Information and specifications related to the Aisin model A466ND automatic transmission found in the 5.0L Cummins powered Nissan Titan XD.

2013 Ram 3500 HD

Chrysler 68RFE 6 Speed Automatic

The Chrysler 68RFE six speed automatic transmission made its debut simultaneously alongside the 6.7L Cummins Turbodiesel midway into the 2007 model year. The transmission has since earned a reputation far greater than any of Chrysler's previous automatic transmission designs, although it remains second to Ram's Aisin offering behind H.O. Cummins models.

Mercedes G56 manual transmission

Mercedes Benz G56 Six Speed Manual

The last of the handshakers, Ram remains the last of the Big 3 to offer a manual gearbox with their diesel option. While ordering a Ram 2500/3500 with a manual trans comes at the expense of a greatly detuned Cummins Turbodiesel, one can only commend Ram for continuing to offer the G56 in its heavy duty pickup line.

GMC Canyon

General Motors 6L50 Hydra-Matic Six Speed Transmission

Found in the 2.8L Duramax equipped Chevrolet Colorado and GMC Canyon (and gas engine applications since 2006), GM's six speed automatic features a relatively low first gear ratio and tall 0.67:1 overdrive gear

TorqShift equipped Ford Super Duty

Ford TorqShift 5R110W

Ford's "TorqShift 5" five speed automatic transmission, officially the 5R110W, made its debut with the 6.0L Power Stroke for the 2003 model year. Where the 6.0L left much to be desired in the early years, the TorqShift became an instant favorite as a result of its quick, crisp shift characteristics and has since earned a positive reputation in terms of reliability and durability.

ZF 6 speed manual transmission

ZF 6 Speed Manual (S6-650 & S6-750)

The ZF S6-650 and S6-750 manual transmissions can be found in various Ford (7.3L, 6.0L, 6.4L Power Stroke) and General Motors (6.6L Duramax) applications. The six speed gearbox represents the last manual transmission offered by both companies.

ZF 5 speed manual transmission

ZF 5 Speed Manual (S5-42 & S5-47)

If you were to call the ZF 5 speed bulletproof, you wouldn't be wrong - it takes a lot to kill one of these units. Unfortunately, the hydraulic clutch system and associated components has a tendency to produce a false sense of transmission troubles. An abundance of these units remain in service behind 7.3L Power Stroke diesel equipped Ford pickups.

New Venture NV5600 manual transmission

New Venture NV5600 6 Speed Manual

New Venture's NV5600 six speed manual transmission was used as a heavy duty alternative to the NV4500 for the 1999 to 2005 model year H.O. Cummins turbodiesel.

New Venture NV4500 & NV4500HD 5 Speed Manual

The venerable NV4500 was produced by New Venture Gear, a partnership between Chrysler's New Process Gear and General Motor's Muncie drivetrain divisions. As such, the transmission is found in various Dodge and GMC/Chevrolet applications between 1992 and 2005 model years.

Ford 4R100 automatic transmission

Ford 4R100 Four Speed Automatic Transmission

Ford planted its 4R100 four speed automatic transmission in 1999 to 2003 model year Super Duty trucks equipped with the 7.3L Power Stroke diesel, amongst other applications. The transmission was essentially an upgraded version of the E4OD and would be replaced with the introduction of the 6.0L Power Stroke, TorqShift transmission duo.

2005 Dodge Ram 3500 Cummins turbodiesel

Dodge 48RE Four Speed Automatic Transmission

The 48RE from Chrysler represents an improvement over the previous 47RE, although it seemed to struggle to keep up with the Cummins' growing power and torque ratings.

1997 Dodge Ram 3500 Cummins Turbodiesel

Dodge 47RH and 47RE Automatic Transmission

The Chrysler 47RH ("hydraulic") and later 47RE ("electronic") automatic transmissions are not particularly popular - in stock form, that its. Let's face it, anything can be built to handle abuse. The problem with the 47RH/47RE is that the transmissions were severely under rated for the power and torque characteristics of the venerable Cummins turbodiesel.

GETRAG G360 manual transmsision

GETRAG G360 5 Speed Manual Transmission

The GETRAG G360 five speed manual transmission was used in the 1st gen Cummins, 1989 to 1993 model years. It predated the more popular New Venture NV4500 transmission and is much less popular amongst owners. The GETRAG's biggest downfall is that replacement parts are hard to find and relatively expensive.
