I have a 2007 Ford Edge with automatic transmission. As of this past two weeks or more and even after a lub, oil and transmission service the transmission shakes/studers around 1500 rpm. The transmission fluid was low. The auto speed is not necessarily the issue rather it is RPM of the engine and the low demand on the transmission (low demand) that somehow triggers a studder/shake around 1500 rpm and I can see the tachometer needle vacillate at times. Any sense as to what is causing the shuddering at 1500 rpms and what/how is wrong and what is to be repaired?
Thank you,
