You might want to take a closer look. The automatic has a dipstick. As for the changing interval - This seems to get discussed at least weekly here.

AUTOMATIC TRANSAXLE

Fluid capacity (drain and refill), L (qt.,
Imp. qt.): 2.5 (2.6, 2.2)

Fluid type:
Toyota Genuine ATF Type WS

Change automatic transmission fluid only
as necessary.

Generally, it is necessary to change
automatic transmission fluid only if your
vehicle is driven under one of the Special
Operating Conditions listed in your
“Scheduled Maintenance Guide” or
“Owner’s Manual Supplement”. When
changing the automatic transmission fluid,
use only “Toyota Genuine ATF Type WS”
(ATF JWS3324 or NWS9638) to aid in
assuring maximum transaxle performance.
Notice: Using automatic transmission
fluid other than “Toyota Genuine ATF
Type WS” may cause deterioration in
shift quality, locking up of your transmission
accompanied by vibration, and
ultimately damage the automatic transmission
of your vehicle.
Please contact your Toyota dealer for further
details.
