check your rear engine mount.

sounds like it could be the ball joints binding up

Sounds a lot like a wheel balance problem, Does vibration go away over 55? In checking driveshaft joints...If you looked at them with the vehicle in park with the wheels on the ground, the shaft is "loaded" and cannot be correctly checked. To do this properly, vehicle should be in neutral with both rear wheels off the ground. Sometimes a joint can appear to be tight but still be bad. Check for traces of powdered rust around the rubber boots right where the end caps meet the cross on the inside. Any rust there indicates lack of grease and the likelyhood that the joint is frozen.
Check both balance and joints. Good luck.
Don't forget to rate my answer after you find the problem.

IF GEAR SHIFT SHAKES THEN THE TRANSMISSION MOUNTS COULD BE BAD. HOPE THIS HELPS. GOOD LUCK

on both my Camrys, i had this problem. You could really notice it when you were driving down the road going 40-60 mph and punch the gas - car would vibrate, let off the gas - vibration stops, punch the gas - car vibrates...... On both, it was the CV joints. It is much easier to just replace the drive axles (with the new cv joints and boots already installed). For my last replacement, i think thy were only around $65 each.
