Honda drivers are always recommended towards the use of Honda brand transmission fluid. The fluid is made specifically for Honda vehicles and allows optimal function of the drivetrain.
If you want your Honda transmission to shift properly do not use anything but genuine Honda automatic transmission fluid. Use only Honda ATF DW-1 fluid. Use any substitute at your own risk.
I highly recommend you get your fluid from a Honda dealer. SLF or VTF.

For a 2004 Honda Civic, the recommended transmission fluid is Honda ATF-Z1 (Automatic Transmission Fluid). It is crucial to use the specified fluid to ensure proper operation and longevity of the transmission. If ATF-Z1 is not available, you can use a compatible alternative, such as an ATF that meets the Honda specification. Always check your owner's manual for the most accurate and specific information.
