includes parameters for adjusting shift points

• A. Auto Shift Speed
• B. Shift Points
• C. Shift Pressure
• D. Auto TCC

Answer: (A)

The idea being tested is how automatic shift timing is controlled. In an automatic transmission, when the car accelerates, the TCM decides not only which gear to be in, but how quickly to move to the next gear. Auto Shift Speed is the setting that determines how rapidly a gear change is completed in automatic mode. So, increasing Auto Shift Speed makes shifts happen faster, which effectively alters the practical shift points you feel during driving. It’s the knob that directly tunes how aggressively the transmission shifts, changing when gears are engaged under load.

Shift Points would be the literal thresholds at which a shift should occur, but in many tuning interfaces those thresholds are handled or influenced by the shift timing parameter as well. Shift Pressure affects how strongly the clutch packs engage during a shift, influencing feel and durability but not the timing of when the shift happens. Auto TCC controls the torque converter lockup behavior, which is a different aspect of power transfer and not the gear-change timing.
