Thunk on 2nd to 3rd shift

I bought a 2002 GT a couple of months ago. When up shifting from 2nd
to 3rd at high RPMs > 4500 I get a thunk sound and it feels like the
stick jumps out of 2nd gear. During normal driving I don't notice it.
I have a couple of months left on the warrantee so I will have the
dealership look at it. Has anyone else experienced this? What was
wrong?

Thanks,
Mark

Could be slack in the driveline. Hard to say from that description.

have someone put the car up in the air and check the usual things
first thing I'd check is trans mount and slack in the u-joints. engine
mounts too. then go from there.

When you DO figure it out, let us know.
It might help someone else find a mystery noise.
