2001 - 2007: 4-speed automatic (A343F) on 4.7L V8. 2008 - 2022: 6-speed automatic (AB60F) on 5.7L V8. 2023 - 2024: Hybrid e-CVT on 3.4L twin-turbo V6 hybrid (new platform). 4WD: A340F or AB60F transfer case on 4WD models.
The Sequoia is Toyota's heaviest SUV and is frequently used for maximum towing - 8,900 lbs in some configurations. This puts far greater stress on the AB60F than typical family SUV use. Fluid changes every 30,000 miles are essential for towing applications. Solenoid and valve body repairs can often be done without a full rebuild. Transfer case chain wear is common and best addressed concurrently.
AB60F uses Toyota ATF WS. A343F uses Toyota ATF Type T-IV. Transfer case uses Toyota transfer case fluid. Change every 30,000 miles for towing use.
AB60F solenoid: 1 - 2 days. AB60F rebuild: 3 - 4 days. Transfer case rebuild: 2 days.
Every vehicle needs diagnosis before anyone can promise a repair path. These are the situations we help organize before you decide what to do next.
Tell us when it happens, whether reverse still works, and if warning lights are on. A scan and fluid check come before guessing at a rebuild.
Fluid condition, leak location, and driving distance matter. If the vehicle is slipping badly or overheating, towing may be the safer next step.
A failed solenoid, valve body, converter, or internal clutch problem can lead to very different repair paths. The goal is a clear diagnosis and written estimate.
Likely AB60F solenoid wear under sustained tow load. Get a diagnostic - often repairable for $550 - 900 before a full rebuild is needed.
Every 30,000 miles if you tow regularly. Toyota's standard recommendation isn't calibrated for maximum-capacity towing.
Transfer case chain wear - very common on 4WD Sequoia over 150k. Transfer case rebuild: $1,200 - 1,800.
Too early for definitive data - the 2023 platform is new. The twin-turbo hybrid system is a departure from Sequoia's traditional 5.7L V8. Fluid maintenance is critical from day one.
3 - 4 business days.
