Multifuel Automatic Transmisson?

Multifuel Automatic Transmisson?

Here goes my first post of hopefully a never before asked question.

Will the Allison automatic transmisson used in the A3 work in a Multifuel A2 truck?

Does the bell housing fit?

Has anyone done this? How did you manage it?

My reason for asking, I really like the idea of the multifuel engine. I also like the idea of an automatic transmisson in an truck that will see highway and offroad use. I also know from experience driving my Thing in parades what a pain the clutch becomes.

Thanks,

I very much doubt you will get any good info back. I do not remember anyone putting an auto behind their multi. I know nobody would use an A3 trans because it is not an overdrive unit. If it would be done, you would want one with O/D.

In parades, use low range on the transfer case and first or second gear in the transmission, engine speed at about 1000 rpm's. Should not have to use the clutch very much if you do that.

Cranetrucks 8x8 5t tractor has a multi AND a AUTO oem

Yeah Ron, but he asked about the A3.

My heart isn't set on the A3. Overdrive did not even occur to me. Does the manual 5 speed include an overdrive?

I am just thinking outside the box and I don't have the knowledge of MVs that the rest of you have.

Most parades are slow and steady. Mardi Gras parades are constant start and stop affairs. You may stop for 30 seconds to 30 min. The organizers and police are constantly telling people to bunch up and stay close together.

I appreciate all the responses.

The bellhousing is SAE #2 , the trans adapter #3, I'm sure you could come up with an Allison 545 that would bolt up to one or the other. The catch is the flywheel, you might be adapting the one that the trans was behind to the Multi crank hub, and then there is the starter to turn that flywheel though I'd guess unless there's something really odd about Multi starter/flywheel dimensions it'll work out if you have enough time/money/patience.

Yes the 5 speed has an overdrive.

why not just buy a M35A3 or 939 series 5 ton? They come with automatics.

No offense, but I'm sure those are out there in big numbers.

No offense, just pointing out that the multi and a auto WAS a factory combo, may be not in wide use but WAS a military use combo, so some one did put a auto behind a multi.

Point taken. My statement was about any custom jobs guys here on the site have done.

I can say for a fact that I wish my Allison automatic was an OD unit, even after only 50 miles of driving my A3

Because they burn diesel and I would not be able to (easily) burn WMO or other fuels like the multi-fuel engines can.

Not 100% on this but I thought that it has been said the trans in the A3 is electionic.?. It would be had ($$) to mode that to a muilt. That is not to say that you could not get a different auto to go behind the muilt. On another note I thought (not 100%) that they (military) tryed the auto out of the M135/211 in the M35's. Don't know if it was the reo or the muilt.

Now remeber I'm not 100% on this and I did NOT stay at a Holiday Inn last night

You need to be CLEAR about what you say, NOT rely on mind reading (though that might be fun and scary) since some hang on every word you say, you being one of of the site BIGGEST KNOW-IT-ALLS

Thats a first. Usually when someone calls me the BIGGEST, its followed by azzhole.
