Many different factors affect transmission longevity, including maintenance, lubrication and circumstance. How knowledgeable are you on this topic? Take this quiz and find out!

# Which of the following statements is true?

Factors such as maintenance and build quality play a role in transmission longevity. Lubrication and heat are also parts of the equation, as are circumstance and fate. It's a heady mix but it can be predicted to some extent, factoring out accidents, system failure, driver input and unlucky thrust washer metallurgy from the factory.

# True or False? Factors affecting transmission longevity are often related to maintenance.

Simply put, factors affecting transmission longevity are often related to maintenance.

# Which of the following statements is true?

While manual transmissions generally require less maintenance and attention than automatic ones do, they're both still subject to the same issues and physical laws.

# True or False? Manual transmissions shift automatically with the aid of a complex hydraulic circuit that uses fluid and pressure to apply and release clutches based on mechanical, hydraulic and electronic inputs.

Automatic transmissions shift automatically, as the name implies, with the aid of a complex hydraulic circuit that uses fluid and pressure to apply and release clutches based on mechanical, hydraulic and electronic inputs.

# Which of the following statements is true?

An automatic transmission is essentially a large and complex hydraulic circuit. Each design creates a different circuit, but each works in what amounts to the same fashion.

# Which scientist defined the primary physical law behind the automatic transmission?

The primary physical law behind the automatic transmission was defined by the French scientist Blaise Pascal more than 300 years ago. He discovered liquids could readily transfer force because they were non-compressible. More importantly, force moving via a liquid could be transferred in a more flexible manner.

# True or False? When it comes to transmission use, severe use is defined as more than 20 percent use in heavy city traffic with ambient temperatures above 80 degrees Fahrenheit (22.2 degrees Celsius).

Most experts feel severe use warrants a recommended 15,000-mile (24,140-kilometer) fluid and filter change interval. Severe use is defined as more than 50 percent use in heavy city traffic with ambient temperatures above 90 degrees Fahrenheit (32.2 degrees Celsius).

# Which of the following statements is true?

Experts recommend changing transmission fluid whenever there is an indication of oxidization or contamination.

# True or False? Changing transmission fluid is as simple as changing engine oil.

Changing transmission fluid is not as simple as changing engine oil and should be handled by a service technician or someone with a thorough understanding of transmissions.
