What type of transmission does the Chevrolet Equinox use?

[OHolden]

The Equinox is equipped with a 9-speed automatic transmission. Below are the relevant details about the transmission: 1. Gear ratio setup: The General Motors 9-speed automatic transmission features only two overdrive gears, with reduced differences between the lower gears. This design aims to ensure smoother gear shifts. The smaller gaps between gears in the 9-speed automatic transmission result in smoother transitions, allowing the engine to operate in the optimal gear regardless of engine speed or vehicle speed. Additionally, the new 9-speed automatic transmission includes a start-stop function, contributing to reduced fuel consumption. 2. Shift control: The shift control module determines the optimal shift timing by receiving information from the brake pedal, vehicle acceleration, throttle position, gradient, and whether a trailer is connected. The 9AT also features automatic grade braking, which selects lower gears during downhill coasting or braking to maintain the desired vehicle speed. This utilizes engine braking to prevent unnecessary acceleration, reducing the need for brake application during downhill driving. 3. Active transmission fluid management system: The hydraulic system of GM's new 9-speed automatic transmission is electronically controlled, ensuring the required pressure and transmission fluid volume under various operating temperatures for optimal lubrication and cooling. The valve body side cover acts as an internal expansion tank, storing excess transmission fluid when not needed and delivering it to the oil pan via pressure when demand increases. Furthermore, the transmission fluid used in the 9AT does not require replacement under normal driving conditions, providing convenience for long-term maintenance.
