Hi,
The oil leak won't affect the transmission. However, if it is leaking on something that is extremely hot, it could cause a fire.
As far as the shudder stop, yes, it is a temporary fix, but it would help eliminate a possibility.
As far as the scanner is concerned, scanning the can-bus can retrieve codes from any of the control modules on the vehicle. If there is something in history, it should get that as well as pending codes.
