Did SC400s come in manual?

The SC400 was not offered with a factory manual transmission; it was sold with a four-speed automatic throughout its production.


To understand this, it helps to look at the SC lineup from Lexus in the 1990s. The SC400, powered by the 1UZ-FE V8, shared its drivetrain approach with other grand-touring efforts of the era—favoring smooth shifting and refined highway cruising over a manual enthusiasts’ emphasis. This article examines the official options, market variations, and what it means for collectors and potential buyers today.


Factory transmission options and production details


Key points about what was offered from the factory, and what wasn’t, for the SC400's transmission lineup.



  • The SC400 was equipped with a four-speed automatic transmission (A340E) as the standard and only factory option in the United States and most other markets during its production years.

  • There was no official factory manual transmission option for the SC400 from Lexus/VOL (the brand’s standard production lineup).

  • The SC400’s automatic pairing was designed to complement the 1UZ-FE 4.0-liter V8, prioritizing smooth power delivery and luxury refinement over row-your-own-driver engagement.


In short, the official factory configuration for the SC400 did not include a manual transmission, a stance that remained consistent across its model years and markets where the car was sold.


Enthusiast modifications and aftermarket options


Some owners have explored manual conversions or swaps, but these are not factory-supported and carry varying implications for reliability, warranty, and resale value.



  • Aftermarket manual swaps have been attempted by a niche of enthusiasts who source a compatible 5- or 6-speed gearbox from other Toyota/Lexus platforms and fitment kits.

  • Such projects typically require custom fabrication for the clutch pedal assembly, shifter linkage, ECM tuning, and possible transmission tunnel alterations.

  • Conversions can affect emissions compliance, insurance, and long-term reliability; they are generally not recommended for the average buyer seeking a stock, original example.


For collectors and owners, the absence of an official manual option means that any manual-equipped SC400 would be the result of aftermarket work, not a factory specification.


Market context and practical implications


Understanding the transmission history helps buyers assess value, authenticity, and the driving experience expected from an SC400 today.


Prospective buyers seeking an original, stock experience are more likely to encounter SC400s with the factory auto, which remains a defining characteristic of the model. Enthusiasts who prioritize driver engagement may prefer the SC300 or consider other Lexus products that offered factory manuals, or they may pursue a conversion at their own risk and expense.


Summary


Bottom line: SC400s did not come with a factory manual transmission. The model was offered exclusively with a four-speed automatic across its production run, aligning with Lexus’s luxury-tocate philosophy of smooth, effortless cruising rather than manual involvement. Any manual-equipped SC400 models on the market would be the result of aftermarket conversions, not factory design. For buyers and collectors, this distinction helps set expectations about originality and value.

Did the Lexus SC come in manual?


A 5-speed manual transmission was only offered on the SC 300 from its debut until 1997. By the end of the decade, North American SC sales began dwindling due to the lack of significant design updates since the car's introduction and marketplace changes that led to loss of interest in coupes.



Which Lexus came in the manual?


Lexus models with manual transmissions include the IS 250 (2006–2012), IS 300 (2002–2005), SC 300 (1992–1997), and ES 250/300 (1990–1996). The most recent manual transmission offered was in the 2012 IS 250 sedan. Lexus is also developing an "interactive manual drive system" for its future electric vehicles, which simulates the feeling of a manual transmission without a traditional gearbox.

  • The SC300, the other model in the first generation of the SC, was the one that offered a 5-speed manual transmission. 
  • Because the SC400 was never made with a manual, people who want a manual transmission in their SC400 must perform a swap, often using a Nissan 350Z transmission.
