What transmission does the Lexus IS 350 have?

The Lexus IS 350 uses an 8-speed automatic transmission in its current form; older models ran a 6-speed automatic. There are no factory manual IS 350 variants today.

Overview: Transmission choice has evolved across the IS line. The model year and market determine the gearbox; this article outlines when the switch occurred and what you should expect in modern IS 350s, plus notes on drivetrain options and availability.

Transmission history by model year

Before listing the evolution by era, note that Lexus shifted from 6-speed to 8-speed automatic starting with later IS generations. The IS 350 has traditionally been offered with automatic transmissions only.

Earlier IS 350 models (approximately 2006–2013) used a 6-speed automatic transmission.

Newer IS 350 models (approximately 2014–present) use an 8-speed automatic transmission.

In summary, the transmission moved from 6-speed to 8-speed, aligning with Lexus’ broader push for more efficient automatics in the IS lineup.

Current configuration and variations

Before listing the current practical configurations, note that the IS 350 is offered with rear-wheel drive (RWD) or all-wheel drive (AWD), but both configurations use the 8-speed automatic; there is no manual option.

The 8-speed automatic is paired to the 3.5-liter V6 engine, with paddle shifters and a manual shift mode on most trims.

All-wheel-drive availability exists on select trims, but both RWD and AWD versions use the same 8-speed automatic gearbox; the drivetrain hardware, not the gearbox, defines the difference.

Conclusion: Regardless of drivetrain, today’s IS 350 uses the same 8-speed automatic transmission across modern models, delivering smooth shifts and refined performance.

Summary: The Lexus IS 350’s transmission has evolved from a 6-speed automatic in earlier years to a modern 8-speed automatic in current models. Both rear-wheel and all-wheel drive options share the same 8-speed gearbox, and there is no factory manual transmission offered for the IS 350.

Is the IS 350 6 speed or 8 speed?

The rear wheel drive gets an 8 speed automatic but a IS350 AWD gets a 6 speed automatic. IS350 can hit 60 in 5.6/5.7 seconds.

What transmission does the Lexus IS350 have?

The luxury 2023 Lexus IS 350 always steps up to the occasion with a trendsetting sport performance, thanks to its dynamic powertrains all mated to an eight-speed sport direct-shift automatic transmission.

Does Lexus have CVT transmission?

Yes, Lexus uses Continuously Variable Transmissions (CVT) in some of its vehicles, particularly in its hybrid models. Lexus calls its specific version an "e-CVT," which is an electronically controlled continuously variable transmission that combines a CVT with a planetary gearset to simulate traditional gear changes.
Lexus hybrid transmissions

LC 500h: This model uses a unique transmission that blends a CVT with a four-speed automatic to create nine "virtual" gear ratios.
RX Hybrid: Some RX hybrid models, like the RX 350 Hybrid, come standard with an e-CVT that is paired with the hybrid powertrain.
UX200: The 2019 UX200 was the first production vehicle to be equipped with a CVT that is paired with a "gear" setup.

Other Lexus vehicles

Non-hybrid models: Lexus generally does not use CVTs in its non-hybrid models, preferring other types of transmissions.

What are the common problems with the IS 350?

Common problems with the Lexus IS350 include fuel pump failures, steering system issues, and problems with emissions control systems. Other issues can include dashboard melting, discolored interior rearview mirrors, check engine lights, and potential problems with hard starting or the navigation system.
Recalls and major issues

Fuel pump failures: A specific recall addressed a failure in the low-pressure fuel pump that could cause the engine to stall while driving.
Steering failures: Some models have experienced power steering failure.
Takata airbag recalls: Like many other vehicles, some IS350s were subject to recalls for faulty Takata airbags.

Common complaints and minor issues

Dashboard melting: Some owners report that the dashboard surface can become discolored or "melt".
Discolored rearview mirror: The inside rearview mirror may develop discoloration.
Check engine light: Various issues, such as problems with the emissions control system or catalytic converter, can trigger the check engine light.
Hard starting: Some models may experience hard starting issues that can sometimes be corrected with updated PCM software.
Fuel economy: Some owners find the fuel economy to be lower than expected.
Road noise: Certain model years have been noted for having excessive road noise.
