Sharp stop while reversing in Tahoe,
What went wrong with my Tahoe
when, while reversing just now it
did a dead stop, made a noise and
jerked like I had hit something.
Now it will not reverse but does
go forward. For a few minutes
had a loud squeaky noise but that
is gone now. The shifter goes into
reverse and the car sounds like it
does when it is readying to go
move in reverse but it won't go.
Help please
