Your 2012 Hyundai Sonata Hybrid benefits from a methodical, documented process. We begin with a fluid level and condition inspection and a scan-tool check for transmission fault codes. Next, well recommend either a drain-and-fill or a full exchange based on fluid condition and service history. Where the design allows, we service the pan and filter and install a new pan gasket. The transmission is then filled with the manufacturer-specified fluid and brought to the factory fluid-temperature specification before final level set. A verification road test confirms shift quality and adaptation behavior under real-world loads. If coverage applies, we provide the certified documentation typically required for warranty claims.
