It will not kick down with the foot switch, What would be the symptoms if the kick down solenoid was stuck?
Is there any way to check anything else without dropping the pan? and even if I drop the pan what should I be lookin for?

Solenoid problems usually prevent upshifts (by continuous keeping it downshifted).
Back to the start. Warm the car up real good, park it on level ground an check the fluid level..check it for discoloration or foul smell (I doubt there will be since you haven't experience flaring
AFAIK).
The only other thing I can think is the rear cover change which I believe covers the shaft and the governor linkage. as you probably saw from muleears thread a faulty governor will cause short shifting too. As I understand the hydraulics, the governor could allow too much pressure input into the valve body which will open up other "logic paths" and thus force the transmission to upshift.
There is a way to test governor pressure but no explanation that I've seen of how by a DIY'er.
As I offered muleears send me a PM with e-mail and I'll send you the better of the two diag manuals that I have.
You can remove the governor on the vehicle but it's more complicated than pulling the pan..quite honestly I don't even know what you could look for in the pan other than foreign debris.
As you've already done all the other work I have no doubt in your competence to play with the rest

The valve body, well some have gone there, few have come back.
