Line Pressure Test
Line Pressure Test1. Perform mechanical system test preparation. (See Mechanical System Test Preparation.)
Warning:
^ Removing the square head plug when the ATF is hot can be dangerous. Hot ATF can come out of the opening and badly burn you. Before removing the square head plug, allow the ATF to cool.
2. Connect the SSTs (49 HD64 406A, 49 0378 400C) to the line pressure inspection port and replace the gauge of the SST (49 0378 400C) with the SST (49 13019 90113).
3. Start the engine and warm it up until the ATF reaches 60-70°C (140-158°F).
4. Shift the selector lever to the D range.
5. Read the line pressure while the engine is idling for the D range.
6. Read the line pressure while the engine is idling for the R position and M range in the same manner as in Steps 4-5.
Note:
^ Replace the SST in step with the line pressure of each ranges and positions.
- 49 B019 901B: 0-1,000 kPa (0-10.2 kgf/cm 2, 0-145 psi)
- 49 0378 40OC: 0-2,500 kPa (0-25.5 kgf/cm2, 0-363 psi)
7. Stop the engine, then replace the SST (49 B01 9 901 B) with the gauge of the SST (49 0378 400C).
8. Start the engine.
9. Firmly depress the brake pedal with the left foot.
10. Shift the selector lever to the D range.
Caution:
^ If the accelerator pedal is pressed for more than 5 s while the brake pedal is pressed, the transmission could be damaged. Therefore, perform Steps 11 and 12 within 5 s.
11. Gradually depress the accelerator pedal with the right foot.
12. When the engine speed no longer increases, quickly read the line pressure and release the accelerator pedal.
13. Shift the selector lever to the N position and idle the engine for 1 min or more to cool the ATF.
14. Read the line pressure at the engine stall speed for the M range and R position in the same manner as in Steps 9-13.

Warning:
^ Removing the square head plug when the ATF is hot can be dangerous. Hot ATF can come out of the opening and badly burn you. Before removing the square head plug, allow the ATF to cool.
15. Remove the SSTs.
16. Install the test plug and O-ring in the inspection port.
