Our Repair Process

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.

Fluid Specification

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.

Pricing - Toyota Sequoia

A343F rebuild: $1,600 - 2,100

Common Repair Conversations

What We Help You Sort Out

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.

Slipping or delayed engagement

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.

Leaks, burning smell, or overheating

Fluid condition, leak location, and driving distance matter. If the vehicle is slipping badly or overheating, towing may be the safer next step.

Rebuild, replacement, or targeted repair

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.
