did use two versions of the NP 435, but they were a time issue, one up to about 1987, then another after. The difference is in the internal parts, most of which cannot be w=swapped from one to the other. Also dictates which PTO's can be used.

Any of the trannies without a granny gear, are hard to start out in second. granny gears can be skipped for most normal driving. One trip, and you will know what you have.

Novak has lots of wrong info on their site. Show me a Mopar part number, or a shop manual that shows the different ratios. Maybe they did in the 60's, I do not mess with those. In the 70's Dodge used the 445, with a 4.59 synchronized first gear, and 4.07 reverse. I have nearly every dodge shop manual from 70, to 93, and several later ones, along with many dodge parts manuals. I have never seen any mention of a Dodge close ratio 435.

The only NP435 offered in the '72-'93 Dodge trucks is the granny gear version. There are a couple different versions of the NP435 used, but all had the same 1st gear. The differences was more in bearing sizes and the PTO ports.

Ok, so 60's. Slim chance he will have one in a 90.

You sure that is not a 445? from memory, it looks more like the 445, then the 435.

I was looking for the Email i got from Novak, but cannot find it. They basically said it does not affect what they sell, so they do not care.

Ok, thanks.

If possible, can you post some pics from all sides, so I can add them to my collection.

Thanks. I'll try not to forget that Dodges existed before 72.  ;)
