1. Inspect the amount of engine oil. Replenish the engine oil if necessary. Refer to LU, "Inspection".
2. Drive for about 10 minutes to warm up the vehicle so that the A/T fluid temperature is to 50 to 80C (122 to 176F).
3. Inspect the amount of ATF. Replenish if necessary. Refer to TM, "Inspection".
4. Remove fluid pressure detection plug.
5. Install the joint pipe adapter [SST: KV31103600 ( - )], adapter [SST: 25054000 (J-25695-4)], and oil pressure gauge set (commercial service tool).
