Dependable Vehicles Require Maintenance

Transmission Repairs

There are two types of transmissions: manual and automatic.  If you have a manual transmission, you have to shift the gears yourself using a gear shifter and clutch pedal in tandem.

With an automatic transmission, the gears shift themselves.  This is done using a system thatís powered by hydraulic pressure.  A shift valve controls each shift of the gears and shifts depending on speed, the road, and load conditions.

The Manual Transmission

Manual transmissions require the use of a clutch to apply and remove engine torque to the transmission input shaft. This happens gradually so that the car can be started from a complete stop.

The manual transmission encompasses a variety of active parts:

  • Transmission Gears
  • Transmission Oil
  • Gear Shift Mechanism
  • The Clutch
  • The Clutch Plate
  • The Flywheel
  • The Clutch Pedal, Cables and Levers
  • Hydraulic Clutch

Automatic Transmissions

An automatic transmission is much easier to use. Unlike a manual transmission, you don't have to use a clutch pedal or gearshift lever. The automatic transmission does the work all by itself.

Immensely complex, at its simplest automatic transmissions automatically change to higher and lower gears with changes in the car's speed and the load on the engine. These also take into account the amount of pressure placed on the gas pedal, and shift accordingly to increase the engines RPMís as necessary to reach the required speed.

Automatic Transmission Essentials

An automatic transmission consists of the following:

  • Torque Converter
  • Brake Bands
  • Transmission Fluid

Flush Transmission ~ The transmission changes gears from the pressure of the weight of the transmission oil. When the oil becomes old, it becomes thin, not providing adequate pressure, which wears out the cluthces. Changing the transmission oil every year prevents damage and expensive rebuilding.
