The purpose of the transmission is to transfer the power generated by the engine to the drive axle and wheels by using different gears. A car’s engine rotates within a fixed range of speeds, generally from 600 to 7,000 revolutions per minute (rpm) for most passenger vehicles. The vehicle’s wheels typically spin from 0 to 1,800 rpm, so the transmission uses different gears with specific ratios to match the most efficient use of engine power for the vehicle’s speed.

Like other vital automotive fluids, transmission fluid deteriorates over time. Hard use — such as frequent stop-and-go city driving, hauling heavy loads, trailer towing — will accelerate the deterioration. That kind of driving raises the transmission's operating temperature, and heat puts more strain on the transmission and the fluid. Unlike engine oil, which is primarily a lubricant, transmission fluid serves as both an oil and a hydraulic fluid that helps facilitate gear shifts, cools the transmission and lubricates moving parts.

While you’re there, let us perform an A thru S® Courtesy Check, which includes a visual check of the following items:

• Engine air filter
• Brake fluid
• Power steering fluid
• Automatic transmission fluid
• Coolant/antifreeze
• We'll also walk you through your vehicle manufacturer's
  recommendations for replacing these vital fluids and filters.

With a Car Repair Service oil change, or any other service, you’ll receive an A thru S® Courtesy Check. We’ll look inside, outside, under the hood and underneath the car, then explain the findings and give you a written report.
