Help with Id of this transmission

[notyepcars]

I was wondering if this transmission is 727 IH? I had a 78 Scout which I crashed 25 years ago, I salvaged the transmission and had it stored at my uncles large storage shed. I now need it for my 73 1310 pickup. I ran the casting number on the transfer case, and it up Dana 20, however I see absolutely nothing for a id plate of the transmission. Thanks

That is a IH tf-727 automatic mated to a Dana 20 transfer case as used in IH Scout II applications. (Scout II, Scout II terra and Scout II traveler)

the transmission part number is stamped into the case just above the drain pan on the left side, visible in pic .003.

The IH pickups & travelalls used the same transmission, however, with a divorced transfer case....utilizing a short drive-shaft between the transmission output & the transfer case input.

As it sits, the transmission and/or transfer case is ill-suited for a full-sized IH 4x4 vehicle.

As scott said, the t-case is a no-go for your f/s rig, but the transmission could be made to work by exchanging the rear adapter housing and output shaft for an IH full size tail housing and corresponding output shaft. It isn't a simple bolt off/bolt on job. Assuming you have the correct donor parts from the apparently defunct 727 in your 1310, both transmissions would need to be completely torn down in order to do the swaperoo. This is all a moot point anyway, as you'd be ill advised to rush any auto trans that was not carefully prepped for storage back into service after so long without doing a complete overhaul. The rubber seals have shrunk and rotted. Any atf that was not purged from the system has completely deteriorated from a chemical standpoint, and has likely been contaminated by 25 years worth of moisture condensation cycles. Not saying its a worthless pos, but it is a builder core that isn't ready for prime time just yet. What's the story on the trans in your peekup? Probably money and certainly time ahead to have that one serviced if possible.

My 73 1310 4x4 actually has a allison 540 4 speed auto in it now, conversion out of schoolbus. It is set-up with the divorced NP205. My donor vehicle is a 72 1210 2wd with a t-19 in it. So I am basically screwed as far as using anything I have now. I am just trying to make a original functioning/looking truck out of the 2 trucks I have. If I were to try to find another donor vehicle, that would have everything I need from transfer case forward to engine, what years of pickups and Travelall's would work? Because the 73 was converted to a floor shift, I need a complete steering column with linkages to transmission, plus linkages for the 4wd. Thanks

That allison setup sounds pretty cool. Is there something wrong with it? 4x4 versions of the d-series pickalls use the NP205 regardless of what transmission is up front, so you're good there. If you weren't opposed to going with manual trans, you could swap all the necessary parts over from your 2wd donor and be good to go. The t-19 will mate up to the divorced t-case. With what little I know about your situation, this May well be your best option. To stay auto, you'd need all the associated parts from any d-series ('69-'73). The '74-'75 rigs have set back engines and the auto shift linkage on those is total crapball garbage to be avoided like the plague. Also, the autos in early d-series, at least through '71 were borg warner models, which aren't bad units. They just aren't as popular, and therefore support in the way of rebuild kits and torque converters isn't nearly as good as it is for the 727. '72 was a transition year for autos in IH rigs, with the remaining bw inventory being phased out in favor of the 727.

The allison 4-speed auto is a beast, very hard shifting, it will slide the truck sideways on snow and ice when it downshifts in 2wd, plus it doesn't look the best with the shifter mounted to the center console. It also snapped several flywheels because of the torque. I have a very nice 72 1210 2wdthat I am trying to put the entire drivetrain from the 73 1310 4wd single rear wheel under, have already pulled the engine, tranny, and rear axle. So what your telling me, a 72 or 73 auto, 4wd pickup or travellall would be my best bet if I want to switch it to an auto. Thanks

Is it just me, is there a major contradiction going on here?
I'm confused dude. In one post the '72 4x2 is identified as your parts donor. In the next post it has suddenly morphed into your project builder and the '73 4x4 is now your parts donor. I get that you want to combine parts from the two in order to make one solid runner, but which is which? I'm also gathering that you're completely opposed to the manual transmission option. Other than that, this whole thing is about as clear as mud.

Sorry for the confusion. My plan is to take the complete drivetrain out of the 73 1310 and it put it under the 72 2wd, the 73 1310 is pretty much shot as far as the body. My Dad bought the 73 1310 in the late 70's so it has a lot of sentimental value to me. It was originally a automatic and I was trying to get it back to the way it was when it was new. I am not opposed to the 4-speed, but if I can find the correct parts to convert I will do so. I have already removed the engine,tranny, and rear axle out of the 73. Thanks

Thanks for the clarification. It all makes sense to me now. Well, I think we've pretty well covered what you will need to go auto. Its too bad the 727 you have is set up for a Scout, or you'd be well on your way. It shouldn't be too hard to source the correct version or even the necessary parts to make the conversion, but if not, the manual trans is a pretty nice plan b, and it's already in the truck! Good luck to you, whichever way you decide to go.
