2023 RAM 2500 Aisin, Allison, or ZF Transmission?

The next 2023 RAM 2500 will introduce a couple of important upgrades. However, the biggest mystery is the new transmission. And while the rivals are already offering a 10-speed automatic transmission, RAM still provides a 6-speed automatic transmission. RAM will deliver a new gearbox option, and you can find a lot of rumors regarding this category.

Whatsoever, the choice has come down to Aisin, Allison, and ZF transmissions. Of course, we are talking about the diesel powertrain option. Without further ado, here’s everything you need to know about the new RAM 2500 truck and its new transmission.

Aisin Transmission – Is This the End?

The current RAM 2500 is using the Aisin transmission. However, RAM is seriously considering dropping this option from the lineup. As we said, the best models in the segment are already using a 10-speed automatic transmission. The Aisin is only available with six speeds.

At this moment, RAM 2500 truck offers an optional 6.7-liter Cummins turbodiesel engine. Thanks to that, this model generates 400 horsepower and slightly above 1,000 lb-ft of torque. This combination provides 31,000 pounds of towing capacity. However, the new transmission will happen, so RAM 2500 model will get an even better capability.

RAM 2500 With Allison Transmission?

To this day, it seems like the most likely outcome for the 2023 RAM 2500 is the new Allison transmission. Right now, Chevrolet and GMC are offering Allison transmission with Duramax diesel engines. The Duramax powertrains are producing from 250 horsepower to 550 horsepower. Even the torque ratings are ranged from 450 lb-ft to 1,050 lb-ft. The upcoming RAM 2500 should provide a new Allison gearbox, which will be the biggest upgrade.

The Allison transmission is present for over a century. It is an automatic transmission that is very reliable and durable. It provides improved capability and it also has less maintenance. Shifting gears is smoother, so Allison transmission will provide more horses, more torque, and better ride quality. The most reputable reports are writing about the new RAM 2500 and 9-speed automatic Allison gearbox.

What About 8-speed Automatic ZF Transmission?

The 2023 RAM 2500 heavy-duty truck offers a gasoline 6.4-liter HEMI V8 engine. This engine is now supported by a ZF 8-speed transmission. Another rumor is that the optional diesel engine will get the same ZF gearbox. This is a less likely outcome, in our honest opinion. Anyway, the choice comes down to either Allison or ZF, because Aisin transmission will be no longer available. This setup also provides a hydraulic torque converter. Made by Germans, the ZF transmission is extremely reliable.

This gearbox will continue to power the gasoline V8 HEMI engine, but Ram will surely provide new transmission for the Cummins diesel powertrain. Other characteristics of the newest ZF automatic 8-speed automatic transmission include adaptive shift mapping and enhanced shift comfort. Moreover, automatic power-shifting is available, which will significantly improve the vehicle’s acceleration. Because of the new twin damper lock-up converter and oil cooler, the transmission weighs less than most popular gearboxes.
