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 following serial numbers: •7TN0820364 and higher \(CX\-3\) / 8TN1090104 and higher \(except CX\-3\) •8TR1008883 and higher •8TD1003276 and higher •8T50331192 and higher \(CX\-3\) / 8T50329705 and higher \(except CX\-3\).
