First, we’ll look at the difference between Allison and Aisin transmission in terms of performance. Check out their specs below to compare gears, weight, and sizing.
Aisin Seiki Six-Speed AS68RC (Dodge Cab and Chassis)
Allison 1000 (Chevrolet and GMC)
Generally, transmissions with numerically higher first gears are more adept at getting a truck rolling, while transmissions with numerically lower sixth gears offer higher fuel-efficiency ratings. If you want to get down to brass tacks, the Aisin is heavier but more economical based on the numbers, and also delivers more pulling power to get the truck moving. The size of a torque converter can impact fuel economy; however, larger torque converters are more durable and provide smoother gear shifts. Both offer a 12.2-inch torque converter, so they’re evenly matched in that regard.
Who makes Aisin transmissions? Aisin automatic transmissions are built by Aisin Seiki and Aisin AW. Toyota Motor Corporation and Aisin Seiki are shareholders of Aisin VW — the largest producer of automatic transmissions in the world. Aisin AW supplies 55 automotive manufacturers, from Ford and Nissan to MINI and Volvo. Aisin Seiki manufactures automatics for heavy-duty vehicles, while Aisin AW does the opposite — they manufacture for light-duty vehicles. Read on to learn more about three of the most commonly discussed models, the difference between Allison and Aisin transmission, and how to identify an Aisin transmission.
Chrysler used this machine for 2007 model-year work trucks along with the 6.7 Cummins turbodiesel engine. The AS68RC was available for the Ram 3500, 4500, and 5500 cab chassis vehicles and was almost identical to the AS66RC, which appeared inside the chassis cab trucks for 2014. It’s known as the A465 when not installed inside a 2007- 2013 Dodge and is identified by its three driving clutches, two brake clutches, a one-way sprag clutch, and three planetary gear assemblies.

For the 2013 model-year, Dodge introduced the AS69RC as a replacement for the AS68RC transmission. It was available for the Ram 3500HD, as well as Ram 4500 and 5500 chassis cabs. The AS69RC included a number of upgraded parts, such as a larger input shaft, a new torque converter design, and a deleted F1 sprag clutch for first and reverse gears. The AS69RC is also identifiable by its unique Tow/Haul Mode. Drivers can simply press a button on the center stack to lock out overdrive gears and get the best possible performance from the Cummins Smart Diesel Exhaust Brake.

Introduced for the 2014 model-year, this transmission replaced the AS69RC and was offered for Ram 3500, 4500, and 5500 cab chassis models. It included a compact gear train with three clutches, two brakes, and a new shift control algorithm. The Transmission Control Module allowed it to temporarily turn off the exhaust brake during shifting, and the enhanced Tow/Haul Mode gave it a stronger downshift cycle for commercial operations.

One of the most common Aisin transmissions is the Aisin AS66RC, which can be found on RAM Cab Chassis trucks that employ a 6.4L V8 engine. The Aisin AS69RC, another popular offering, is paired with RAM Cab Chassis models that employ the 6.7L Cummins® diesel engine. It replaced (and is directly based on) the AS68RC from older Dodge RAM Cab Chassis trucks.
