Gear Pressure Test: Test

NOTE: 

• How to read the torque specifications .
• Check for DTCs. If any DTCs are stored, troubleshoot and clear them first.
• Do not allow dust or other foreign particles to enter the port while installing the pressure gauge adapter.
• Be sure to check the ATF level after each pressure port test. When installing or removing the pressure gauge adapter, ATF may run out of the pressure inspection ports.
• Do not test pressure for more than 10 seconds at a time.
• Do not shift the transmission while raising the engine speed.
• VSA DTC (s) may come on during the test-drive. If the VSA DTC (s) come on, clear the DTC (s) after testing is done with the HDS.

1. A/T Oil Pressure Gauge - Set

   1. When testing the hydraulic pressure at each inspection port, select a suitable adapter from the following table, and connect each adapter to the A/T oil pressure gauge.

   Inspection Port	Tool
   Line pressure	Pressure gauge adapter B
   Over drive clutch pressure	Pressure gauge adapter A Pressure gauge adapter E

2. Vehicle - Lift
3. Engine Undercover - Remove
4. ATF Level - Check 
5. HDS - Connect
6. Line Pressure - Test

   1. Assemble the pressure gauge; install the A/T pressure test hose (A), the A/T pressure adapter (C), and pressure gauge adapter B to the A/T oil pressure gauge set (D).

   2. Remove the sealing bolt (A).

   3. Install the A/T oil pressure gauge to the line pressure inspection port.

   4. Do the VSA system disabling procedure

   6. Shift the transmission to D position/mode.

   7. Measure the line pressure from the A/T oil pressure gauge while holding the engine speed at 1, 500 rpm and at 3, 000 rpm by monitoring with the HDS.

   NOTICE 

   Do not apply the brake hard when working on a running vehicle. It may cause some damage to the drive-line.

   5. Enter the maintenance mode, then start the engine

   Pressure	Fluid Pressure
   	Standard	Service Limit
   Line (1, 500 rpm)	750-850 kPa (7.65-8.67 kgf/cm 2, 108.8-123.3 psi)	700 kPa (7.14 kgf/cm 2, 101.5 psi)
   Line (3, 000 rpm)	250-310 kPa (2.55-3.16 kgf/cm 2, 36.3-45.0 psi)	-

   8. If the line pressures are out of the service limit, refer to the problem and probable cause (s) listed in the table.

   Problem	Probable cause (s)
   No or low line pressure	ATF pump Clogged ATF strainer Valve body assembly (regulator valve) Shift solenoid valve B Over drive clutch Feed pipe (at over drive clutch)

   9. Turn the engine off.

   10. Remove the A/T oil pressure gauge.

   11. Install a new sealing bolt.

7. Over Drive Clutch Pressure - Test

   1. Remove the transmission fluid pressure sensor (B) 2. Temporarily install transmission fluid pressure sensor with the sealing washer (C) to pressure gauge adapter A. 3. Assemble the pressure gauge; install the A/T pressure test hose (D), the A/T pressure adapter (E), and pressure gauge adapter A to the A/T oil pressure gauge set (F).

   4. Install pressure gauge adapter E (quick connector) to the over drive clutch pressure inspection port.

   5. Install pressure gauge adapter A to pressure gauge adapter E (quick connector).

   6. Connect the connector (B) to the transmission fluid pressure sensor (C).

   7. Do the VSA system disabling procedure

   9. Shift the transmission to D position/mode.

   10. Measure the over drive clutch pressure from the A/T oil pressure gauge while holding the engine speed at 1, 500 rpm by monitoring with the HDS.

   NOTICE 

   Do not apply the brake hard when working on a running vehicle. It may cause some damage to the drive-line.

   8. Enter the maintenance mode, then start the engine

   Pressure	Fluid Pressure
   	Standard	Service Limit
   Over drive clutch (1, 500 rpm)	756-844 kPa (7.71-8.61 kgf/cm 2, 109.7-122.4 psi)	700 kPa (7.14 kgf/cm 2, 101.5 psi)

   11. If the over drive clutch pressure is out of the service limit, refer to the problem and probable cause (s) listed in the table.

   Problem	Probable cause (s)
   No or low over drive clutch pressure	Valve body assembly (shift valve A) Shift solenoid valve A

   12. Turn the engine off.

   13. Disconnect the connector from transmission fluid pressure sensor.

   14. Remove the A/T oil pressure gauge.

   15. Remove transmission fluid pressure sensor from pressure gauge adapter A.

   16. Install the transmission fluid pressure sensor

   .

8. ATF Level - Check 
9. All Removed Parts - Install

   1. Install the parts in the reverse order of removal.

10. DTC - Check

    1. Do an all DTC check with the HDS. If necessary, clear the DTC (s) with the HDS.
