■ Procedure
1. Warm up transmission to operating temperature(70’C to 90’C) by normal driving
2. During the following steps a transmission sump temperature between 65’C and 95’C has
to be maintained as those are the boundaries for the adaptive functionality.
3. Move shift lever between “N” to “D” for 15 times (as braked). A pause of 2 sec in each
position must be made during the repeat
4. Move shift lever between “N” to “R” for 15 times (as braked). A pause of 2 sec in each
5. Drive at steady throttle through all gears 1-6 at pedals from 10% to 100% in 10% increments.
Each combination of pedal position and gear shift must be done at least 5 times.
6. Allow the vehicle to roll down from 6th gear to 1st gear with slight brake at least 5 times.
7. Complete WOT kickdowns from each gear at vehicle speed from 20KPH to 130KPH.
Best results will be obtained if the pedal is not started from 0%. I.e 20% to 100% pedal kick
down. Repeat this sequence of kickdowns 5 times.
