The Allison is a fully automatic torque converter driven, electronically controlled 6-speed automatic transmission that is commonly used in coaches and heavy vehicles. The Cutaway Allison Transmission has been specifically designed for teaching heavy duty automatic transmission theory and operation. It has been strategically sectioned and cutaway to allow students to visualize the internal transmission functions.
Educational Advantages:
Gear changes can be made using regulated air pressure and provided controls
Driven by hand crank
Allows visualization of gear changes, planetary gear sets and clutches.
