Got my Allison "Mode On"
Feeling really "dumb" this evening. I have had this coach 4 years now and over 30,000 miles in those 4 yr. I have been over this bus from one end to the other wrenches and rags, done all of my own maintenance. I've "thought" I have read my "Big...

You may look around for a recent post by me on the same subject. Not the only one.

Mine is programmed to default in the economy mode. I am in the opposite position as you. I have only ran mine in power mode a couple of times in nine years. I will have to drive it in the power mode more to see how it feels.

Thanks to recent comments on this subject, I ran mode on for the 1700 miles to Houston and back. Ran great, didn't downshift and never slowed down. Granted, not a lot of "hills" through Tx, OK, & KS but it was still impressive on how well it ran.

The mode setting shows how much torque your particular Diesel engine has. 

Some motors have more torquey drive versus hp.

In other words some motors pull hills faster downshifted and revved versus up shifted and use the torque..

My m11 after mods...

I guess the earlier MD3060R were programmed differently?
My '95 build 4673 is economy (I assume) with "Mode On"

Here is a document that tells when they changed the default mode

On our coach mode "ON" is economy.  I leave it "OFF" running in city "stop & go" traffic cuz the coach feels more "lively" in that setting.  It holds the lower gears longer, which makes it feel more nimble, and if a burst of speed is needed it...

Ya, that Foretravel document in reply #6 is quite confusing.

If it were stated in language such as this, THEN it would be clear:

 When first started the engine, the Allison ECU will be in XX mode. This is the "default mode". 

Pushing the mode...

OK, I talked to James at FT and first not sure what a 3066 trans is as that is what the document says but if that is a type-o the following applies

coach #5746 and newer the default would be Power and if you hit the mode button it would be...

So Brett, did FT use any of the MD3066's?
If the MD3066 came out in 1996 which one would my coach have in it?

Steve,

I'm not Brett but the best way to know exactly which transmission you have is to crawl under the coach and look at the tag on the transmission.  It will be on the drivers side of the transmission next to the power cable.

I am Brett, and Mike is absolutely correct.

Copy down both model and serial number from that embossed tag.  Use it when buying Allison filter kits or any other Allison parts.

I've owned this coach since 2006, never messed with the mode button. My build # is 5400, I believe my default is economy mode, mode on power mode. Faster up shift , down shifts quicker. Don't know as it much matters much to me as I manually...

I do the same (use up and down arrows to choose the correct gear).

Leaving the transmission in economy mode gives the driver more control over shifts.  Always hated for the transmission to downshift 30' from the top of a grade or a freeway...

I too find it easier to manually control the shift points with it in Economy Mode.
In Performane mode it shifts down too soon to suit me.
It has made a big difference in the use of cruise control when climbing small hills and some steeper...

Did not know about the economy mode and used it yesterday after reading your comments, it was great, I liked the shift points better....and may have saved enough diesel to pay the cost of my first beer!
Thanks all!

My Allison four speed does not have the mode button,
But I do like the lockers in all gears,
I can put it in the right gear before going down steep hills and it stays there, Second or first gear,
We have a 60 MPH limit here for all heavy...

Correct.  The mode feature is only on the electronically controlled 6 speed Allison transmissions.
