Line Pressure Check

Note: 

•	In this test, be sure to wait for at least one minute after moving the select lever back to N range before starting the next measurement.

•	Be sure to take the measurement when the engine is fully warmed up.

1. After checking the automatic transmission (AT) level, block the front and rear wheels securely and depress the floor brake.
2. Start the engine and move the select lever from N to D. Using a stop watch, measure the time it takes from this point until shift shock is felt.
3. Similarly, measure the time lag from N to R range.

Special Tools

For equivalent regional tools, refer to Special Tools .

1. Check the ATF level and condition. Refer to Transmission Fluid Level and Condition Check .
2. Turn the engine OFF.
3. Remove the line pressure test hole plug (1).
4. Install the DT-46450-01 oil pressure gauge and DT-50046 oil pressure gauge adapter to the oil pressure inspection hole in the transmission case.

Warning: Keep the brakes applied at all times in order to prevent unexpected vehicle motion. Personal injury may result if the vehicle moves unexpectedly.

5. Chock the front and rear wheels and apply the parking brake fully.

Note: 

•	Ensure that the ATF does not leak after installing the oil pressure gauge.

•	Do not hold the stall condition for longer than 5 seconds at a time. Be sure to cool the transmission, idling for at least 30 seconds before starting the next test.

6. Start the engine and depress the foot brake. Measure the oil pressure in D and R ranges when idling, and when the engine has stalled.
7. Compare the line pressure test results with the line pressure results in the following table. If the line pressure is not a specified one, refer to the line pressure test diagnosis in this procedure for further evaluation.
8. Turn the engine OFF.
9. Remove the DT-46450-01 oil pressure gauge and DT-50046 oil pressure gauge adapter.
10. Install the line pressure test hole plug (1).
