The objective of this work was to investigate the capability of 15W-40 lubricants to meet the frictional requirements of military powershift and automatic transmissions and, if required, provide a procedures for selecting acceptable lubricants for application under the MIL-L-2104D specification. A variety of lubricants were evaluated were evaluated during this test program. The oils included DDA C-3 pass and fail reference oils, five MIL-L-2104D oils, and two special experimental oils. Four of the nine test lubricants were 15W-40 oils. The test lubricants were evaluated for torque, sliptime, and discplate were using a modified DDA C-3 friction test. Various bronze frictions materials used extensively in Allison combattactical automatic and powershift transmission were tested under varying operating conditions.
