You`re ahead of the game if your gonna get it scanned. In 94 most powertrain codes won`t turn on the check engine light, but they will be stored in memory.
Bob is right about there being a range of causes, if you get it scanned and get any codes post them back here and I can hopefully point you in a direction. Be sure to get the code numbers, not the definitions, the def varies from tool to tool.
Also with a scan tool he should be able to enter the datastream(watch all the sensors and peramiters). Depending on the tool there should be one for TCC slip RPM, if when the truck is vibrating that RPM climbs up over 75 or so, more than likely your converter is causing the vibration.
Another not so sure fire way to tell if the converter is causing the vibration is to get up to speed(get it to start vibrating)then while holding your foot steady on the gas, press your other foot lightly on the brake. If the engine RPM jumps up a bit and the shudder stops, more than likely it`s in the converter. I should say that you eliminate the driveline(ujoints,dif). What you are doing is activating the brake switch and that signal releases the converter lock-up clutch..
Sorry for the long post, these naughty buggers are my life, so I can tend to get long winded.
In my opinion this is a great transmission. Much better than the 700R4, just don`t tell Allan I said that..SSSSHHHHHHH Good Luck BW

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
