MULTI-MODEL (WITH SKYACTIV-DRIVE A/T) - VEHICLE SPEED DOES NOT INCREASE WITH ENGINE SPEED AND ATX DOES NOT SHIFT UP OR DOWN
BULLETIN NOTE
This bulletin supersedes the previous bulletin 05-008/13, issued on 12/12/13. The APPLICABLE MODEL(S)/VINS has been revised.
Changes are noted below in Red.
APPLICABLE MODEL(S)/VINS
2012-2014 Mazda3 (with SKYACTIV-DRIVE A/T)
2013-2014 CX-5 (with SKYACTIV-DRIVE A/T)
2014 Mazda6 (with SKYACTIV-DRIVE A/T)
DESCRIPTION
Some vehicles may exhibit the ATX fail-safe function working with the following symptoms:
The vehicle speed does not increase with engine speed
The ATX does not shift up or down as expected
The condition may not always be able to be reproduced and DTCs may not be stored when the vehicle is brought in. Foreign material (iron particles in the ATF) may enter the ATX valve body and cause a temporary malfunction of the valve body and/or sensor (ATX fail-safe function activated). The fail-safe function is canceled without DTCs recorded if the malfunction goes away and does not occur again at the next drive cycle.
Fail-safe function operation:
If a technical fault is detected in the ATX by the malfunction detection function, the fail-safe function limits the ATX control (inhibits some gears or shift down functions).
Even in case of an ATX malfunction, the fail-safe function allows minimum vehicle driveability.
Customers having this concern should have their vehicle inspected/repaired using the following repair procedure.
Just want to say hi to everybody; long time reader, first time posting.
My 2014 cx5 gt FWD just had this transmission problem yesterday. Exactly as described!!
This TSB is not complete, seems there should be repair procedure following the last sentence.
Just wonder anybody has any idea what the repair procedure will be? Whether this repair will be covered by the power train warranty? My 3 yrs/ 36,000 miles warranty already expired.
Thanks in advance for any help.
My cx5 has only 17,000 miles. Really disappointed
