When did the Tundra get a 6-speed transmission?

In brief: The Toyota Tundra first gained a six-speed automatic transmission in the 2007 model year, when Toyota paired the 5.7L i-Force V8 with a six-speed automatic. This setup remained common through the second generation until the latest redesign introduced a 10-speed unit.

Historical context: Tundra transmissions before 2007

Understanding the timeline requires looking at the Tundra’s powertrain evolution. The first-generation Tundra (1999–2006) relied on older transmissions typical for the era, including a 4-speed automatic or a 5-speed manual in various trims. There was no factory 6-speed transmission option on the original trucks during this period.

Before the 2007 refresh, Toyota’s lineup for the Tundra emphasized durability and towing capability with those older gearboxes. The key change would come with the next generation and a shift in available engines.

Below is a concise timeline of when the Tundra adopted a six-speed transmission across its generations.



• 2007 model year — Introduction of a six-speed automatic (A750F) paired with the 5.7L i-Force V8; 4.0L V6 variants continued with a different auto option.


• 2007–2021 — Six-speed automatic remains standard on the 5.7L V8 configurations; subsequent V6 options largely stayed with a five-speed automatic in many trims.


• 2022–present — Toyota shifts to a 10-speed automatic in the third-generation Tundra, introducing the i-Force MAX hybrid powertrain in the mix and moving away from the six-speed box on newly offered drivetrains.

In summary, the six-speed transmission first appeared in the 2007 model year with the 5.7L V8, and it remained a fixture through the end of the second generation before the third generation adopted a 10-speed unit.

Transmission details by engine and generation

5.7L i-Force V8 (early to mid-second generation)

The 5.7L i-Force V8 introduced in the Tundra’s second generation was typically paired with a six-speed automatic, delivering robust towing performance and smoother highway cruising compared with earlier automatics.

4.0L V6 (early generations)

Throughout the first generation and early second generation, the 4.0L V6 configurations generally used a four-speed or five-speed automatic rather than a six-speed, depending on the trim and model year.

2022 onward: Third generation and i-Force MAX

The redesigned Tundra introduced a new powertrain lineup, including the i-Force MAX (a 3.5L twin-turbo V6 with hybridization) paired with a 10-speed automatic. This marked the end of the six-speed era for the Tundra’s new models.

Why this mattered: performance and efficiency shifts

The move to a six-speed automatic in 2007 was driven by a need for better towing capability, improved acceleration characteristics at varying loads, and improved efficiency. The later shift to a 10-speed automatic in the 2022 redesign represents another step in maximizing power delivery, fuel economy, and smoothness across a broader range of speeds and driving conditions.

Current status and implications for buyers

For buyers considering a used or newer Tundra, the six-speed automatic is a hallmark of the 2007–2021 era with the 5.7L V8. If evaluating a current-generation Tundra, expect a 10-speed automatic paired with the latest powertrain options, with different performance characteristics compared to the older six-speed setups.

Summary

The Tundra first adopted a six-speed automatic in 2007, paired with the 5.7L V8, and this configuration persisted through much of the second generation. With the 2022 redesign, Toyota moved to a 10-speed automatic and introduced newer powertrains, marking the end of the six-speed era for the latest trucks. Across its history, the transmission evolution reflects Toyota’s aim to balance towing capability, acceleration, and efficiency.

What year to avoid Toyota Tundra?

Years to avoid the Toyota Tundra include the 2007, 2012, and 2022-2024 models due to significant engine problems, expensive repairs, and various other issues. The 2007 model year was the first of the second generation and had widespread secondary air injection pump failures. The 2012 is called the "worst model year" because of costly engine and transmission problems that appeared at lower mileage. The third generation, starting with the 2022 model year, has been plagued with numerous, albeit sometimes minor, problems such as infotainment issues, leaks, and other electrical and mechanical faults. 
2007 Toyota Tundra

• Primary issues: Secondary air injection pump failure, which could cause the engine to enter limp mode, and frame rust.
• Consequences: Inexpensive but critical repairs that could severely limit the truck's use, especially for towing. 

2012 Toyota Tundra

• Primary issues: Costly engine and transmission problems, including faulty air induction pumps and premature transmission failures.
• Consequences: These expensive repairs occurred at relatively low mileage, making it the "worst model year" according to CarComplaints.com. 

2022–2024 Toyota Tundra 

• Primary issues: A long list of problems including infotainment issues, engine troubles, and various leaks and noises, such as rattling dashboards, leaking sunroofs, and wind noise from window gaps. 
• Consequences: Frequent trips to the dealership and a high number of recalls have been issued for these models. 

Other model years to be cautious of

• 2005–2006: These models also had secondary air injection pump failures, though less severe than the 2007 models. 
• 2013: This year is noted for gearbox issues and lower fuel efficiency. 
• 2014: This model year experienced transmission slippage and lower fuel efficiency. 

Did the Toyota Tundra ever come with a manual transmission?

No, the current Toyota Tundra does not come with a manual transmission. Manual options were only available on first-generation Tundras (2000-2006) with the V6 engine, never with the V8. 

• First-generation Tundras (2000–2004): Offered a five-speed manual transmission with the 3.4-liter V6 engine. 
• First-generation Tundras (2005–2006): Offered a six-speed manual transmission with the 4.0-liter V6 engine. 
• Later generations: Manual transmissions were not offered on any V8 models, and no manual options have been available since the end of the first generation. 

What year of the Toyota Tundra is the most reliable?

The most reliable Toyota Tundra years are generally considered to be from the 2014-2021 model years, as these models feature proven V8 engines and refined interiors. The entire 2007-2021 second generation is highly regarded for its reliability, especially with the V8 engine, making it a solid choice for those seeking a bulletproof full-size truck. For those who can find it, the 2013 year stands out with perfect reliability ratings from sources like Consumer Reports.

Highly reliable model years 

• 2014-2021: This range is frequently cited for its proven V8 engines, more modern interiors, and strong reliability ratings. The later years, particularly 2019-2021, are noted for prioritizing safety and comfort, with some models featuring active safety features. 
• 2013: This specific model year is often highlighted as having a perfect reliability rating and high customer satisfaction scores. 
• Earlier V8 models: Years like 2010 and 2011 also received accolades for their reliability and durable V8 engines, says Toyota Direct and CarBuzz. 

What makes this generation reliable?

• Proven V8 engines: This generation was predominantly equipped with reliable V8 engines, and the long production run meant any initial issues were addressed over time. 
• Abundant parts and knowledge: The second-generation Tundras (2007–2021) are widely available on the used market, and there is extensive knowledge about them from mechanics and owners. 
• Resale value: Their reputation for dependability has contributed to strong resale values. 

Potential models to avoid

• First-generation (2000-2006): While still capable, this generation had more recalls and complaints compared to the second generation. 
• 2007 Toyota Tundra: This specific model year received more owner complaints than others, particularly regarding engine issues. 
• Newer models (2022-2023): These models experienced some manufacturing defects that led to recalls, making their long-term reliability less certain compared to the previous generation. The newest models may also have potential issues due to the short time they have been on the market, according to Autotrader.
