Hi,
I have a 2003 Mustang GT Automatic Transmission with 80k miles.
When driving, if I punch the throttle, the car will downshift after a second or so, and it slams when doing so. The slam feels to be in the rear end. It doesnt have any problems downshifting regularly, and upshifting is ok.

Does anyone have an idea what this could be? I have researched and not found much on this issue for SN95s.
