very slight vibration on light acceleration to 2 gear, like a fan belt whir-then gone
If that occurs in the 25-40 mph range, could be associated with the torque converter lock-up function. Does the sensation seem similar to crossing a traffic lane that has a bevy of those little hemispherical bumps on the lane-marker?

Means nothing. Ignore it until (or if) it gets worse.
How many miles on the vehicle??
Do you feel the vibration in the steering wheel, seat, pedal(s), mirror(s), cup holder area??
Have you had any work done on the vehicle shortly before you noticed the vibration??
Is it a 2wd or 4wd/awd vehicle??
Does it make noise when you feel the vibration??
About what MPH does it happen??
Is it consistent and can you duplicate it anytime you want??
52000 miles
only from a complete stop to 1st gear change, otherwise smooth
it is slight and feel like a fan belt would feel if loose-its not
Have you changed the transmission fluid? At 52,000 miles it’s a good time to do it regardless of whether it solves the problem or not. It might help though. A couple more questions: AWD or RWD and 4 or 6 cyl engine?
Thank you for answering 2 of 7 questions but with out being able to drive the vehicle it can be very difficult to diagnose, even driving it it can be hard, so the more info we know the more out you are to find the problem…
You have me confused on the feeling a fan belt slip, I don’t remember ever feeling one slip only hearing it slip, could you elaborate a little more on that??
Does it do it as soon as you start moving or at a certain speed?? Does it do it every time or just every now and then???
Have you had just had the tires rotated??
