05001152022-06-06. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:LEVER AND LINKAGE:COLUMN SHIFT. Hard shifting/shift lever bebration
MT-014-172017-08-10. Service bulletin. ELECTRICAL SYSTEM; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ELECTRICAL SYSTEM:SOFTWARE. Whenever you are reprogramming a PCM or any other module, always use the GR8 Battery Charger in the Power Supply mode to prevent the battery from discharging.
SA-060-172017-08-10. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ELECTRICAL SYSTEM:SOFTWARE; ENGINE. Some 2012-2016 Mazda3s, 2013-2015 CX-5s and 2014-2015 Mazda6s may experience the Check Engine Light ON with DTC P0101 and/or P061B and/or driveability problem after reprogramming the PCM using IDS versions 105.02 to 105.04. If the PCM is reprogrammed with any software number included in the attached file and the throttle valve has too much carbon build up, the engine air amount calculation by the problem software may not be accurate. Perform the following Repair Procedure to correct this issue. NOTE Current version of IDS is 106.02.
05-002-15-3019F2017-06-08. Service bulletin. ENGINE; POWER TRAIN:AUTOMATIC TRANSMISSION. SOME VEHICLES MAY EXPERIENCE THE CHECK ENGINE LIGHT AND AUTOMATIC TRANSAXLE WARNING LIGHT ON WITH ONE OR MORE OF THESE DTCS STORED IN THE TCM MEMORY (P0842, P0847, P0872, P0877, P0780, P1738). • P0842:00 - OIL PRESSURE SWITCH NO. 1 (OIL PRESSURE SWITCH B) STUCK ON • P0847:00 - OIL PRESSURE SWITCH NO. 2 (OIL PRESSURE SWITCH A) STUCK ON • P0872:00 - OIL PRESSURE SWITCH NO. 3 (OIL PRESSURE SWITCH A) STUCK ON • P0877:00 - OIL PRESSURE SWITCH NO. 4 (OIL PRESSURE SWITCH B) STUCK ON • P0780:00 - GEAR SHIFTING MALFUNCTION • P1738:00 AUTOMATIC TRANSAXLE INTERNAL MALFUNCTION THIS IS CAUSED BY THE OIL PRESSURE SWITCH A AND/OR B AT THE CONTROL VALVE BODY TEMPORARILY OR PERMANENTLY GETTING STUCK DUE TO CONTAMINATION ENTERING THE PASSAGE. TO CORRECT THE PROBLEM, SOME MASS PRODUCTION CHANGES HAVE BEEN IMPLEMENTED TO REDUCE CONTAMINATION AND IMPROVE THE DTC DIAGNOSTIC LOGIC. NOTE: IF THE VEHICLE ALSO HAS A DELAYED ENGAGEMENT CONCERN, THIS TSB IS NOT APPLICABLE. REFER TO MS3 ONLINE INSTRUCTIONS OR WORKSHOP MANUAL FOR PROPER DIAGNOSIS AND REPAIR PROCEDURE.
05-001-15-31042017-06-08. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:GEAR POSITION INDICATION (PRNDL). SOME VEHICLES MAY EXHIBIT ONE OF THE FOLLOWING CONCERNS: • SOMETIMES THE SHIFTER MAY JUMP OUT OF 3RD GEAR OVER A ROAD BUMP WHEN ACCELERATING AFTER DECELERATION AT 25-40 MPH (40-65 KM/H) • HARD TO SHIFT INTO 3RD, 4TH, 5TH, AND/OR 6TH GEAR • SHIFT LEVER VIBRATES WHEN DRIVING IN 3RD OR 4TH GEAR THIS IS CAUSED BY INAPPROPRIATE TRANSMISSION INTERNAL PARTS.
05-005-15-3027A2017-06-08. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION; POWER TRAIN:AXLE ASSEMBLY. SOME CUSTOMERS MAY COMPLAIN OF A WHINING NOISE FROM THE AUTOMATIC TRANSAXLE WHEN DRIVING AT 10 MPH AND ABOVE. THE NOISE: • DEPENDS ON THE VEHICLE’S SPEED ONLY (THE MORE SPEED, THE MORE NOISE) • OCCURS WITH ALL TYPES OF DRIVING (ACCELERATION, DECELERATION, STEADY SPEED) • DOES NOT DEPEND ON RPM, GEAR, OR ATF TEMPERATURE. THIS IS CAUSED BY A DAMAGED BEARING IN THE TRANSAXLE DUE TO IMPROPER CONFIGURATION OF THE TRANSAXLE CASE. A MODIFICATION HAS NOW BEEN IMPLEMENTED ON AUTOMATIC TRANSAXLES WITH THE SERIAL NUMBER 3TR1111680 AND HIGHER OR 3TD1104906 AND HIGHER. THE SERIAL NUMBER CAN BE FOUND ON TOP OF THE TRANSAXLE CASE NEAR THE MANUAL SHAFT LEVER.

