Automatic Transmission
Pressure Test (cont'd)
7. Start the engine, and run it at 2,000 rpm in the P or
N position.
8. Measure line pressure at the line pressure
inspection hole (A).
NOTE: Higher pressure may be indicated if
measurements are made in shift lever position
other than N or P.
Pressure
Line (A) 900 960 kPa
(9.2 9.8 kgf/cm ,
130 140 psi)
9. Shift to the 1 position, and measure 1st clutch
pressure at the 1st clutch pressure inspection hole
(G) and 1st-hold clutch pressure at the 1st-hold
clutch pressure inspection hole (C).
10. Shift to the 2 position, and measure 2nd clutch
pressure at the 2nd clutch pressure inspection hole
(B).
11. Shift to the P position, then press the brake pedal
and hold it.
12. Shift to the 2 position, and release the brake pedal
(the transmission should be in 2nd gear).
13. Press the accelerator very slowly to increase
engine speed to 2,000 rpm gradually over 10
seconds, then hold it at 2,000 rpm.
14. Hold in the 2 position at 2,000 rpm, shift into N for 1
second, then shift to the D3 position (the
transmission will shift to 3rd gear), and measure
3rd clutch pressure at the 3rd clutch pressure
inspection hole (D).
15. Shift to the D position, and measure 4th clutch
pressure at the 4th clutch pressure inspection hole
(E), then in about 15 seconds, the transmission will
shift to 5th gear.
16. Measure 5th clutch pressure at the 5th clutch
pressure inspection hole (F).
17. Bring the engine back to an idle, then apply the
brake to stop the wheels from rotating.
