To extend the life and improve the performance of your transmission, it's important to have its Automatic Transmission Fluid (ATF) replaced completely according to your manufacturer's recommended schedule. That's because heat and mileage cause the vital additives in ATF to become oxidized, depleted, and inert. And worn-out ATF can result in rough shifting, accelerated wear and even transmission failure.
It only takes about 10–15 minutes for us to:
- Completely drain the transmission and torque converter
- Refill it with new Valvoline® ATF

If your car is shifting roughly, you may need to have your transmission fluid filled.
