    Transmission Fluid Type

    Transmission Fluid Type Operation:

    Automatic Transmission Fluid (ATF) can be petroleum-based, partially synthetic, or totally synthetic-based oil. All domestic automobile manufacturers require a petroleum-based fluid in their automatic transmissions; however, some imported vehicles require the use of a partially synthetic fluid.ATF is a liquid compound that also includes special additives that allow the lubricant to better meet the flow and friction requirements of an automatic transmission.ATF is normally dyed red, primarily to distinguish it from engine oil when determining the source of fluid leaks.

    How To Instructions:

    Inspect - Check for obvious problems.
    Replace - Out with the old, in with the new.
