SHIFT SHOCK WHEN SHIFTING INTO 3RD, 5TH AND/OR R
Last Issued: 06/04/2020
APPLICABLE MODEL(S)/VINS
2017-2020 Mazda6 (Mexico spec)
DESCRIPTION
Some customers may complain of a shift shock felt when shifting into 3rd, 5th and/or R range with no A/T
related DTC stored. The symptom can be temporarily repaired by A/T initial learning procedure, but may
recur after multiple driving cycles.
Applicable situations:


Shifting up: 2-3, (4-5)
Shifting down: 4-3, (6-5)
NOTE:(4-5) and (6-5) are felt more than others due to the gear ratio.

Shifting into R: D-R, N-R, P-R
Improper control logic of the TCM may cause improper learning of R-3-5 brake engaging speed during
certain driving situations. To correct this concern, the control logic of the TCM has been modified.
Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
1. Verify customer concern.
2. Reprogram the TCM with Mazda Modular Diagnostic System (M-MDS) using IDS-114.06 or later
software and TCM Reprogramming Procedure below.
3. Perform “Initial Learning” according to the instructions on MGSS (INITIAL LEARNING).
4. Perform “N-R learning”.
a. Verify the ATF temperature reached 60°C {140°F} or over.
b. Shift the selector lever to N position
c. Shift the selector lever from N to R position and wait for five seconds.
d. Shift the selector lever from R to N position and wait for five seconds.
e. Repeat the steps (3) and (4) five times or more.

5. Verify repair.
TCM REPROGRAMMING:
ATTENTION: READ ALL NOTES AND CAUTIONS BEFORE REPROGRAMMING TCM!
CAUTION:
• IF IDS DOES NOT HAVE SUFFICIENT BATTERY POWER, THE REPROGRAMMING WILL FAIL.
•TCM DAMAGE MAY OCCUR IF THE CORRECT BATTERY CHARGER SETTING IS NOT USED.
• SET THE BATTERY MANAGEMENT SYSTEM TO "POWER SUPPLY MODE" DURING TCM
REPROGRAMMING.
• POWER SUPPLY MODE will maintain proper battery voltages during TCM reprogramming.
• If a different charger is used, MAKE SURE IT DOES NOT EXCEED 20 AMPS. IF IT EXCEEDS 20
AMPS, IT COULD DAMAGE THE TCM.
• The charger MUST be connected directly to the vehicle battery.
• It is NOT necessary to remove any fuses or relays during TCM reprogramming when the IDS screen
prompts you to do so. You may accidentally stop power to one of the TCM terminals and CAUSE THE TCM
TO BE BLANKED, or you may receive error messages during the IDS reprogramming procedure.
• Start/Stop button vehicles: DO NOT press the start/stop button during the reprogramming process.
BEFORE REPROGRAMMING TCM:
NOTES:
• Verify the current TCM file name in the vehicle by log view screen. If it's the same as shown in the chart(s)
below (or a later one), you do not need to reprogram the TCM.
• Always update the IDS tool first, then follow on-screen instructions to download the needed calibration file
for TCM reprogramming.
• If the vehicle exhibits any trouble codes or driveability symptoms, diagnose and repair using MGSS
BEFORE attempting to reprogram the TCM.
• When reprogramming a TCM, IDS will always display the “latest” calibration P/N available for that vehicle.
If any calibration has been revised/updated to contain new information for a new service concern, it will also
contain all previously released calibrations.
• Confirm the DLC cable is in good condition before attempting to reprogram the TCM.
TCM REPROGRAMMING:
1. Reboot the IDS to clear memory before reprogramming.
2. Using the latest IDS Software available, reprogram the TCM to the latest calibration (refer to “Calibration
Information” table) by following the “Module Reprogramming” procedure.
3. Verify the file name matches with the Calibration chart(s) below.
4. Clear all DTCs.
5. Start the engine and confirm that no warning lights stay on.
6. Record the customers radio presets from the infotainment system.
7. Disconnect the negative battery cable and wait at least 30 seconds to reset the fuel control learning data.
8. Re-connect the negative battery cable.
9. Re-enter the customers presets into the infotainment system.
