The current Lexus IS300 uses an 8-speed automatic transmission. Historically, the IS300 line began with a 5-speed manual option and moved through automatic-only configurations before settling on an 8-speed automatic in today’s models. This article explains how the gearbox has evolved across generations and markets.
First generation IS300 (2001–2005)
The IS300 debuted with two gearbox options to suit different driving preferences, including a traditional manual for enthusiasts and a conventional automatic for convenience.
- 5-speed manual transmission (standard with the 3.0-liter inline-six)
- 5-speed automatic transmission with overdrive
Conclusion: This generation offered both a manual and an automatic, a rarity in Lexus showrooms at the time and a key selling point for driving purists.
Second generation IS (2006–2013)
As the model evolved, Lexus shifted toward automatic transmissions in most markets, aligning with broader industry trends and reliability considerations.
- 6-speed automatic transmission (used on the IS 250 and IS 350)
Conclusion: Manual transmissions were not offered in the North American market for this generation; the IS lineup relied on a 6-speed automatic.
Current generation and IS300 today (2014–present)
The modern IS lineup centers on efficient and performance-oriented automatics. In markets where the gasoline IS300 is sold with the turbocharged 2.0-liter engine, the transmission is an 8-speed automatic. The IS 300h hybrid variant uses a different setup.
- 8-speed Direct Shift automatic (8AT) paired with the turbocharged 2.0L engine for gasoline IS300
- eCVT (hybrid IS 300h) in many markets
Conclusion: The current IS300 gasoline model is automatic-only, featuring an 8-speed automatic in most markets. Manual transmissions are no longer offered for the IS300 gasoline variant.
Clarification on IS 300h and other variants
In Europe and some regions, the name IS 300h refers to a hybrid version that uses a CVT rather than a conventional automatic. This is different from the gasoline IS300 with the 8-speed automatic. When discussing the IS300, be sure to specify the market and exact model year to determine the correct gearbox.
Summary
Transmission history at a glance: the first IS300 offered a 5-speed manual and a 5-speed automatic; the second generation moved to a 6-speed automatic with no manual option in most markets; the current IS300 uses an 8-speed automatic, while the hybrid IS 300h employs a CVT in many markets. Market and year can affect the exact configuration, so check the specific model you’re researching.
Which is better, 8-speed or CVT?
CVT transmissions are ideal for city driving and fuel efficiency, making them great for daily commuting in vehicles like the Nissan Rogue. 8-speed automatics, on the other hand, excel in vehicles used for towing, off-roading, or high-speed performance, such as the Nissan Frontier.
What transmission came in the IS300?
The IS 300 models were initially only available with the five-speed automatic transmission in all markets. A five-speed manual – the six-speed manual from the 2-litre model was not designed for the torque put out by the larger 2JZ-GE engine – was made available in the US in 2001 for the 2002 model year.
Do all Lexus have CVT transmission?
Lexus: Every non-hybrid is not equipped with a CVT. Lincoln: The non-hybrid Corsair and non-hybrid MKX are not equipped with CVTs. Maserati: No modern Maserati is equipped with a CVT. Mazda: No modern Mazda is equipped with a CVT.
Which lasts longer, CVT or automatic?
Follow the owner's manual for maintenance instructions. Mechanics are more familiar with automatic transmissions, meaning easier and sometimes cheaper repairs. Both transmissions can last with proper care. While CVTs average 100,000 miles or less, regular automatics often have a longer life span.
