I believe we call that a planetary gear, found in the rear of the transmission. Its gone.

Look for vacuum leaks had a similiar problem in my car. a small split in a hose can cause havoc, and is usually only noticeable at low revs, like changing gears in an auto and sitting at a set of traffic lights.

It can be a long process checking all the hoses but it will give you a good look round the engine.

Pull the dipstick, engine running in park. If the level is too low or too high, adjust it. But it sounds like your main concern will be the condition of the fluid. Look at it, smell it, feel it. Is it black? Does it smell like burning? Is there shavings in it? If you said yes to any or all of the three, your tranny's fried. Have it rebuilt, replaced or buy a new vehicle, whichever is more cost evective.

Generally there is something wrong that makes the engine too weak for that resistance of putting it in gear.
That could be a misfiring cylinder, an intake manifold leak or cracked hose, a bad sensor like temperature, etc.
Does it idle smoothly?
It is better after it warms up?

But another possibility is that the tranmission is not going into the right gear. Try putting it into low instead of drive.
Of the torque converter bearing could be siezed, and not allowing the normal slippage it needs.

Have you checked the fluid levels in the transmission?
