Adaptive Shift Strategy

Adaptive shift strategy is comprised of the following:

• Shift Energy Management - this function involves reducing or increasing engine output torque during shifting.
  • Reduces excessive energy of the friction packs
  • Increases transmission service life
  • Improves shift quality
  • Unique shift schedules are selected based on vehicle operation conditions and environmental conditions
  • Trailer towing mode
• Pressure Modulation - this function monitors the hydraulic pressure in a shift. This pressure must be matched accurately to the transmission input torque to better provide shift comfort.
• Shift Quality Adapts - is used to provide a higher quality and consistent shift feel. Monitoring and adapting shift pressures and shift energy, to overcome hardware variability over time, will achieve this.
• The TCM has the ability to control the engine output torque during the shift, synchronized with the operation of the transmission clutches.
• Trailer towing mode uses a different shift and converter map. This new map reduces the number of gearshifts when towing, climbing steep hills and while driving at higher altitudes.
