I've noticed that when I put my van in reverse it makes a
not-very-loud "ratcheting" sound, which lasts about a second, as it's
going into reverse. It's a 3.3 with auto overdrive.
I believe the transmission has been rebuilt by the dealership in the
past. The van has 142K on the clock now.
The noise is quiet enough as to only be noticeable when it's in the
garage and the windows rolled down.
Anyway, is this noise normal for these, or is it a sign of an
impending transmission problem?
