The C6 transmission was introduced in 1966 by Ford Motor Company as the successor to their Cruise-O-Matic line of transmissions. The C6 was Ford’s first three-speed automatic transmission and was designed to be used in high-performance and heavy-duty applications. The C6 was offered in a wide variety of vehicles, from the Ford Thunderbird to the Ford Mustang to the Ford Bronco. While the C6 was eventually phased out in favor of the AOD and AODE transmissions, it is still a popular transmission in classic and hot rod applications. In order to understand the C6 transmission and its various gear ratios, it helps to first understand the basics of a gear ratio.
A gear ratio is the ratio between the number of teeth on a driven gear and the number of teeth on a driving gear. When the driven gear has more teeth than the driving gear, the gear ratio is said to be numerically high. Conversely, when the driven gear has fewer teeth than the driving gear, the gear ratio is said to be numerically low. A gear ratio is important because it determines the amount of torque multiplication that occurs when power is applied to the driving gear. In other words, the gear ratio affects how much power is transmitted to the driven gear.

Understanding C6 Transmission Gear Ratios
The C6 transmission has three gear ratios: 1.52 (1st gear), 1.00 (2nd gear), and 0.67 (3rd gear). The 1.52 gear ratio means that for every 1 turn of the input shaft, the output shaft will turn 1.52 times. This means that the output shaft will rotate faster than the input shaft, resulting in increased torque multiplication. This is beneficial for applications that require a lot of torque, such as towing or hauling heavy loads. The 1.00 gear ratio in 2nd gear is direct drive, meaning that the output shaft will turn at the same speed as the input shaft, resulting in no torque multiplication. This is beneficial for applications that require a lot of power, such as racing.
The Benefits of C6 Transmission Gear Ratios
The C6 transmission’s gear ratios provide a number of benefits. First, the 1.52 ratio in 1st gear allows for increased torque multiplication, allowing the vehicle to get up to speed quickly and easily. Second, the 1.00 ratio in 2nd gear provides direct drive, reducing power loss and providing increased power to the wheels. Third, the 0.67 ratio in 3rd gear provides increased fuel economy, as the engine is not working as hard to drive the vehicle. Lastly, the C6 transmission’s gear ratios are relatively simple, making it easy to maintain and repair.
C6 Transmission Gear Ratios and Performance
The C6 transmission’s gear ratios have a direct impact on a vehicle’s performance. For example, the 1.52 ratio in 1st gear allows for increased torque multiplication, resulting in quicker acceleration. The 1.00 ratio in 2nd gear provides direct drive, resulting in increased power to the wheels. And the 0.67 ratio in 3rd gear results in increased fuel economy, as the engine is not working as hard to drive the vehicle. Additionally, the C6 transmission’s gear ratios are relatively simple, making it easy to maintain and repair.
Tips for Maintaining C6 Transmission Gear Ratios
In order to keep the C6 transmission’s gear ratios in good working order, it is important to perform regular maintenance. This includes changing the transmission fluid and filter every 30,000 miles or so, as well as inspecting the transmission for signs of wear or damage. Additionally, it is important to check the transmission linkage for proper adjustment, as this can affect the gear ratios. If the linkage is not properly adjusted, the transmission may not shift correctly, resulting in an incorrect gear ratio.
Conclusion
The C6 transmission’s gear ratios are an important component of a vehicle’s performance. The 1.52 ratio in 1st gear allows for increased torque multiplication, the 1.00 ratio in 2nd gear provides direct drive, and the 0.67 ratio in 3rd gear provides increased fuel economy. Additionally, the C6 transmission’s gear ratios are relatively simple, making it easy to maintain and repair. To ensure that the C6 transmission’s gear ratios remain in good working order, it is important to perform regular maintenance and check the transmission linkage for proper adjustment.
