There are many different types of automotive transmissions in service. Some are the manual shift variety a.k.a. “manual transmission” and others shift automatically a.k.a. “automatic transmissions.” Some transmissions (manual or automatic) are integrated with the vehicle’s differential and are known as “transaxles” and are used typically in front-wheel-drive vehicles. Regardless of the shifting method, the transmissions purpose is to transfer power or torque produced by the engine, through the Drive-Shaft to the wheels of your automobile and propel the vehicle forward. The task is accomplished by leveraging available power through multiple stages of gears and/or clutches.

While the process may sound simple enough, your car’s transmission is a very complex component, consisting of hundreds of parts. There are a myriad of gear clusters, bearings, races, input and output shafts, retaining clips, seals, gaskets, springs, and clutch packs in automatic transmissions. Since transmissions constantly operate under a load and have many points of internal friction, it is very important to ensure the parts are well-lubricated and kept clean with regular oil and filter changes.

Transmission Fluid Breaks Down
Transmission fluid is vital to the health of your car transmission. Considerable heat may build inside your transmission as the transmission fluid attempts to cool and lubricate friction points and moving parts while under various operating conditions. Small metal and fiber particles can also accumulate and result in accelerated wear and tear. Regular transmission flushing alleviates the effects of wear and tear.

Signs Of Transmission Issues
Help cut the cost of transmission service by taking care of small problems before they worsen. If you notice any of the following signs, schedule an appointment at your nearest Tires Plus for a service or repair before your transmission fails

• Transmission slips or vehicle does not move forward when accelerator pedal is depressed
• Rough shifts from gear to gear
• Thud or clunking noises when the transmission shifts gears
• Long pauses between shift points
• Transmission fluid leaking reddish fluid under vehicle
• Transmission warning light on your car or vehicle’s instrument cluster

How Often Is Transmission Service Required?
Always refer to your car owner’s manual for factory recommended maintenance intervals. The average vehicle needs to get a transmission fluid flush every 30,000 to 50,000 miles, with some manufacturers suggesting a service life of up to 100,000 miles. But, a lot will depend upon your driving habits and requirements, causing the fluid to break-down at an accelerated rate – requiring more frequent service intervals.
