I own a 2014 Nissan Sentra with a CVT transmission. In February 2023, at 152,511 miles, the dealer replaced engine seals and gaskets, and topped off the transmission fluid. The Nissan service advisor warned me not to intervene further, except to add fluid and replace seals, since the CVT had never been serviced.

However, in April 2024 at 169,216 miles, I took the car to an AAMCO franchise to check the fluid level. The owner informed me the CV axle seal was leaking and needed replacement. I reluctantly agreed. He later told me the CVT had no fluid and pushed their silver service package. I expressed my concerns about the dealer’s warning and insisted on only adding fluid. Despite this, they proceeded with extensive work.

Only 3,600 miles later, in July 2025, the CVT began failing badly. A local shop confirmed leaking seals, and the dealer verified axle seal leaks and CVT failure. I suspect AAMCO used scare tactics and may have worsened the problem, possibly leading to premature failure. 😞🔧

I’d greatly appreciate your professional thoughts on this matter. Thank you! 🙏
