Inspection and Analysis of Failed Transmissions

摘要

Three Allison Transmission Incorporated (ATI) 2500-SP transmissions failed in service OCONUS, and were shipped to US Army TARDEC Fuels and Lubricants Research Facility for tear down and inspection. Each transmission was completely disassembled and components inspected and rated in an effort to determine the overall cause of failure. Used fluid samples were collected from each transmission and analyzed to classify the types of fluid that were in use during failure. Upon completion of work, a parts inspection meeting was hosted at Southwest Research Institute for representatives from TARDEC and ATI.
