It is capable of handling up to 900 lb-ft of torque. The 6L90 transmission has a reputation for being reliable and durable. However, like all mechanical components, it is subject to wear and tear over time.
The average life expectancy of a 6L90 transmission is around 150,000 miles. However, this can vary depending on how the transmission is used and maintained. Proper care and maintenance are key to prolonging the life of any transmission, but this is especially true for the 6L90.

What Years Did Gm Use the 6L90 Transmission?
The 6L90 transmission was introduced in 2007 and is still in production today. It is GM’s first six-speed automatic transmission, and was designed for use in rear-wheel drive vehicles with a V8 engine. The 6L90 transmission has been used in a variety of GM vehicles, including the Cadillac CTS, Chevrolet Camaro, Chevrolet Corvette, and GMC Sierra.
Is the 6L90 an Allison Transmission?
The short answer is no, the 6L90 is not an Allison transmission. The two transmissions are often confused because they both have six gears and are used in heavy duty applications, but they are very different internally.
Allison transmissions use a torque converter to couple the engine to the transmission, while the 6L90 uses a clutch pack.
The Allison also has full manual control, meaning you can shift it without using the gas pedal, while the 6L90 requires you to be on the throttle to upshift and downshift. Finally, Allisons use planetary gearsets while the 6L90 uses helical gears. So why might someone think the 6L90 is an Allison?
Well, GM has used both transmissions in their heavy duty trucks for years (Allisons in Duramax trucks and 6L90s in Gas trucks), so it’s easy to see how the confusion could arise. They’re both built to handle a ton of abuse and last for hundreds of thousands of miles with proper care, so they make ideal choices for hard working vehicles.
