Ram is getting the Allison Transmission for 2023?

For a long time, Ram and Cummins have been considered a perfect couple. With Ram’s design and technical solutions backed by the class-leading torque offered by Cummins diesel engine, Ram HD models are usually considered the best in this class. However, this pickup could become even better in the next year. According to rumors, we would see not just a perfect couple, but a perfect trio, in the scenario where Ram is getting the Allison transmission for 2023.

This still has to be officially conferment but it’s not a secret that the transmission upgrade has been in talks for years. Namely, the current 6-speed unit is very good but it starts to feel old when compared to rivals, which all come with 10-speed units. With such an upgrade, there’s no doubt that the Ram HD models would become even better.

Is the Current 6-speed Automatic Transmission Really That Bad?

In many reports, you can see how experts talk about Ram getting the Allison transmission but let’s talk about the current gearbox first. The current Ram HD comes with two transmission options, depending on the engine choice. Gasoline models use an 8-speed unit from ZF, while diesel models use a 6-speed automatic transmission from Aisin. While ZF’s unit is undoubtedly the most refined transmission among all transmissions that are used on the pickup market, it’s not sturdy enough to deal with all that torque from the diesel engine. That’s why Ram still uses the 6-speed Aisin gearbox.

The Japanese transmission is far from bad and its quality definitely isn’t the reason for the change. It is sturdy, efficient and decently refined. The actual reason for the change is the fact that it’s becoming outdated, which is the thing that makes Ram less competitive. Namely, both Silverado HD and Ford Super-Duty models use 10-speed units, which looks like a significant advantage in the eyes of many potential buyers.

Rumors about Ram HD getting a new transmission have been around for years and the latest reports finally suggest that this could actually be more than rumor. Namely, a few sources suggest that this could happen in 2023. We would see the Aisin transmission replaced with the Allison unit. The Allison transmission features 10 gears and already proved itself as a capable unit, considering that it’s been in Silverado HD models for a while.

The benefits from the new transmission would be various, starting from the refinement. Besides more refined operation, more gears and different rations would also make a positive impact on fuel economy, as well as on the overall performance, including towing capacity. After all, we have already seen aftermarket conversions that proved that the Allison transmission works great in a combination with a 6.7-liter Cummins turbodiesel.

The Ram is getting the Allison transmission for 2023, according to the latest reports and from what we can see, the new gearbox would be reserved for the diesel version. The gasoline model, which uses a good-old 6.4-liter HEMI V8 engine with 410 horsepower and 429 pound-feet of torque, will carry on with an 8-speed transmission from ZF.

On the other hand, the 6.7-liter inline-six turbodiesel from Cummins would get a 10-speed Allison transmission. This engine is available in two variants. The base one is good for about 370 horsepower and 850 pound-feet of torque, while the high-output version puts out around 420 horsepower and 1.075 pound-feet of torque.
