Automatic Transaxle System -- Manual Shifting Test



MANUAL SHIFTING TEST
The purpose of this manual shifting test is to determine whether a problem is caused by either mechanical or electrical factors. Disconnecting the transmission wire disables electrically-controlled automatic gear shifting. In this case, operating the shift lever is the only way to shift the transaxle gear. If the gear is not changed by shift lever operation, it is assumed that there is a mechanical problem.
