Two problems related to transmission gear slipping have been reported for the 2006 Mazda MAZDA6. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2006 Mazda MAZDA6 based on all problems reported for the 2006 MAZDA6.
When accelerating or climbing enough to invoke a downshift, the transmission occasionally slips or disengages causing very high rpm, followed by a sudden downshift and very hard jerk. It almost feels like being hit from behind. This failure poses an extreme rear end collision hazard. Mazda has issued TSB 05-016/06 to deal with this problem but my dealer informed me that Mazda now recommends a complete transmission change in lieu of a valve body change recommended by the TSB. This transmission should be recalled, it's unsafe.
