Technician A says that an Allison output retarder functions independently from engine rpm during braking cycles.Technician B says that Allision output retarder efficiency is not influenced by the transmission ratio during a braking cycle.Who is correct?

Question

Quizplus · Accepted Answer

Allison output retarders are hydraulic devices that use the transmission oil to create resistance to rotation, which slows the vehicle down. The retarder is independent of engine rpm and transmission ratio, so it can be used to slow the vehicle down regardless of the engine speed or gear that is selected.
