Eight-speed automatic — test-drive itemmajor
The eight-speed automatic is still the top mechanical cluster, though the 2021's lower overall volume makes it less dominant. Owners report the familiar accelerator-linked whine (one original owner noted it starting at 67,000 miles), delayed 1st-to-2nd shifts, and occasional loss of drive. Toyota has no warranty extension, but mechanics who see these daily rate the four-cylinder Camry's UB80 as far more durable than the V6 Highlander's version, note Toyota revised the transmission after the early 2018 builds, and point to 60,000-mile fluid changes as the key preventive. Screen it directly — warm the car, accelerate, listen for the whine — and weigh mileage and fluid history, since an out-of-warranty replacement is quoted at $3,000 up to $7,000–$9,000.
