What factors are considered in automatic transmission shift calibration?

Shift calibration considers: Shift scheduling (when to shift based on throttle and speed for fuel economy vs performance), clutch-to-clutch timing (overlap control for smooth shifts), torque reduction (engine torque management during shifts), adaptive learning (compensating for clutch wear and variation), driver mode selection (comfort, sport, economy maps), temperature compensation (cold start and hot operation), and grade sensing (hill detection for shift strategy). The goal is optimal balance of shift quality, durability, fuel economy, and performance.
