What kind of transmission does a Toyota 4Runner have?

The Toyota 4Runner currently uses a five‑speed automatic transmission. There is no manual transmission option in the latest models, and it pairs with a 4.0-liter V6 engine in both 2WD and 4WD configurations.

Since the fifth‑generation redesign began in 2010, Toyota has outfitted the 4Runner with a 5‑speed automatic transmission (electronically controlled) mated to the 4.0L V6. The system is designed for rugged off‑road use and is paired with a two‑speed transfer case for the four‑wheel‑drive variants. Buyers typically choose between rear‑wheel drive and part‑time four‑wheel drive, depending on trim and intended use.

Current Transmission Configuration

The following points summarize the transmission setup that you’ll find on modern 4Runners.

• Transmission type: 5‑speed automatic transmission (electronically controlled).


• Engine pairing: 4.0‑liter V6 engine (1GR‑FE) paired with the 5‑speed auto.


• Drivetrain options: available in 2WD and 4WD (part‑time) with a two‑speed transfer case.


• Manual transmission option: not offered in the current generation.

Conclusion: The 4Runner’s drivetrain emphasizes reliability and off‑road capability with an automatic transmission, rather than a manual gear option in today’s models.

Historical context and variations

In earlier generations and certain markets, there were different transmission options available. For the U.S. market today, Toyota has maintained the 5‑speed automatic across trim levels—from SR5 to Trail and TRD Pro—without a factory manual option in the current generation.

Summary

In brief, a modern Toyota 4Runner uses a 5‑speed automatic transmission paired with a 4.0L V6, available in 2WD or part‑time 4WD. There is no manual transmission option in the current lineup, reflecting Toyota’s focus on durability and off‑road capability with an automatic system. This configuration remains consistent across recent model years, making maintenance and operation straightforward for most buyers.

Do 4Runners have CVT?

No, the Toyota 4Runner does not have a CVT transmission; it uses a traditional automatic transmission. The 4Runner has used various automatic transmissions throughout its history, including a 5-speed automatic for recent models and a newer 8-speed automatic in the sixth generation. 

• Current and recent models: Use a 5-speed automatic transmission. For example, the 2023 model has a 4.0L V6 engine paired with a five-speed automatic. 
• Sixth-generation (2025) models: Feature an 8-speed automatic transmission. 
• Hybrid models: Note that even the upcoming 4Runner hybrid, called "i-Force Max," uses a conventional automatic transmission and does not use a CVT, as seen in models like the Prius and RAV4 Hybrid. 

What year 4Runner to stay away from?

Years to stay away from include the 2001-2002 models due to frame rust and poor crash test scores, the 2003-2005 models for head gasket issues, significant body/frame rust, and dashboard cracking, and the 2015 model for potential airbag inconsistencies and electronic problems. 
Third Generation (1996-2002)

• 2001-2002: Prone to significant body and frame rust. They also have lower crash test scores than other years. 
• Note: These models had the manual transmission and locking rear differential eliminated, which could be less desirable for off-roading enthusiasts. 

Fourth Generation (2003-2009)

• 2003-2005: These models are considered the worst for the fourth generation due to multiple serious issues, including: 
  • Head gasket failures (especially with the V6 engine). 
  • Significant body and frame rust. 
  • Cracking dashboards. 
  • Poor safety ratings due to subpar headrests and seats. 
• 2015: This model year is notable for issues with the infotainment system, steering, and warped brake rotors. 

Fifth Generation (2010-Present)

• 2015: Had some electronic issues, like infotainment glitches, Bluetooth problems, and a tendency for brake rotors to warp. 
• 2010: Reports of electrical faults, including dashboard light and sensor malfunctions. 

What transmission does the 4Runner use?

All 4Runners come with a 278-hp turbocharged 2.4-liter four-cylinder and an eight-speed automatic transmission. A rear-wheel-drive layout is standard, but a full-time four-wheel drive system is optional and comes with a two-speed transfer case with high and low range.

Do 4Runners have transmission problems?

Yes, older and newer 4Runners have reported transmission problems, including shifting issues, slipping, and torque converter failures, often associated with high mileage or, in the case of the new 2025 model, its new turbocharged powertrain. Common signs include delayed shifting, grinding noises, and a burning smell. Problems can be linked to high mileage, incorrect fluid maintenance, or issues with specific components like the neutral safety switch.
 
Common issues by generation

• High mileage models:
  • Shifting problems and slipping, particularly in models from 1990-2011 and 2016. 
  • Issues often appear between 125,000 and 150,000 miles. 
  • Neutral safety switch issues are also common. 
• 2025 model:
  • Early reports indicate potential problems with the new turbocharged engine and transmission. 
  • Some owners have reported transmission slipping, clunking, and a high-stall torque converter feel. 
  • This is often attributed to the new, more complex powertrain design. 

Warning signs to watch for

• Delayed or hesitant shifting: The transmission takes longer than usual to change gears. 
• Strange noises: Grinding, whining, or clunking sounds when shifting. 
• Burning smell: This can indicate overheating transmission fluid. 
• Slipping: The engine revs up, but the vehicle doesn't accelerate as expected, feeling like a gear is missed. 
• Transmission warning light: This light illuminates when the system detects a problem. 
• Leaks: Transmission fluid leaks can indicate a need for a fluid change or a more serious issue. 

What you can do

• Perform regular maintenance: Change the transmission fluid every 60,000 miles or six years, even if the manufacturer claims it's a "lifetime" fluid, especially on older models. 
• Address issues early: If you notice any of the warning signs, have the vehicle inspected by a qualified mechanic to prevent more severe damage.
