NOTICE No: MT000003754
MODEL: Mazda MPV YEAR: 2002
AFFECTED VINs: N/A
SUBJECT: 2-3 shift flare when cold
DETAILS:

Symptoms and Conditions

When the powertrain is cold and during the VERY FIRST 2-3 shift for the day, there may be a slight 2-3 shift flare (200-300 rpm) at light to almost half throttle.

And, there may also be a slight shift shock during a cold 2-3 backout (backing off the throttle slightly) during very slow speeds, like when driving in a parking lot situation.

After the vehicle is up to normal operating temperature, the flare and backout shock cannot be duplicated.

Repair Procedure

  1. Confirm the complaint and duplicate the condition. The ATX has "adaptive learning" and will not shift properly untill the vehicle has been driven at least 10-15 miles. Disconnecting the battery cable will cause the ATX to have 2-3 shift shock until it "learns" the driving pattern and has had time for clutch packs to properly seat.
  2. If the vehicle has been driven for more than 15 miles, the battery cable has not been disconnected, and the 2-3 slight flare can be duplicated each day, REPLACE THE TCM located under the passenger side carpet (below the glove box). The TCM is attached to the PCM using a bracket.
