1. Before driving, the A/T fluid level can be checked at A/T fluid temperatures of 30° to 50°C (86° to 122°F) using the "COLD" range on the A/T fluid level gauge as follows: Park the vehicle on a level surface and set the parking brake. Start the engine and move the selector lever through each gear position. Shift the selector lever into the "P" position. Check the A/T fluid level with the engine idling. Remove the A/T fluid level gauge and wipe it clean with a lint-free paper. CAUTION: When wiping the A/T fluid from the A/T fluid level gauge, always use a lint-free paper, not a cloth. Re-insert the A/T fluid level gauge into the A/T fluid charging pipe until the cap contacts the top of the A/T fluid charging pipe as shown. CAUTION: To check A/T fluid level, insert the A/T fluid level gauge until the cap contacts the top of the A/T fluid charging pipe, with the gauge reversed from the normal inserted position. Remove the A/T fluid level gauge and note the A/T fluid level. If the A/T fluid level is at low side of range, add A/T fluid to the transmission through the A/T fluid charging pipe. CAUTION: Do not overfill the transmission with A/T fluid. Install the A/T fluid level gauge and the A/T fluid level gauge bolt. A/T fluid level gauge bolt: Refer to " «2WD: EXPLODED VIEW»(ref-519782-S12129575412012122900000) " (2WD) or " «4WD: EXPLODED VIEW»(ref-519782-S15494186702012122900000) " (4WD) .
2. Warm up the engine and transmission.
3. Check for any A/T fluid leaks.
4. Drive the vehicle to increase the A/T fluid temperature to 80°C (176°F).
5. Allow the A/T fluid temperature to fall to approximately 65°C (149°F). Use the CONSULT to monitor the A/T fluid temperature as follows: NOTE: The A/T fluid level will be significantly affected by the A/T fluid temperature as shown in illustration above. Therefore monitor the A/T fluid temperature data using the CONSULT. Connect CONSULT to data link connector. Select "MAIN SIGNALS" in "DATA MONITOR" mode for "A/T" with CONSULT. Read out the value of "ATF TEMP 1".
6. Re-check the A/T fluid level at A/T fluid temperatures of approximately 65°C (149°F) using the "HOT" range on the A/T fluid level gauge as shown. The HOT range is between 50° - 80°C (122° - 176°F). CAUTION: When wiping the A/T fluid from the A/T fluid level gauge, always use lint-free paper, not a cloth. To check the A/T fluid level, insert the A/T fluid level gauge until the cap contacts the top of the A/T fluid charging pipe, with the gauge reversed from the normal inserted position as shown.
7. Check the A/T fluid condition. If the A/T fluid is very dark or has some burned smell, there may be an internal problem with the transmission. Refer to «WIRING DIAGRAM»(ref-519782-S13494545242012122900000) . Flush the transmission cooling system after repairing the transmission.
