AB  - This research details the approach to justify optimum thermal conditions for a vehicle transmission
unit. This approach is based on the integrated criterion which comprises aggregated energy expenditures to
warm up a transmission reduction gear and to overcome forces of mechanical and hydraulic friction inside its
components. Thermal working conditions of a unit shall be considered optimum when energy expenditures are
the lowest. Justification and development of technologies to provide optimum thermal conditions of a unit shall
be based on comparison of optimum temperature values and temperature values of transmission oil
stabilization. If optimum temperature exceeds stabilization temperature, then additional heat sources shall be
used if it is lower then heat shall be transferred to other units. Analysis of optimum thermal conditions of the
KAMAZ transmission shows that the transmission unit has an excessive thermal potential. Optimum
temperature exceeds stabilization temperature by 5 K, so, excessive thermal energy must be transferred.
