ENGINE , most likely is this. open hood and see LEAK , i bet. here.

check alt bearing,open hood & listen while running,turn off engine and remove drive belt then start engine to see if noise goes away.

You have a leak in the power steering system. It should be easy to find just look for where the fluid is dropping onto the ground below the vehicle while parked, then look under the vehicle to see where the leak is coming from. Make repairs as needed.

Gday mate,geoff here, sounds like you are low on transmission oil, check if the level is low, do this with the engine running in park with the handbrake on, also if the oil is not red but has been "burnt" and is brown, it will need to be changed, hope this helps,geoff.

MANUAL TRANSMISSION OIL GOT TOO LOW.CHECK MANUAL TRANSMISSION FLUID SOUND DRY.

check fluid level when car running, sounds like a pump wine, is it slight or annoying? you could try lucas oil trans medic additive as well as a trans fluid change. Get opinion from a reputable trans shop, or just drive and ya never know.

Fuel pump is in the gas tank.

Thank you for getting back to me. I would like you to check your transmission fluid. start the engine and let it warm up at idle speed for about 15 min and check the fluid. It sounds like you do not have enough in it, there for the whining noise with increase of speed since your transmission is speeding up with the rate of your vehicle. If this does not help and the problem persist please let me know. If the noise you were hearing was coming from the u joints of the vehicle it would not make a whining noise with increase of speed. The u joints will only make a noise when they are going bad when the vehicle is shifted into any gear from the shifter( EX: park to drive, park to reverse ECT.)

Try changing the oil and filter in the trans...use an additive such as lucas along with the oil. If the noise is from something minor that may help. Otherwise, you will need someone to run it on a lift and see just where the noise is coming from.

sound like internal problem like tranny oil pump gear or torque converter noises.
