found this also......................NOTE: The loss of drive in positions "D", "D3" or "D2" failure symptoms suggest that the first speed freewheel has failed. This can occur if "D" is engaged while the car is rolling backwards causing overload of the freewheel and subsequent failure. Transfer box chain slip can also cause this fault by providing shock loads to the transmission. In positions "D", "D3" & "D2" the freewheel holds the torque when accelerating from rest. In position "D1"the freewheel is supported by engagement of a clutch (to provide engine braking). This will "lock" the freewheel even if it has failed, allowing the car to pull away normally.
CAUTION: Oil levels must be checked COLD with engine running. Refer to TIBs 44/01/99/NAS and 44/01/98/NAS as well as Service Alert SA0015GI-15 for additional guidance.
5. Fault reference #3: If loss of drive in positions "D", "D3" or D2" is determined but the vehicle drives when in "D1" or when reverse gears engaged, perform the following:
^ On electronic transmissions the stall speed monitoring fault code should be recorded in the fault memory (P0722, Bosch, 27 GEMS).
^ The oil may look clean and smell normal with this fault.
^ Check oil level and record results on ATER.
6. If the fault is still present after checking/correction of oil level AND the fault occurs every time acceleration from rest is attempted, replace transmission and flush oil cooler lines....
