I got a bit concerned about the transmission shudder so I headed over to Ford to have it checked to make sure it's not something else.
After they checked that everything was in good working order, I was surprised to find out that you had a "procedure" to do to make it adapt to our conditions.
It is as follows:
DPS6 6 Speed Powershift Transaxle
* Drive the vehicle to perform adaptive strategy learn on a level road surface
1. Depress vehicle brake pedal (do not use parking brake)
2. Shift to Drive
3. Wait 15 seconds
4. Shift to Reverse
5. Wait 2 seconds
6. Repeat steps 1 to 5 Ten (10) times.
7. Accelerate from a stop with light throttle to 15mph (24kph)
8. Brake gently to a complete stop (allow at least 6 seconds)
9. Repeat steps 7 to 8 five (5) times
10. Accelerate from a stop with light throttle performing 1-2, 2-3, 3-4 shifts maintaining 1700 to 2000 rpm.
11. Accelerate to a speed between 50mph (80kph) and 65mph (104kph), achieve 6th gear, keep throttle steady with engine below 3000rpm for a minimum of two (2) minutes.
12. Repeat stepp 11 two (2) times.
* NOTICE: If a drive cycle is not completed, the customer may feel erratic shifts and driveability concerns.
I am going to do this whole thing, but my only issue with it is I can only do this on NLEX, SCTEX or new SLEX. I can't think of any stretch of road that allows me to do step number 11 consistently.
The other thing I took note of is that the technician informed me that if I replace/remove the battery, this needs to be redone again as sort of a reset to reconfigure the computer box.
Well, I hope this post helps other Fiesta 1.6S AT owners. =)
