8L45 Frequently Asked Questions
Is the 8L45 a good transmission?

What is the difference between the 8L45 and the 8L90?
The 8L45 is a medium-duty transmission for V6 engines, while the 8L90 is a heavy-duty transmission for V8 engines. The 8L45 is lighter, more compact, and more fuel-efficient, making it suitable for smaller, high-performance vehicles.

The 8L45 is rated to handle up to 400 lb-ft of engine torque, making it ideal for performance driving with V6 engines. It offers excellent power transfer, smooth shifts, and fuel efficiency.
How much does an 8L45 transmission cost?
A replacement 8L45 transmission can be quite expensive, ranging anywhere from $1,700 to $6,000. A remanufactured 8L45 transmission, however, is a more cost-effective solution, typically priced significantly cheaper than new, offering a like-new transmission at a fraction of the cost of a new unit.
8L45 History & Information
The GM 8L45 transmission was developed to meet the needs of modern, high-performance vehicles, offering a refined balance of power and fuel efficiency. It replaced older 6-speed and 5-speed units, delivering smoother shifting, improved performance, and better fuel economy. With its 8 forward gears, the 8L45 transmission provides a seamless driving experience, making it ideal for today's high-performance sedans, sports cars, and trucks.
The 8L45 is engineered for GM’s latest V6 engines and is featured in a variety of vehicles, including:
- Chevrolet Camaro (V6 models, 2016–present)
- Cadillac CTS (V6 models, 2017–2019)
- Chevrolet Colorado (2015–present)
- Chevrolet Traverse (2018–present)
- Buick Enclave (2018–present)
- GMC Canyon (2015–present)
- GMC Acadia (2017–present)
- Chevrolet Blazer (2019–present)
- Cadillac XT5 (2017–present)
Designed for both performance and efficiency, the 8L45 is a more compact and fuel-efficient option compared to its predecessor, the 6L80 transmission, which was built for V8 engines mainly in trucks like the Chevrolet Silverado 1500 and GMC Sierra 1500.
The 8L45 shares components with the 8L90 transmission but is designed for medium-duty applications, providing a more compact and fuel-efficient design. It improves upon the reliability and performance of its predecessors by offering a better performance-to-weight ratio, enhanced shifting algorithms, and a more efficient powertrain overall. This makes the 8L45 a strong performer for both quick starts and highway cruising.
The 8L45 is part of GM's 8-speed transmission family, which includes earlier models like the 6L80, 6L50, and 6L90 transmissions. The 6L80, a 6-speed transmission, was used in GM's V8-powered vehicles, including trucks, SUVs, and the Chevrolet Corvette (2006–present). The 6L50 was a more compact 6-speed designed for less demanding applications, while the 6L90 was a heavy-duty 6-speed transmission for larger V8 engines. Prior to these, GM used the 4L60 and 4L80, 4-speed transmissions, which laid the foundation for later developments like the 6L80 and 8L45. The 4L60 transmission was commonly found in GM's trucks and SUVs from 1993–2007, while the 4L80 was a heavy-duty version for larger, more powerful vehicles, available from the early 1990s until 2007.
