The medium duty Aisin AS69RC six speed automatic transmission is available in Ram 3500 models equipped with the optional High Output 6.7L Cummins Turbodiesel, which peaks at 930 lb-ft of torque for the 2018 model year.
Chrysler's 68RFE comes standard in all 6.7L Cummins equipped Ram Trucks (non-H.O.). The six speed automatic transmission is one of three transmission options for the current Ram 2500/3500 HD.
Ram Trucks remains the last of the Big 3 automakers to offer a manual transmission in their heavy duty trucks. For owners who prefer a manual trans, the Mercedes G56 is available in both 2500 and 3500 models. However, it comes at the price of a severely detuned 6.7L Cummins.
While the engine's share the same nominal displacement, that is where the similarities end between the 6.7L Cummins I-6 and 6.7L Ford V-8.
Dodge 8.0L Magnum V-10 engine specs and a comparison between the V-10 and Cummins turbodiesel. The V-10 was available through the 2003 model year before being replaced by the Hemi engine in Ram 2500 and 3500 models.
Cummins 4BT specifications, history, and information. The 4BT is more-or-less a 4 cylinder version of the 6BT Cummins, featuring the same bore and stroke but with 2 absent cylinders. The engine is widely popular in diesel conversions, particularly on smaller vehicles such as 1/2 ton pickups, Jeeps, and custom crawlers.
Introduced in 2014, the EcoDiesel powered Ram 1500 features superior fuel economy without sacrificing the capability that is to be expected from a fullsize pickup.
Eight forward speeds contribute to the EcoDiesel's impressive fuel economy. Designed by ZF, the TorqueFlite 8 transmission is manufactured by Chrysler under a licensing agreement.