05-002-16-31292017-05-26. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION. THE NEW SKYACTIV-DRIVE FW6A-EL AT USES “AUTOMATIC TRANSMISSION FLUID (ATF) TYPE: FZ”. ONLY USE “ATF-FZ” TO FILL OR TOP OFF THE FLUID LEVEL. ATF-FZ IS SPECIALLY DESIGNED FOR USE IN THE SKYACTIV-DRIVE SERIES AT. IT IS A LOW VISCOSITY FORMULA WITH LESS FRICTION FOR BETTER FUEL ECONOMY. NOTE: ATF-FZ IS COLORED BLUE FOR EASY IDENTIFICATION. TO CHECK THE FLUID LEVEL, REMOVE THE BOLT, THEN REMOVE THE DIPSTICK. THE DIPSTICK IS MARKED WITH A “FZ” ON SKYACTIV-DRIVE FW6A-EL AT. WHEN FINISHED, INSERT THE DIPSTICK AND INSTALL THE BOLT.

05-006-12-2736A2017-04-26. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). SOME VEHICLES MAY EXPERIENCE EXCESSIVE SHIFT SHOCK OR A LONG TIME LAG WHEN SHIFTING FROM P TO R OR FROM N TO. THIS IS CAUSED BY MISS LEARNING OF THE TCM FOR SHIFT TIMING. TO CORRECT THE PROBLEM, THE LEARNING LOGIC OF THE TCM HAS BEEN CHANGED.
05-004-12-2706A2017-04-25. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION. SOME VEHICLES MAY EXPERIENCE AN EXCESSIVE SHIFT SHOCK AT ONE OR MORE OF THE FOLLOWING CONDITIONS: • WHEN SHIFTING FROM P TO R POSITION OR N TO R POSITION. • WHEN THE TRANSMISSION SHIFTS IMMEDIATELY AFTER STARTING TO MOVE (IN D POSITION). • WHEN THE TRANSMISSION SHIFTS AT CRUISING SPEED (IN D POSITION). THE INITIAL LEARNING MAY NOT HAVE BEEN COMPLETED AT THE TIME OF VEHICLE PRODUCTION. TO CORRECT THE PROBLEM, ONE OR MORE LEARNING PROCEDURES MAY NEED TO BE PERFORMED.
05-006-12-27362017-04-25. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). SOME VEHICLES MAY EXPERIENCE EXCESSIVE SHIFT SHOCK OR A LONG TIME LAG WHEN SHIFTING FROM P TO R OR FROM N TO R. THIS IS CAUSED BY MISS LEARNING OF THE TCM FOR SHIFT TIMING. TO CORRECT THE PROBLEM, THE LEARNING LOGIC OF THE TCM HAS BEEN CHANGED.
01-020-13-28162017-04-14. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM). SOME VEHICLES MAY EXHIBIT THE ENGINE RPM TEMPORARILY GOING UP ABOVE 3,000 WHEN THE ACCELERATOR PEDAL IS SLIGHTLY PUSHED WHILE SHIFTING AROUND 30 KM/H (19 MPH). THE ENGINE RPM RETURNS TO IDLE IF THE DRIVER TAKES THEIR FOOT OFF THE ACCELERATOR PEDAL. THIS CONCERN IS CAUSED BY IMPROPER CALIBRATION OF THE PCM FOR TORQUE TRIM CONTROL. TORQUE TRIM CONTROL IS USED ON THIS M/T TO ADJUST THE ENGINE RPM TO A SUITABLE SPEED FOR THE GEAR AFTER SHIFTING. THE FUNCTION ONLY WORKS WHEN THE DRIVER STEPS ON THE ACCELERATOR PEDAL WHILE SHIFTING TO HELP ACHIEVE SMOOTH SHIFTS. TO CORRECT THE PROBLEM, THE PCM SOFTWARE HAS BEEN MODIFIED.
05-002-13-27772017-04-14. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION; POWER TRAIN:MANUAL TRANSMISSION:LUBRICANT. ALWAYS BE SURE TO USE THE CORRECT AUTOMATIC TRANSMISSION FLUID WHEN REPLACING ATF. USING THE WRONG ATF MAY CAUSE SHIFT QUALITY COMPLAINTS OR MAY EVEN DAMAGE THE TRANSMISSION.NOTE:•ATF M-V (TYPE M5) IS NOT THE SAME FLUID AS MERCON®V OR MERCON®LV ATF.•ATF M-V (TYPE M5) HAS A GREATER VISCOSITY THAN MERCON®V AND MERCON®LV ATF IN LOW TEMPERATURES. •ATF M-V (TYPE M5) HAS A GREATER ANTI-JUDDER SPECIFICATION THAN MERCON®V AND MERCON®LV ATF.
