What transmission is in Lexus is350?
The IS350’s transmission is an automatic unit in every modern iteration, with the current generations using an eight-speed automatic. Earlier models used a six-speed automatic. This article explains how the transmission has evolved and what you’ll typically find today.
Overview by Generation
The transmission setup of the IS350 has evolved as the model itself was refreshed. The following list summarizes the standard transmissions by main generation and highlights key notes about drive options.
- 2006–2013 (First generation, IS350 and IS250): 6-speed automatic transmission with manual shift mode; rear-wheel drive is standard, with all-wheel drive optional on certain variants.
- 2014–2020 (Second generation, IS350): 8-speed automatic transmission across IS350 models; improved response, paddle shifters, and Sport mode; all-wheel drive available on select trims.
- 2021–present (Current generation and mid-cycle refresh): 8-speed automatic transmission remains standard; refinement in shift logic and adaptive mapping; no manual transmission option is offered.
Across these generations, the IS350 transitioned from a six-speed auto to an eight-speed auto, with no manual transmission offered in the U.S. market in the newer models.
Technical notes and features
Beyond the basic count of gears, several characteristics define how the IS350’s automatic behaves and how it supports performance and everyday driving.
Drive modes and shift behavior
- 8-speed automatic with adaptive shift logic that changes response based on driving style and conditions.
- Paddle shifters provided for manual control when desired.
- Drive mode selections (including Eco, Normal, Sport, and Sport+ in many trims) that adjust throttle, transmission mapping, and shift timing.
The combination of eight gears, paddle shifting, and selectable drive modes aims to balance smooth everyday driving with responsive performance when pushed.
All-wheel drive and performance notes
- Rear-wheel drive is standard on most IS350 variants, with all-wheel drive available on some configurations, depending on model year and market.
- The eight-speed unit is a torque-converter automatic (not a dual-clutch), chosen for smooth shifts and broad reliability in daily use.
These features influence acceleration feel, fuel efficiency, and handling characteristics, making the IS350 versatile for both city driving and highway cruising.
Summary
In summary, the Lexus IS350 has consistently used an automatic transmission, moving from a six-speed unit in earlier generations to an eight-speed automatic in the modern era. The current IS350 emphasizes smooth shifts, paddle-control options, and multiple drive modes, with AWD available on certain trims and no traditional manual option in recent years. For buyers or owners, confirming the exact transmission and drivetrain options by model year is advisable, as configurations can vary by market and production run.
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.
Does Lexus use a CVT transmission?
They put a CVT or a continuously variable transmission on one of their vehicles the Lexus UX.
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.
