What transmission does the Lexus IS350 use?
The Lexus IS350 uses a conventional automatic transmission, not a manual. In the first-generation IS350 (roughly 2006–2013) it employed a 6-speed automatic, and from the 2014 refresh onward it moved to an 8-speed automatic across most markets. No factory manual transmission was offered for IS350 in major markets.
Transmission history by IS350 generation
Here's a concise timeline showing how the gearbox changed across the IS350's life cycle.
- 2006–2013 IS350: 6-speed automatic transmission. This period also included optional all-wheel drive on certain trims, all using automatic gearing.
- 2014–present: 8-speed automatic transmission. Beginning with the 2014 model year, Lexus adopted an 8-speed auto for IS350 across most markets, improving shift response and efficiency. The transmission is used in both rear-wheel drive and all-wheel drive configurations.
In short, the IS350 transitioned from a 6-speed automatic to an 8-speed automatic when the model line was refreshed, and that configuration remains in use for current versions in most markets.
What that means for drivers
The move to eight gears affected performance, refinement and fuel economy. Here are the key implications for drivers:
- Smoother, quicker shifts and improved acceleration feel thanks to more gear steps.
- Better highway fuel economy due to taller top gear and optimized shift points.
- Maintenance considerations are generally in line with modern automatics; expect regular transmission fluid changes per the owner's manual, with service intervals varying by model year.
Overall, the eight-speed auto has become standard for IS350 since 2014, delivering a more modern driving experience without a manual option.
Drivetrain configurations by market
Availability of rear-wheel drive and all-wheel drive versions has varied by market and year, but the 8-speed automatic is used across both layouts in most regions since 2014.
- Rear-wheel drive IS350 commonly paired with the 8-speed automatic since the 2014 refresh.
- All-wheel drive IS350 variants also use the 8-speed automatic in model years following the switch.
- Manual transmission has not been offered for IS350 in the major markets, including the United States.
In short, whether you choose RWD or AWD, the IS350’s motive power is channeled through an eight-speed automatic in recent years, with the earlier 6-speed unit reserved for pre-2014 models.
Summary
The Lexus IS350 uses a traditional automatic transmission, evolving from a 6-speed unit in the 2006–2013 era to an 8-speed unit from 2014 onward. There is no factory manual option for IS350 in major markets. This shift aligns the IS350 with modern Lexus powertrains, delivering smoother performance and better efficiency across both RWD and AWD configurations.
Does Lexus use ZF transmissions?
Now if six turned out to be eight . . . The eight-speed transmission is not new to the automotive world. Toyota has had one in its Lexus LS and IS F sedans for a few years.
What transmission is in Lexus IS 350?
The Lexus IS350 uses an 8-speed automatic transmission for Rear-Wheel Drive (RWD) models and a 6-speed automatic transmission for All-Wheel Drive (AWD) models.

- RWD: The rear-wheel drive version of the IS350 comes with an 8-speed automatic transmission, also called the "Direct Shift" automatic.
- AWD: The all-wheel drive version of the IS350 comes with a 6-speed automatic transmission.
Does the IS350 have a CVT?
They don't have CVTs, unless it a hybrid. 6 speed CVT is an oxymoron. You have two options depending on the drive. AWD gets you the 6 speed, RWD gets you the 8 speed.
Which is better, CVT or 8 speed transmission?
A continuously variable transmission (CVT) is generally better for fuel efficiency and smooth, seamless acceleration, while an 8-speed automatic is better for performance, towing, and a more traditional driving feel with distinct gear shifts. CVTs achieve this by using a belt and pulley system to continuously adjust the gear ratio, while 8-speeds have a fixed number of gears that the transmission shifts between.

| Feature | CVT | 8-Speed Automatic |
|---|---|---|
| How it works | Uses a belt and two pulleys to provide a continuously variable range of gear ratios. | Uses a fixed number of gears that the transmission shifts between. |
| Driving feel | Very smooth, uninterrupted acceleration. Some drivers dislike the "rubber band" feeling where engine RPMs don't always correspond directly with speed. | Provides a more traditional feel with distinct gear shifts, which some drivers prefer, especially in performance applications. |
| Fuel efficiency | Generally better fuel economy because it can keep the engine in its most efficient RPM range more consistently. | Typically lower fuel economy than a CVT, although modern 8-speeds are very efficient. |
| Performance/Towing | Less suited for high-torque applications like performance cars or heavy towing. | Handles high torque loads better and is preferred for performance vehicles and towing. |
| Complexity and maintenance | Simpler and less expensive to manufacture but can be more expensive to repair if a problem arises. | More complex with more moving parts. |

Which one should you choose?
- Choose a CVT if: Fuel efficiency is your top priority, you prefer smooth and quiet acceleration, and you mostly do city or highway commuting.
- Choose an 8-speed automatic if: You want a more engaging and sporty driving experience, need to tow heavy loads, or are buying a high-performance vehicle.
