Hard or delayed shifts

Burnt smell from transmission fluid

Reached manufacturer service interval (usually 60,000 to 100,000 miles)

What It Is

Transmission fluid lubricates, cools, and provides hydraulic pressure for shifting. It breaks down over time and miles.

Why It Matters

Old fluid causes wear inside the transmission. A $200 service is much cheaper than a $4,000 rebuild.

Frequently Asked Questions

Drain and fill or full flush?

Drain and fill replaces about 40 percent of the fluid. Flush replaces nearly all. Many shops now avoid flushes on transmissions over 100,000 miles.

Does my CVT need fluid changes?

Yes. CVTs are very picky about fluid type and intervals. Follow the manufacturer's schedule exactly.
