Aisin A466ND Transmission Specs & Ratios

The Aisin A466ND debuted in the 2016 model year Nissan Titan XD, transmitting power from a 5.0L Cummins V-8 Turbodiesel. The transmission is similar in weight to and shares ratios with the medium duty AS69RC available in Ram 3500 pickups equipped with the H.O. 6.7L Cummins. At nearly 400 lbs, the transmission is substantially heavier than that of any competitor within the 1/2 ton and 3/4 ton category. The A466ND features an integrated towing mode which, when activated, modifies the transmission shift schedule in an effort to increase performance under load and provide effective engine braking. It is manual shift compatible, allowing a driver to select manual shift mode and control upshifts/downshifts via shift lever mounted buttons.

Tow Mode Feature - The Aisin A466ND TCM features an integrated "Tow Mode" designed to improve braking and performance while towing. When tow mode is activated, an alternative transmission shift schedule is initiated that will:

• Delay upshifts, hold gears longer in order to keep engine rpm within ideal range for maximum performance under load.

• Provide more aggressive downshifts, initiate downshifts with greater sensitivity to driver input (accelerator pedal position).

• Hold gears longer during deceleration, initiate downshifts more aggressively in response to brake pedal input. Provides greater decent control and overall braking under load. Downshift schedule will depend largely on the degree to which the brake pedal is depressed.

Operating a vehicle in Tow Mode while unloaded may result in poor fuel economy and transmission shift points may seem random, misplaced, or overly aggressive.

Manual Shift Mode Feature - Manual shift mode can be initiated by pressing either the "+" or "-" buttons on the column mounted shift lever. Once activated, the transmission will not upshift beyond the driver selected gear. The transmission will, however, downshift accordingly in response to dropping engine speed, vehicle speed, and/or driver input via the accelerator pedal. The manual shift feature includes automatic downshift rev matching in order to provide smooth downshift gear engagements.

Fail-Safe Mode (limp mode) - The Aisin A466ND features a fail-safe mode in order to protect the transmission from certain conditions in which serious or further damage may occur. This includes, but is not limited to excessively low or excessively high automatic transmission fluid temperature. When fail-safe mode is initiated, the transmission will lock itself in 3rd gear and will not upshift or downshift. During this time, reverse will remain accessible. Placing the transmission range selector in drive will only select 3rd gear.

• Integrated tow mode provides more aggressive shift schedule tailored towards maximizing performance and braking under load.
• Excessively low/high transmission fluid temperature fail-safe feature.
• Manual shift mode; shift through all forward gears via shifter mounted "+" and "-" buttons.
• Perpetually learning TCM logic adjusts transmission shift pressures and timing in order to provide smooth, positive shifts and compensate for differences in shift solenoid performance from transmission to transmission.
