8. Start the engine, and run it at 2,000 rpm in the N or
P position.
9. Measure line pressure at the line pressure
inspection hole (A) in the N or P position.
NOTE: Higher pressure may be indicated if
measurements are made in shift lever position
other than N or P.
Pressure Fluid Pressure
Standard
Line (A) 850 910 kPa
(8.7 9.3 kgf/cm ,
120 130 psi)
10. Shift to the 1 position, and measure 1st clutch
pressure at the 1st clutch pressure inspection hole
(B).
11. Shift to the 2 position, and measure 2nd clutch
pressure at the 2nd clutch pressure inspection hole
(B).
12. Shift to the P position, then press the brake pedal
and hold it.
13. Shift to the D4 position, and release the brake pedal
(the transmission should be in 1st gear).
14. Accelerate the engine to 2,500 rpm (the
transmission will shift to 2nd gear).
15. Release the accelerator for more than 5 seconds
after the transmission is shifted to 2nd gear (the
engine will come down to about 1,000 rpm).
16. Press the accelerator very slowly to increase
engine speed to 2,000 rpm gradually over 5
seconds, then hold it at 2,000 rpm.
17. Measure 3rd and 4th clutch pressure at 3rd clutch
pressure inspection hole (D), and 4th clutch
pressure inspection hole (E) (the transmission will
shift from 2nd gear to 3rd gear, and then 4th gear).
18. Bring the engine back to an idle, then apply the
brake to stop the wheels from rotating.
