sorry for the airdale question

[heartland41]

I was hoping to glean some information for those who have volumes more knowledge than myself. I have the opportunity to purchase an M35A2 from a friend. The unit in question is the standard 5 speed. I was wondering if it were feasible to replace the 5 speed with an Allison Automatic transition. I know "anything is possible" but I was hoping if someone could tell me if this swap were feasible and or even possible. The engine in question is a White Multi Fuel.
Thank you

possible? sure. Practical? depends on which allison is used. if it has overdrive gears, it'd probably be ok. If not, you will make the deuce's low top speed even lower.

The deuce is rated at 54-56 MPH at red line on standard 9:00X20 tires, goes up to 63 with 11:00X20's...... The M35A3 with the Allision 4 speed auto I think can barely clear 55 and is very near its red line too.....

Can I ask the reason for the change? Do you not want to drive a manual, or want easier cruising? If you just have to have an automatic, I would look at an A3.

Allisons come in a variety of configurations, even within a single model line.
Overdrive, direct, underdrive, retarder / non-retarder, one neutral position or two, pto / non-pto, etc. If you're putting this into a deuce, make sure you get a non-electronic Allison or you'll end up having to put an on-board computer in to control up and down-shifting, and kick-down.
The bell housings are SAE bolt pattern so bolt-up isn't a problem although you may need to go with an adapter, SAE3 to SAE2 if I remember correctly.
The question boils down to how much time and effort, and money do you want to spend on the project?

Allison has a whole bunch of information available to help you make some sense of it all. Also a little handbook called "Mechanic's Tips" that takes you through the installation and set-up.
These are free(?) from your local Allison dealer.
Once you've made your choice, you can always start scouting the local truck wrecking yards armed with a specific model/build number. The serial number decodes to how a particular transmission was built.
The litany here is "read the manual" and it's definately true with this one. Doing your homework can save you a lot of grief and headaches and wasted effort.

An automatic wouldn't be as cool as a stick.
Heck, Clint Eastwood wouldn't have been as cool as he was if he had used an automatic in Dirty Harry.

Here I was excited because the subject says airdale, the name of aviation sailors on a carrier.

Talk about a let down.

If you decide to do the deed you might look at used school buses...they came with automatics and were well maintained.....might even consider an engine and tranny swap.
