Driving the Wheels
There are many variations in how transmissions work. Generally, there are rear wheel drive, four wheel drive and front wheel drive systems. In rear wheel drive vehicles, the drive shaft comes out from the transmission and spins gears in the differential to cause the spinning to change its power at a right angle in the final drive of the wheels. This can be utilized with two or four-wheel drive systems.
A transaxle takes power from an engine to cause a front wheel drive car to move. Normally, a sideways mounted engine provides power to the transaxle which is usually directly connected to the final drive and wheels.
In manual transmission, you control the gear-ratio between engine and wheels with a stick, lever or push-buttons. A manual transmission eliminates some moving parts and therefore is easier to maintain (and usually less-expensive, too).
In an automatic transmission, the clutches and bands control the planetary gear sets which glide along paths as the flow of power shifts from low gear to higher gears. This is usually monitored by a computer which causes the clutch plates and clutch disks to interact within the drum. Oil pressure activates the sequence which determines the proper gear ratio.
In all of these systems there are oodles of things that can go wrong. Generally, the parts just wear out. Salt and dirt accumulation, bad bumps, and collisions often contribute to early transmission system failure. At Hanover Transmission, we get to the heart of why a transmission failed and what it takes to make your car run confidently again.
The More You Know the More You Trust Hanover Transmission
Obviously there is much more to the way the mechanisms work within the transmission, but when we talk to you, we want you to have a general background in how your car works. The more you know, the more you can trust Hanover Transmission to work for you.
