The transmission’s main function is to distribute the correct amount of engine power to the wheels by changing gears up and down according to your driving speed.
While today’s automobile manufacturers use five- and six-speed manual transmissions less frequently, the number of gears in automatic transmissions has jumped from four to as many as ten! Some gearboxes are controlled with paddle shifters on the steering column to recreate the experience of driving a stick shift.
Transmissions are designed to last a long time, but they will eventually wear out and need repair.
Prolong the life of your transmission by having your transmission fluid replaced on schedule. More than a lubricant, this fluid contains detergents and other additives to protect your transmission. Old fluid does not protect as well as new fluid.
