TPS? TCU? Shake at 45mph

89 jeep XJ 4.0 auto 4x4
No lift (yet)

My jeep is/was shaking/vibrating at 45-50mph so I unplugged the TCU and shifted it manually. It ran smooth as silk with no shake.

From my understanding this means my transmission is mechanically fine. It also means the solenoids are fine because when they go bad it won't shift correctly at all.

So my first assumption is the TPS needs adjusting or just a replacement. Does this sound correct, and any other suggestions?
