Automatic transmission 345010-34040 5.0 V8 NISSAN TITAN XD 2016

part number 345010-34040 refers to the heavy-duty Aisin A466ND 6-speed automatic transmission. This specific unit was exclusively paired with the 5.0L Cummins V8 Turbo Diesel engine in the Nissan Titan XD (2016–2019).

Unlike the standard Titan which used a Nissan/Jatco 7-speed, the Titan XD Diesel required this reinforced Aisin unit to manage the engine’s 555 lb-ft of torque.

Technical Specifications: Aisin A466ND

Performance Characteristics

• Heavy-Duty Lineage: The A466ND is closely related to the Aisin AS69RC used in Ram 3500/4500/5500 chassis cab trucks, known for extreme durability in commercial towing applications.

• Geared for Towing: It features a high-capacity torque converter and aggressive lock-up strategy to keep transmission temperatures low while hauling up to 12,000+ lbs.

• Shift Logic: Uses an external Transmission Control Module (TCM) that adjusts shift points based on load and grade (Grade Logic Control).

Critical Notes for Inventory & Service

1. Fluid Sensitivity: This transmission is highly specific regarding fluid. It typically requires Nissan Matic S or an equivalent high-quality synthetic ATF that meets Aisin heavy-duty specs. Using the wrong fluid can lead to harsh shifts and premature clutch wear.

2. Part Interchange: While the transmission physically fits 2016–2019 models, verify the 345010-34040 code against the donor vehicle’s build date. There were minor software/solenoid updates in later production years (2018+).

3. Oil Pan Upgrades: This model is a popular candidate for deep-sump aluminum oil pans (like those from PML or PPE) to increase fluid capacity and cooling—an important detail if you are selling this as a “towing ready” unit.

4. Compatibility Warning: This will not fit the 5.6L Gasoline V8 Titan XD. The bellhousing pattern and internal gearing are completely different.
