After the car heats up to regular temp, I get a very hard vibration. The vibration stops after I've reached 1000 rpms, when in park or neutral, the vibration goes away or after reaching rpms above 1000 rpms. Changed motor mounts, took out the throttle body and cleaned it. Have been to five different shops and been looked at by 9 mechanics. They all seemed to find someway to get some money out of me but not the problem vibration. Want to keep this car, other than the above problem, great car. 27 and 35 miles per gallon. What to do next? Oh yeah, tranny was check and is great condition.

Just to be sure I understand correctly, you've got a vibration that only occurs under 1000 RPM engine speed whether you're in Park, Neutral, or any forward gear, stopped or moving, correct?

Check the engine oil level and pressure.

Where and how exactly do you feel the "Shaking. Hard vibration"?

The very hard vibration occurs when the car is at proper temp. When in neutral or park there is no vibration. Only when the engine is below 1000rpms and in gear. Drive or reverse. Two different shops did a wet and dry valve check and they were great. The last shop did up the idle a bit but

as soon as the car reaches right temp, and in gear, the problem returns. Thanks for your help.

Forgot to mention that the vibration is through the steering wheel and it is very intense. When the hood is up you can see and hear the vibration. Seems that the engine is out of balance. We do have good mechanics here but seems to have them befuddled.

More, also had a full tune-up done. You can see how I went through so much money. Total of $1100 on different things but still the hard vibration.

The fact that it only occurs while in drive or reverse leads me to believe it is transmission-related. If it was a power steering pump, which I thought when you said you feel it through the steering wheel, it would be park and neutral too. If it was in the engine or on the engine, such as a harmonic dampener, it would also be all the time, not just drive and reverse. Check the transmission mounts and the transmission fluid.

Got another suggestion this morning from another mechanic. He said it may be the counter balance shaft. He said my engine does not have one. He is the same person who serviced the transmission and said it was in fine condition. I have been grasping at any suggestion for the last two years. All of mechanics that looked at the Camry said to just drive it and it would be fine. To stop the heavy vibration when stopped, I sometimes shift to neutral or keep the idle at or above 1000rps by pushing the accelerator, that's two years of that game. Really want to find the problem and get it fixed. Thanks again. Rick

I doubt it can be the counter-balance shaft when your engine was never equipped with one.
