I've posted here once or twice before, and I'm hoping that I can rely your
expertise and great advice again.

My '97 Explorer Sport (90K) seems to have some transmission problems, and
before I call the mechanic I thought I'd see what you all thought.
It worked fine earlier in the day, but when I went to tuck it into the
driveway last night I pulled it forward, which worked fine, but when I put
it into reverse, nothing. It acted as though it was in neutral. I tried all
of the gears, but same thing, it lets me select the gear, but then acts the
same as in neutral. The engine seems to run fine, and the shifter feels the
same as it always has, it just feels like it may not be engaging??

I apologize, I know little to nothing about transmissions, hence my
posting here. I'm hoping that someone can tell me what the problem might
be, and more importantly how serious/fixable this is. Is there anything I
can try before having it towed over to the garage? Many thanks in
advance!!!
