- DSCF4399.JPG (0/2) Spare Trans Part

I'm hoping somebody has seen this before. I was performing a 60K mile
service on my 2002 4.6L Expedition automatic transmission-fluid, filter
and gasket. The transmission is a 4R70W, which I believe is also used
with the Explorer 4.6L V8, which is why I'm posting to this group. When
I dropped the pan I heard something rolling around in it. I've attached
a pic of the part. Small bobbin like plastic piece with an O ring,
about 1.75" long. I stared at the tx for quite a while without figuring
out where it had come from. The tx shifts fine, before and after the
service, but I'd sure like to get the part back where it belongs.
Anybody have any ideas?

Another question. 1996 Explorer, 4.0L V6, 127K miles. Engine runs great
except at 2K RPM, or about 40mph, when I'm not accelerating. At this
time it will "hesitate" for lack of a better word. It does not feel
like an ignition miss. If I accelerate, no problems, but it tends to
not run smoothly with a steady gas pedal. Plugs and plug wires are
new, and I've run several iterations of fuel injector cleaner through
it. No codes on the OBD-II. I also recently cleaned the MAF with no
change.

Thanks in advance.

Sounds like a plug for the dipstick hole thats pushed into the pan on
assembly. All it means is the pan has never been dropped before. Not
needed, throw it away.

That makes sense, it's the same diameter as the dipstick hole now that
I think about it. That leads me to believe that the previous owner
probably did not perform the scheduled 30K mile trans service. I bought
the vehicle with 42K miles.

Thanks, I appreciate the advice.
