Ok,

I've got a 1998 Honda Prelude with a SS Auto transmission.

(I ***** about it enough, so I'm sure most of you know this.)

Anyway,

About 3 months ago the tranny started to hard shift from 3rd to 4th gear.

The odd thing is that it only hard shifts when I'm at WOT or 3/4 throttle doing about 5300+ RPM's in 3rd gear.

I've noticed on my tachometer that the RPM's have a tendancy to jump (or slip) upward when I'm hauling ass.

The transmission does not appear to be slipping though...

It got me to thinking:

The transmission is an electronically controlled beastie.

If the VSS (Vehicle Speed Sensor) was defective [had an intermittant problem at higher RPM's], might it cause a problem with the shifting of the transmission?

As I said, if I shift at 5500RPM from 3rd to 4th, but take my foot off the gas just before, the transmission shifts fine.

Any thoughts on this would be REALLY appricated.
