Service function guideCVT Fluid and Adaptation Service

This workshop guide covers the complete CVT (continuously variable transmission) fluid and adaptation service, from understanding the push-belt and pulley system through to the final road test and relearn confirmation. It is written for working mechanics and experienced DIY owners who already have diagnostic scan tool familiarity and want a repeatable, professional procedure. You will learn how to prepare the vehicle and equipment, drain and refill the fluid correctly, reset and relearn the transmission control module adaptations, and verify the result with live data and a structured test drive. The guide also explains how the job differs across common CVT families, the mistakes that cause premature failure, and how to troubleshoot a relearn that will not complete.
