One thing I really wish I had on my 2005 W24 chassis was a push button shifter or better yet, paddle shifters. I have a hard time watching the road and trying to get the gear selector in the gear I want in hilly areas. Would be much easier with the buttons!

Anyone ever make this type of conversion or read of it being done?

Interesting. I've thought the same thing. I'd really like to have pushbutton shifting as well. I don't think it would be an easy change though as it needs an electronic module mounted on the trans to make the shifts as I understand it. Not sure if the existing TCM can handle the function or if the TCM would have to be replaced as well. If you had access to a Mountain Aire gasser salvage unit, you could probably score the parts needed as they did use the pushbuttons at least for some years.

WCC offered a PB shifter, but only a few coach builders opted to order it. WCC did not use an Allison brand shifter, but rather used one made (or sold) by Arens. Since the Arens PB shifter became a "WCC" part, I would think Jon or Alan at Ultra would have info as to its availability now. FWIW, I think the column-mounted "shifter" is also fly-by-wire, so the electronics MAY already be there.

Please let us know what you find out.

You might contact Harry Mahre at Power Shifts NW, best Allison guy I know.

It appeared to have been an option on the Allison 2100MH five speed and you need a “neutral start backup” NSBU switch as well as the keypad. Need to find the wiring diagrams of both and place side by side, but on the outside it may not be worth the cost.
