Whinning noise when acceration. Engine accelarates fine but there is also a whinning noise

ok make sure the knock and ping is from the engine, noise can also be from the transmission very common in automatics

usually a secondary ignition problem(coil pack, spark plug cables).

Is it over filled?

You cold try cleaning the valve body

I guess you have a modulator,is that
leaking fluid,pull of vacuum hose & check

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.

The most common whining noise from that tranny is the transmission pump. Sometimes they have a high pitch whine noise yet nothing wrong its normal. Sometimes its an indication of the pump being over-worked due to a dirty filter or fluid low. Turn engine on and check tranny fluid level. If low add to cold mark on dipstick, check for leaks under vehicle. If fluid appears very black or burnt smell, recommend flushing fluid and replacing filter (located inside tranny pan) yours will be a 4L60E type tranny.

AOD transmissions are known for the P.R. valve causeing buzzing, whinning noise etc. Lift the truck up try to hear the noise first. Drop the pan check for excessive metal shavings. Fords are also bad about engine noise. Vacuum noises, fan clutches, etc...

fuel pump

the gears are not moving when the car is in park, therefore, no noise from the trans.. it is coming from somewhere else. quite possibly, it's the starter motor is continuing to spin. have someone listen under the hood while starting. if it is the starter, the noise will be more prominent when listening from under the hood. how long does the noise last?

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.)
