The best place to find information on repairing transmissions is a trusted vehicle mechanic shop that specializes in a specific type of car. Online sitescan give a rough estimate of the costs to fix transmissions, but are not accurate if the user does not know the specific problem with their vehicle's transmission.
The transmission of a vehicle refers to the system of gears that provide speed and torque conversions from the motor to the wheels. An automobile's internal combustion engine goes through thousands of revolutions per minute, so the transmission gearbox converts these revolutions into slower, more powerful revolutions that power the wheels. Transmissions can either be manual or automatic, which means that either the driver needs to manually shift gears with a gear stick or the vehicle does it automatically.
A vehicle's transmission is one of the most complicated pieces of equipment in the machine. For this reason, if something in the transmission goes wrong it is not always easy for an untrained eye to diagnose the problem. When transmissions malfunction, untrained individuals should search for a mechanic that specializes in their specific type of car. Some mechanics offer over-the-phone consultations which will help to determine the problem with the vehicle and the estimated cost of repair.
