Its a low transmission/hydraulic pressure.First, make sure your transmission fluid level is at the full mark. Also check if fluid is getting leaked from the lines.It's possible the fluid may be getting too hot. Check to make sure your radiator fins are not clogged. Pull the screen in front of the radiator and clean it, flush the radiator with water from the backside, you may need to pull some shields from the side of the engine to do this. Also as you mentioned that you hear a noise,it can be bad pressure sensor. It is located on the front of the transmission, above the transmission filter. If you have a pressure gauge, you can verify if it has good pressure.Also for buzzing sound, flush the hydralic system and fill it with fresh oil and if that dosnt work take the pump out and flush it manualy. Check the oil condition and relief valve.If the valve is getting stick the clean the valve and if oil is very dirty then replace the oil.But if oil is replaced just few months before and looks good then no oil change is required.----------- check out.this troubleshooting will point towards the faulty part.This should help.Keep updated.Thanks.Helpmech.

There could be an air lock...... there should be a handle somewhere for a manual pump you can loosen a fuel line connection and pump until the bubbles stop and all fuel comes out.

Yikes, that sounds like an antifreeze leak. Most likely it is just a hose with a hole or crack. Lift the hood and try to see where it is coming from. One thing you must do is check the level of antifreeze or you could ruin the engine. If a red light comes on the dash, you will need to find a safe place to park and turn off the engine before it can overheat and be ruined. If you are not familiar with anything under the hood, you are best off taking it to an independent shop that has been recommended by another person.
