    3. Check the amount of automatic transmission fluid that comes out of the overflow hole.
      • If the amount of automatic transmission fluid that comes out of the overflow hole is large, proceed to step [*1].
      • If no automatic transmission fluid comes out of the overflow hole, proceed to step [*2].
      NOTE:

      If only a small amount of automatic transmission fluid (approximately 5 cc) comes out of the overflow hole, then only automatic transmission fluid remaining in the No. 1 transmission oil filler tube has come out. This is not considered to be overflow.

    4. If the amount of automatic transmission fluid that comes out of the overflow hole is large, wait until the automatic transmission fluid flow slows and only drips come out. [*1]

      HINT: 

      The automatic transmission fluid flow will not stop completely because the automatic transmission fluid continues to expand as its temperature increases.
