Mazda 6 AT Warning

Hey guys,  i was driving my wife's Mazda 6 this
morning when the AT and ABS warnings popped
up. Upon reading the manual, i found that the AT
(Auto Transaxel) is actually an electrical issue.
Totally not what i expected!  I can work on trucks
all day long,  but im completely clueless when it
comes to cars,  especially crappy little foreign cars.
I read through most of the comments on here
about this particular issue,  and noticed that no
one really mentioned their brakes. When my AT
WARNING light comes on,  the car seems to be
reving itself,  and i completely lose my brakes, and
emergency brake as well. How are the brakes
being affected by an electrical issue?  I realize i
also mentioned the ABS light was on,  but the
manual suggests my brakes should still function
as normal. Yes,  my brake fluid is full.
