NOTE: The transmission oil temperature must be above 27° C (80° F).
  1. With the vehicle engine running, select reverse gear for over 2 seconds.
  2. Shift the transmission to Drive and accelerate the vehicle from a stop at a steady 15 degree throttle opening and perform a 2-3 shift while noting the 1st 2-3 OD CVI.
  3. Repeat step  1, and step  2 until the 1st 2-3 upshift becomes smooth and the 1st 2-3 OD CVI stabilizes.
