Synthetic ATF is available on aftermarket brands, offering better performance and service life for certain applications (such as frequent trailer towing).

The use of a lint free white rag to wipe the dipstick on automatic transmissions is advised so that the color of the fluid can be checked. Dark brown or black ATF can be an indicator of a transmission problem, vehicle abuse, or fluid that has far exceeded its useful life. Overused ATF often has reduced lubrication properties and abrasive friction materials (from clutches and brake bands) suspended in it; failure to replace such fluid will accelerate transmission wear and could eventually ruin an otherwise healthy transmission. However color alone is not a completely reliable indication of the service life of an ATF as most ATF products will darken with use. The manufacturer's recommended service interval is a more reliable measure of ATF life. In the absence of service or repair records, fluid color is a common means of gauging ATF service life.

Continuously variable and dual-clutch transmissions use specialized fluid.

Famous quotes containing the word current:

    I perceived that to express those impressions, to write that essential book, which is the only true one, a great writer does not, in the current meaning of the word, invent it, but, since it exists already in each one of us, interprets it. The duty and the task of a writer are those of an interpreter.
    Marcel Proust (1871–1922)
