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.
