You might have a u-joint issue, probably the front one. None of the transmission gears are loaded when running in high, which suggests the problem is elsewhere. Synchronizers might be able to cause the symptoms. I'd take the clutch housing cover off and rotate the engine and check that all of the clutch cover to flywheel bolts are secure, and look for anything else that might be out of place. The snubber and all motor mounts need to be in place and secure. A u-joint with a dry bearing or defective bearing can cause a "kick" every time the driveshaft revolves. This is usually more prominent under load, and may cause an annoying vibration at higher road speeds.
