My 2007 CX9 is having a problem changing from 6 gear down to 5 gear on the freeway. When I am cruising along in 6 gear and I want to accelerate to pass someone. It changes down with a very hard banging , and in one case jumped straight into neutral, at 6o mph. It only does it from 6 down to 5. and not in any other change . The guys at the transmision repair shop cannot find anything wrong with it, because nothing comes up on the computer.
Has anyone else had this problem and know how to fix it?
Thanks for any help BruceSee also: Transmission Fluid Level Check Mazda CX-9 (2007-2014)
