The 2.5L pairs with a conventional 8-speed torque-converter automatic — NOT a CVT (the Tucson has no CVT). It is a proven unit; the HEV/PHEV use a 6-speed automatic instead.
Test smooth, decisive upshifts under light and firm throttle. Any harsh shift or hunting = request service history.
Est. cost: Routine fluid service
