This bulletin applies to Mazda Tribute, model years 2001-2005. When diagnosing drivability or fuel/emissions-related DTCs, inspect the engine air filter and air inlet system carefully. Symptoms may include rough/low/erratic idle, engine stalling or hesitation, or the engine warning light not turning off.
Some 2011 Mazda Tribute vehicles equipped with a 6F35 automatic transmission may exhibit an intermittent harsh 1-2 shift or harsh 5-6 shift regardless of temperatures or soak time. Additionally, 4-5 shift flare may be experienced after an extended cold soak. 2.5L equipped vehicles with late 4-5 shift events/high rpm's may also benefit from this calibration update.
