M211 tranny in M35

[halftrack]

Correct me if I am wrong, but didn't the Army experimented with putting the auto tranny from the M135/211 trucks in the M35? If so, was this a direct bolt-up? I am toying around the idea of doing this modification if it doesn't involve making a special adapter to the multifuel motor. Wouldn't this be the best of both worlds? A known reliable auto tranny in a known reliable truck! Has anyone tried this? Of course I wouldn't ruin a good running M211 for the tranny, I would pull one from a junker somewhere.

you would sacrifice speed, no od. and the multifuel probably has too much torque. allison would be a much better choice and it would bolt right up.

*exposing ignorance*
did the 211 achieve low range in the tranny?
if so using one in a M35 would result in high range, low range, and very low range.

its was the power pack of the GMC. the engine, trans and (we dont know what tcase was used) but there was a program to use the GMC power train in the M44 deuces. I m in the process of doing this to me M35 deuce as we speak (with the help of Dave)

Yep, the army (actually GMC, at the Army's request) put the hydramatic in the Reo - but as Westy says, they also put the GMC 302 gas engine in too. This was well before the Multifuel came out.

By the way - the army conducted a lot of dynomemeter test on the Reo's and GMC's when the designs were new. The GMC produced considerably more drawbar pull than the Reo.

Thanks for the schooling.

The Allison AT545 would be a good choice except for no overdrive. I've seen them for $300-500. SAE 3 mounting.

 

[m-35tom]

did the hydramatic have overdrive? did it have a lock up convertor? if 2 no answers = very poor choice for low rpm multifuel. the allison would be like driving in 4th all the time. ok for off road but not much else.

Been to the local Allison dealer, there does not seem to be an OD+lockup model they thought would do the job until you get into the $$$$ electronics control ones. Anyone find different?

There is the "1000". might be too long.

[m-35tom]

as far as i know there is no really suitable trans due to length or $$$ if you have to have automatic allison is the only real choice. the 3060 without "P" (pto) is short enough to go behind a V8. everything seems to have its own set of problems. that is why i am going forward with od for the 3053 trans. even as expensive as it is, it still gives you everything you need.

I'm just asking because I don't know. What about the autos from a F350 or Ram3500. Would they work???

 

[OPCOM]

I think that if there is no suitable medium truck xmission swap, either manual or auto, Tom-35's gear kit is the best idea. The deuce transmission is short in length and there's the rub. I've done some looking around and so have others who know more. The only other thing I could think of to give an extra gear up for the rears only would be a motor home (heavy) type OD unit mounted after the T-case. Far more costly than the OD gear change itself, the air tanks would have to be moved, and woe be to him that engages such a thing at 55MPH while the air-shift is on!

engine tranny combo

What about an engine tranny swap from an school bus. Used ones are fairly cheap and they might rpms to make up for the lower gearing of the deuce???

RE: engine tranny combo

when i had the 3208 engine which would turn 3000 rpm, i also had a .66 od. most of the time was spend running at 2700 rpm, 68 mph. school bus trans do not have od so there is that problem, it would be like driving in 4th.

RE: engine tranny combo

now if someone can find me a 9 litre international at a good price i would be interested in putting the 3053 behind it.............

...and woe be to him that engages such a thing at 55MPH while the air-shift is on!

Amen brother OPCOM! WOE, WOE, WOE be upon him!

 

[Stretch44875]

Dang, I tried to sell the 9liter out of a bus and no one wanted it. Sold the whole bus for 700. Is it smaller than a 3208? Redline was 2800 and we ran it at 2700 for hours.

[m-35tom]

the 9 litre is, well, 9 litre. the 3208 is 10.6 litre but is real noisey. school bus might be ok, but probably high mileage.......
