We offer a dependable inventory of used AM General transmissions, inspected and tested to ensure optimal performance in demanding conditions.

Our selection includes automatic and heavy-duty manual transmissions for AM General applications, covering civilian Hummer H1 models and select military and utility vehicle variants.
