TRANSMISSION SHIFT BUMP ON ACCELERATION -
20-30 MPH (32-48 KM/H) - BUILT BETWEEN
10/12/2012 - 10/31/2012
FORD:
2013 Fiesta
ISSUE
Some 2013 Fiesta vehicles built on 10/12/2012 and through 10/31/2012 may exhibit a transmission shift bump feeling on acceleration, noticed typically at speeds of 32-48 Km/h (20-30 MPH) A new calibration is available to alleviate this condition.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
1. Reprogram the powertrain control module (PCM) to the latest calibration using Integrated Diagnostic System (IDS) release 83.03 and higher. Calibration files may also be obtained at the website.
2. Using IDS, select the following:
a. Powertrain
b. Transmission
c. Clutch system test
d. Complete procedure
3. Using IDS, select the following:
a. Powertrain
b. Transmission
c. Transmission Adaptive Learning and perform each of the following:
(1) Transmission Range Sensor Adaptive Learning
(2) Shift Drum Adaptive Learning
(3) Clutch Adaptive Learning
(4) Exit
d. Perform Adaptive Drive Cycle. Refer to Workshop Manual, Section 307-11.
NOTE
FAILURE TO PERFORM ALL STEPS OF THE ADAPTIVE CLEARING ROUTINES AND THE DRIVE CYCLE MAY RESULTING ERRATIC SHIFTS AND DRIVABILITY CONCERNS.
NOTE
PLEASE ADVISE THE CUSTOMER THAT THIS VEHICLE IS EQUIPPED WITH AN ADAPTIVE TRANSMISSION SHIFT STRATEGY WHICH ALLOWS THE VEHICLE'S COMPUTER TO LEARN THE TRANSMISSION'S UNIQUE PARAMETERS AND IMPROVE SHIFT QUALITY. WHEN THE ADAPTIVE STRATEGY IS RESET, THE COMPUTER WILL BEGIN A RE-LEARNING PROCESS. THIS RE-LEARNING PROCESS MAY RESULT IN FIRMER THAN NORMAL UPSHIFTS AND DOWNSHIFTS FOR SEVERAL DAYS.
WARRANTY STATUS: Eligible Under Provisions Of New Vehicle Limited Warranty Coverage Warranty/ESP coverage limits/policies/prior approvals are not altered by a TSB. Warranty/ESP coverage limits are determined by the identified causal part and verified using the OASIS part coverage tool.
