The Nissan Titan is a full-size pickup truck designed to compete with other heavy-duty and light-duty trucks in its class. Since its introduction in the early 2000s, the Titan has been known for its powerful V8 engines, towing capability, and comfortable ride. One of the most common questions owners and shoppers ask is: what transmission is in a Nissan Titan? The answer depends on the model year, engine choice, and whether you are looking at a standard Titan or the heavier-duty Titan XD.
This article breaks down the different transmissions used in the Nissan Titan over the years and explains how they perform, what makes them unique, and what owners should know about maintenance and reliability.
What Transmission Is in a Nissan Titan?
First-Generation Nissan Titan (2004–2015)
The first-generation Nissan Titan was launched for the 2004 model year and was powered primarily by a 5.6-liter Endurance V8 engine. During this generation, Nissan offered both automatic and manual transmission options.
5-Speed Automatic Transmission (RE5R05A)
Most Nissan Titans from 2004 to 2015 came equipped with a 5-speed automatic transmission, commonly known by its internal code RE5R05A. This transmission was built by Jatco, a Nissan-affiliated transmission manufacturer.
Key features of the RE5R05A include:
- Five forward gears
- Electronic control with adaptive shift logic
- Designed to handle V8 torque and towing demands
- Used in several Nissan and Infiniti vehicles of the same era
This transmission is known for smooth shifting and decent durability when properly maintained. Regular fluid changes are critical, especially for owners who tow heavy loads or drive in hot climates.
6-Speed Manual Transmission (FS6R31A)
From 2004 to around 2010, Nissan also offered a 6-speed manual transmission in some Titan models. This transmission is known as the FS6R31A.
While less common, the manual Titan appealed to drivers who wanted more control and a traditional truck-driving experience. However, due to declining demand for manual transmissions in full-size trucks, Nissan eventually discontinued this option.
Second-Generation Nissan Titan (2016–Present)
The second-generation Nissan Titan debuted for the 2016 model year with updated styling, improved technology, and new transmission options.
7-Speed Automatic Transmission (RE7R01A / JR710E)
Most gasoline-powered Nissan Titans from 2016 onward use a 7-speed automatic transmission. This transmission is often referred to as the RE7R01A or JR710E, depending on the naming convention.
Highlights of the 7-speed automatic include:
- Improved fuel efficiency compared to the older 5-speed
- Smoother acceleration and better highway performance
- Enhanced towing and hauling capability
- Better gear spacing for both city and highway driving
This transmission pairs with the 5.6-liter Endurance V8 and has become the standard gearbox for modern Nissan Titans.
Nissan Titan XD Transmissions
The Nissan Titan XD is a heavier-duty version of the Titan designed to sit between traditional half-ton and three-quarter-ton trucks. Its transmission options differ slightly from the standard Titan.

6-Speed Automatic (Diesel Models)
The Titan XD equipped with the 5.0-liter Cummins turbodiesel V8 (available from 2016 to 2019) used a heavy-duty 6-speed automatic transmission supplied by Aisin.
This transmission was engineered specifically to handle:
- High diesel torque output
- Heavy towing demands
- Commercial-grade use
Although the diesel Titan XD was discontinued, its transmission is widely regarded as strong and reliable when maintained correctly.
7-Speed Automatic (Gasoline Titan XD)
Gasoline-powered Titan XD models use the same 7-speed automatic transmission found in the standard Titan, paired with the 5.6-liter V8 engine.
Transmission Reliability and Maintenance
Overall, Nissan Titan transmissions are considered reliable, but like any truck, longevity depends on care and usage.
Maintenance tips include:
- Change transmission fluid at recommended intervals
- Use the correct Nissan-approved transmission fluid
- Install an auxiliary transmission cooler if you tow frequently
- Address shifting issues early to prevent major damage
Ignoring transmission maintenance can lead to overheating, slipping gears, or premature failure—especially in trucks used for towing or off-road driving.
Final Thoughts
So, what transmission is in a Nissan Titan? The answer varies by year and configuration. Earlier models used a 5-speed automatic or 6-speed manual, while modern Titans rely on a more efficient 7-speed automatic. The Titan XD adds a heavy-duty 6-speed automatic for diesel models.
Understanding which transmission your Nissan Titan has can help you maintain it properly, choose the right truck for your needs, and make informed repair or upgrade decisions. Whether you’re towing, hauling, or daily driving, the Titan’s transmission plays a crucial role in delivering power and performance reliably.
