Mack transmission with SAE 2 bell housing?

[oifla]

Hello all

I'm interested in twin stick transmissions. I've done a few searches but I'm not coming up with the info I'm after, thought I would ask you all to see if it's worth chasing this down further (or if its a non-starter). I'm not a Mack guy so pls forgive me if this is a dumb question. 

In short, I'm interested in finding out if there's a Mack transmission that will work with an engine that requires an SAE 2 bell housing and has overdrive gears. Is there such an animal? Older units and/or twin sticks are fine (wouldn't mind that at all for my application).

Thanks

what years are you asking about..  mack transmissions that I deal with have a 1 piece front case with a Mack bolt pattern.  Eaton and Meritor transmissions require a Mack bell housing.  Mack's have the rear engine mounts on the bell housing.  with this said, I have never bothered to learn about SAE bell housings,  so I will follow this for my own education..  do you have a truck in mind?  Model and year??

The short answer is yes. I can offer two examples; I have a B model the was a concrete mixer. The mixer was driven by a flywheel PTO. To make room for the PTO shaft, Mack used a #1 to #2 reducer at the flywheel housing, and a # 2 at the transmission. This truck had a 673 diesel and a double overdrive Quadruplex transmission. I have another transmission kicking around here that is a "baby quad" that came out of a smaller gasoline powered Mack. I think it only has one overdrive, but it will mate up to a # 2 flywheel housing.  Steve
