What brand is the transmission of the Volvo S90?

[ZoeLynn]

The transmission of the Volvo S90 is from Aisin, a world-renowned professional developer and manufacturer of automotive automatic transmissions established in 1969. In the field of automotive automatic transmissions, Aisin's products hold the highest market share globally. The Volvo S90 comes standard with an 8-speed automatic transmission, which can quickly respond to changes in engine speed, ensuring smooth gear shifts. The multiple switchable gear ratios mean the engine's torque and power range can be effectively utilized. Two of these gears are overdrive gears, which can save fuel when driving at a constant engine speed. Manual gear selection is also available, and the current gear can be displayed on the screen in front of the driver. When using the transmission of the Volvo S90 in daily driving, the following points should be noted: Do not delay changing the transmission oil for too long. Although many models now come with maintenance-free transmission oil, maintenance-free does not mean it never needs to be changed. Prolonged failure to change the transmission oil can lead to damage to internal components such as bearings and the housing. Avoid coasting in neutral for extended periods. While driving manual transmission vehicles, many experienced drivers may coast in neutral, but for automatic transmission vehicles, this can cause the transmission to overheat and may result in a jolt when shifting back into Drive (D) mode. Never shift into Drive (D) or Reverse (R) before the vehicle has come to a complete stop. Many drivers, aiming to demonstrate smooth operation, shift directly into reverse while the vehicle is still moving, which can significantly damage the transmission gears and, over time, lead to issues like gear grinding. Do not frequently climb steep slopes in Drive (D) mode. When facing steep inclines, automatic transmission vehicles can overheat due to high load or may shift up too early, resulting in insufficient climbing power. In such cases, using manual mode to limit the gear to a lower speed or switching to sport mode can help protect the transmission. Avoid long-distance towing. If an automatic transmission vehicle breaks down, it should be transported using a flatbed tow truck with the vehicle in Neutral (N) mode, rather than being towed directly with a tow rope or similar methods.
