Regularly check and replace the transmission fluid according to the manufacturer's recommendations. This is crucial for maintaining the proper functioning of your transmission.

Be gentle when shifting gears, avoiding harsh acceleration or sudden stops. This will prolong the life of your transmission.

If you start to notice any strange noises or shifts while driving, have your transmission checked by a trusted mechanic as soon as possible. Catching any issues early can prevent costly repairs down the line.
