Sounds like you have air in your steering system. I would start by looking for any leaks on your steering system like hose to fitting crimps, steering pump, etc. Check your steering fluid level to make sure it is full and also look for bubbles on the dip stick. If everything looks good, start the vehicle and turn the wheels all of the way to the left and then to the right. Do this while the vehicle is in park and repeat at least 5 times. This will work out any air in your steering system. If the problem persists then the power steering pump may need to be replaced.

You need a full service of the auto transmission. Check the oil condition for burnt smell.
The oil may be burnt out and fails to lubricate when temperature goes up.
But most likely the gear gaskets or gear teeth are worn out.
