HONDA 2007 Ridgeline - Owner's Manual - Manual (Page 256)

The rear differential should be
drained and refilled with new fluid
when this service is indicated by a
maintenance message on the
information display. This service
may be needed more often under
certain driving conditions (see page
).
Always use Honda VTM-4
Differential Fluid, and have your
dealer replace the rear differential
fluid.
Insert the dipstick all the way back
in the transmission. If the level is below the lower
mark, remove the fill plug, then
add the fluid into the hole to bring
it to the level between the upper
and lower marks.
Pour the fluid slowly and carefully so
you do not spill any. Clean up any
spill immediately; it could damage
components in the engine
compartment.
Always use Honda ATF-Z1
(automatic transmission fluid). If it’s
not available, you may use a
DEXRON III automatic
transmission fluid as a temporary
replacement. However, continued
use can affect the shift quality. Have
the transmission flushed and refilled
with Honda ATF-Z1 by your dealer
as soon as it is convenient.
If you are not sure how to add fluid,
contact your dealer.
