What would cause my transmission to not engage any gears?
I was driving my 2007
chevy impala ls the
other day when I down
shifted to first but when
I went to put back in
drive nothing
happened. I tried every
gear and the motor just
revs up and nothing
happens. The tranny
never shifted hard or
clunked. It had plenty
of fluid but the fluid
was really dark. I am
pretty mechanically
inclined but have never
messed with a tranny
before. Need help
please!!!!
