i took my car in for a service @ 49000 miles, with complaints of loss of power (intermittent, but noticeable at times) and an oil leak from teh bell housing. they singled out the oil leak as a reverse swich on my transmission that was apparently known to leak. when i picked up my car they said they didnt find anything in relation to a loss of power. when i left the dealership i hit the nearest freeway and at about 55 mph i began to hear a loud shrieking/harmonic tone- it got so loud i couldnt hear the person sitting next to me when she talked. the sound increased in volume and tone as i gave it more gas, and when i put in teh clutch and revved the sound would immediately quit. i turned around and brought it straight back to the dealer, but they seem to have no idea what it is. any thoughts/ similar experiences?

 

Did they forget to refill the transmission?

 

Clutch worn out?

 

found out it was the rear diff. apparently the whole western half of the united states is out of them too, as i have been told im on back order for as much as 5 weeks.
