Default Car shudders in high gear under load - transmission?

My '95 SE shudders & vibrates when in overdrive or high gear when car is under load, like when going up a hill. It doesn't take much of a load to start the shuddering. I get it to stop by stepping on the gas so it downshifts, or letting of the gas, then stepping on it again so it goes into a lower gear and gets the RPM up. I'm assuming it'* something in the transmission!? It was doing it when I got the car at 122,000 miles. It now has 143,000 miles. Anybody have any idea what this might be? Thanks.

DOES THE SES LIGHT COME ON, MIGHT BE SOMETHING AS SIMPLE AS A RESTRICTED FUEL FILLER AND RUNNING LEAN UNDER LOAD

The whole car just seems to shudder. Not like a tire out of balance. Hard to describe, shudder, vibration, rumbling, etc. I don't think it'* the engine pinging, seems to be too heavy of a noise for that. I think it'* the transmission rumbling somehow!?

I don't have a scan tool. No light comes on when it'* doing it. Excuse my stupidity, but what is the SES light?

Yup.

A scantool would save your butt right now. Too many variables. How old are your basic tuneup items?

I changed the spark plugs about 17,000 miles ago, nothing else was changed. I have not replaced the fuel filter, don't know if it ever was.
