The strange noises in driving gears, slow shifting, violent shaking below the car, and gear slippage are making it hard to drive your vehicle. Your Nissan Altima transmission is the vehicle component responsible for your ability to shift gears while driving. When a part of it is not working, you cannot shift efficiently. For example, a bad torque converter can lead to strange noises in driving gears and a bad clutch can lead to violent shaking below the car. Until the 2013 model release, this vehicle has a 4-speed automatic transmission, a 5-speed Altima manual transmission, and a 6-speed manual transmission. The Altima's manufactured between 2002 and 2006 also have the 5-speed manumatic transmission, a type of automatic transmission that allows the driver to better control the gears. The 2013 Altima has a continuously variable transmission (CVT) and this type has infinite gear ratios that drivers can seamlessly change.
