Speed Posted February 11, 2011 Share Posted February 11, 2011 Hi all; Hey,I was looking at a transmission attached to an old Mack school bus engine I have,and wonder what it is;I don't have books for anything but what came in my EH originally. Here's the ID #. TK 311 If you can tell me a little about it,I'm wondering if it might be worth installing. Thanks for your help!
