Shift Elements, Position
NOTE:
Before carrying out repairs on the transmission, first carry out On Board Diagnostic (OBD). Diagnosis and Testing
When dealing with problems relating to poor acceleration and performance or general malfunctions, the following table indicates which selector elements are actuated in the various gears. This should help to identify the selector elements which are not working properly
