WARNING: This page is about a different car, the 2002 Mazda 626 and 2001 Mazda 626. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Turn off all electrical loads prior to performing test.
CAUTION: If accelerator pedal is pressed for more than 5 seconds while brake pedal is pressed, transaxle could be damaged. Perform test procedures within 5 seconds of each other.

Connect a tachometer to vehicle. Start engine. Move gearshift lever to "D" position. Firmly depress brake pedal with left foot, and gently depress accelerator pedal to floor with right foot. When engine speed no longer increases, quickly read RPM on tachometer and release accelerator pedal. Move gearshift lever to "N" position. Allow engine to idle for one minute or more to cool ATF. Perform same test for "R" position, "2" position and"L" position. Stall speed should be about 2000-2500 RPM. ATF temperature should be 140-158°F (60-70°C). If stall speed is not as specified, see STALL SPEED EVALUATION .
