1997 Honda Accord Transmission shudder

Trans shudder from 3rd to 4th when going uphill slightly, seems to be have to let off gas.

I was hoping there might be some remedy for this other than a rebuild. I don't drive far to work, so in one spot where it might shudder I move it to D3 when turning slowly. It's tolerable, but has anybody else ever seen this? If so, what did you do to fix it?

Thanks alot for your help!
