I like to switch transmission from my standard ('77 W-200 M-884) 727 autobox with a married 203 to a 435 manual divorced 205.

At Frame level, what do I need to change?
I thought the 435 has another traverse compared to the 727?

I didn't have to change anything on mine, but mine was also a 1983 swap to 1983 swap. I had a 727 with a 208, swapped it to 435/205. I encourage that you do your research before the swap. The most important piece of information you will need to look into will probably be driveshafts and output yokes. Your driveshafts will need to probably be adjusted in length at a minimum. I am assuming your front shaft will be too short as the 203 is a big T-Case setting it back farther than the 205. The rear may be too long as it is now again because of the big 203 case. Also the output yoke on the 205 is probably much larger than what came on your 203. Mine was compared to the 208. I believe it is 1350 or 1410 on the 205. Your 203 is probably the old Detroit style. Get your measurement gauges out and that will help you. Here is a link to common sizes for both styles...



Be sure you get all the pedals and accompanying linkage when you are sourcing transmission and transfer case. Also get the female to female coupler! Output of 435 transmission to input of 205 TC. This is a $160 dollar part if you don't get it and is only used on the 205.

@ Neil 4224:
I got almost anything from the bellhouse to the drivelines, it came from a '72 W-200.
only things missing; the (I think different ) traverse and pedals.

The "beam" which connects the left long framerail to the right long framerail, in which the transmission rests.

We call that a crossmember. It should be the same for a 727 and 4WD NP435, but with a 2WD version for a divorced NP205, you will probably have to find a 2WD crossmember. Make sure you get the crossmember with the NP205 as it's a pain to mount one otherwise.

What do you mean with 2 wd or 4wd version?
I mean it's a transfer case, as far as I know you find them only at 4wd's?

My bad didn't read your original post clearly enough regarding divorced setup. This quote above is correct!

If you have everything from the donor then you might be able to make a driveshaft combination work. Don't worry about the coupler if you have a divorced setup. Also snag the pedals they are hard to come by!

EL, is correct. I believe this is unique to the divorced setup. There are specific crossmembers for each since it is divorced (2wd crossmember for the tranny). You probably can make something work with what you have but will require some additional hole making in your frame for mounting.

well, these holes are not the problem, the crosmember is, it's probably scrapped with the rest of the truck 15 years ago.

The divorced setups used in '74 and earlier trucks used the same transmission as a 2WD truck. They just connected a short driveshaft to the transfer case instead of the rear axle. There was no such thing as a "4WD transmission" back then, you just either had a transfer case after it, or you didn't.

Didn't the 727 for the divorced 4wd's use the short shaft tranny, not the standard 2wd version.

I think all the Dodge ones are the same, with the yoke right off the main casing. I think Ford had a long 2WD version.


Ah, I missed the "727", I thought we were still talking about the NP435. I don't really pay any attention to women's trucks. 😝

Yes divorced 4wd used the short shaft fixed yoke 727. I have seen this tranny in 2wd trucks. But I have also seen the long 727 in trucks if I remember correctly.

I know the short shaft is used in any application, that requires a two piece drive shaft, Crewcabs and motorhomes, at least.

^^Correct. My 85 D350 crew cab long bed had a short 727 with 2 piece driveshaft & carrier bearing.

They used the "Shorty/ Motorhome" 727 in 2 WD trucks?
I didn't realize that.
Or are you referring to manual trans?
