Is a manual transmission less expensive to maintain than an automatic?

According to, the cost of maintaining a stick shift system is less expensive than that of an automatic. The idea that a manual transmission is more reliable may stem from the fact that they are usually cheaper to repair. Automatics have so many more intricate parts and complex functions that have the ability to fail. Part of what may make a manual transmission more reliable than an automatic is the sheer level of simplicity when you compare the mechanics of one to the other.

Additionally, because of all of these complicated mechanic functions and the parts that drive them (no pun intended), an automatic transmission typically costs more to repair. reports about a $500 to $1000 dollar difference in favor of a manual transmission should you need to replace it. And that is when we are talking about mainstream vehicles. The transmission on a luxury vehicle will, of course, run way higher––nearing the $10,000 mark. So the difference may matter less if you are in something like an Aston Martin Vantage or a BMW 2-Series.

Manual transmission fuel economy

In a 2015 article by Consumer Reports, it’s stated that “manual transmissions can deliver better fuel economy and acceleration.” There are a few comparisons between the manual versus the automatic transmission in terms of gas mileage. Some vehicles such as the Mazda3 i and the Chevrolet Sonic saw improved fuel economy with a stick shift. As opposed to their automatic counterparts which fell behind a couple of mpg.

However, this article is a bit dated. While that may have been true for cars in 2015, such is not the case for the newer cars. For example, the 2021 Mazda3 was tested by Car and Driver. The manual transmission version of the 2021 Mazda3 did return better fuel mileage than it is rated for. But it was still behind the automatic transmission in terms of fuel economy by 2 mpg.

The folks at Edmunds also bust the myth that manual transmission vehicles have better fuel economy. Some may think that a manual is more reliable than an automatic transmission. They might make the argument that the fuel economy is better. But this assumption applies only to older models.

However, it’s not as simple as maintenance costs. Because the reliability of a manual transmission can be variable depending on drive style, it’s actually very difficult to say one way or the other. Which is more reliable? In an older car with a skilled driver, it will certainly ring true that a manual is more reliable. However, if the driving is hard on the clutch then the same statement is false––even in a newer car. Overall, there are too many factors and variables. These days, it’s just not prudent to make the blanket statement that manuals are more reliable. Even if they are more fun.
