No, I don't hear it when the vehicle is stopped.

I had pulled the stick when cold and thought there might be a problem. The fluid had looked dark reddish brown and I thought I saw particles in it. Just a few minutes ago I did the level while warm and running an the fluid looks fine. The level is halfway through the "X" area.

What do you think about Lucas Transmission fix? I do drive about 80-115 miles a workday. My home is in the Pocono mtns of PA so I do a lot of up/downhill and curves.
Thanks!

those trans fix things are not necessary, if there is something wrong it needs to be taken out and rebuilt, there is nothing in a can that would help. also doesent sound like a trans issue. sounds like bearings or something loose. most likely bearings. with the wheel in the air see if you can move it 12 to 6, there should be no play. if not check over everything in there for something loose, broke or worn end links etc..

Wheel bearings tend to get louder the faster you go, usually loudest around 30-40 mph....is that one of the symptoms? Does the noise vary when slightly turning the steering wheel slightly left and then right, at 40 mph?

I didn't know about that. Part of the problem with trying to hear noises, even with the radio off, is all the other noise. Wind noise being the biggest but I'll make a point of listening for this.
Thanks!

The noise does not vary turning right/left. When increasing speed the winding repetition does increase. It is also higher in pitch but I also can't call it a "whining" noise. "Whining" being how some have used to describe transmission noise.

OK, found out it was the winter tires.
But now I still get a bump or a kick in the rear when starting out. But I'll start that question over on it'* own thread. Thanks everyone!

There was another post about a transmission issue and I searched out an item called "Trans Tune" by Sea Foam. Below is a direct quote from their website, and I put the URL to the page in the 'Trackback' below this text box.

◾erratic shifting
◾sluggish shifting
◾“sticking” for a second or two before engaging the next gear
◾engaging the next gear with a jolt

…then your automatic transmission could benefit from a Trans Tune treatment. These symptoms can be caused by varnish and moisture build-up (erratic or sluggish shifting), clogged valve bodies or sticking electric solenoids in the transmission (slow or jolting engagement). Trans Tune can help remedy these conditions.

Since that description "engaging the next gear with a jolt" sounds exactly like my van I'm going to do that first. Then put on another 17K (if the problem doesn't reoccur) until my mileage goes over the 150K mark and get a full service on it. It will certainly be due by then.
I'm thankful for everyone who has contributed to this thread. I'll update when I've got something to report.

Thanks!
