oifla Posted yesterday at 12:06 AM Share Posted yesterday at 12:06 AM 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 O. Quote Link to comment Share on other sites More sharing options...
Joey Mack Posted yesterday at 12:38 AM Share Posted yesterday at 12:38 AM 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?? Quote Link to comment Share on other sites More sharing options...
steve s. Posted 5 hours ago Share Posted 5 hours ago 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 1 Quote Link to comment Share on other sites More sharing options...

Baby quad? Thanks! O. Quote Link to comment Share on other sites More sharing options...
