With what type of lock-up will the transmission enter lock up at any time—even in first range—as long as certain criteria are met?

Explanation:
Lock-up control in torque converters can be engaged or modulated, and modulated lock-up is designed to vary how the clutch engages based on operating conditions. With modulated lock-up, the clutch can be engaged progressively or slip slightly to match engine load, speed, and throttle input. This means it can lock up even in the lowest gear (first range) when specific criteria are met, providing better fuel economy and smoother operation without forcing full lock-up at all times. The other terms describe more fixed or non-dynamic approaches and don’t capture this adjustable behavior.
