In the last few months, the automatic transaxle has started behaving strangely, meaning un-requested shifting, momentarily into another gear. Because the car is driven always with the overdrive on, the shifting must be into a lower gear. At first the phenomenon only happened one of two times during a 10 ten mile drive, but she had our local trusted auto garage inspect the operation of the transaxle and do a flush job on it. The auto guys there could find no problem, or did not experience the un-requested shifting.

The phenomenon is happening more often now, maybe six times during a 30 mile drive and it seems to be correlated with the following driver actions: switching from low beam to high beam head lights, switching on the turn indicator , changing the wind shield wiper speed, turning on the cruse control on or off, We are waiting for the intermittent action to happen enough so that if we give the car to the auto garage again, they can experience it and get some insight. The Overdrive button works OK, as does the light. I am theorizing that a sudden change in electrical voltage make be causing the action, but it is a feeble attempt at understanding the issue. If any one has any insight, we would like to here it
