Default Is it the Converter???

Hey guys,
A buddy of mine works at a VW dealership and they just got a 2001 Corvette for a trade-in a couple weeks ago. Its an automatic with 103,000 miles on it. When the car is started and sitting at idle it has a bad whinning sound coming from the area of the converter. I was wondering if anyone has had the same problem or might know if the whinning sound is something other than the torque converter. They gave the guy $12,000 on the trade and they took it to auction and they couldnt get rid of it. Also, if it IS the converter, how much does a torque converter run for a C5?
Thanks Guys
-Fred-

Well I'm not sure about the converter and the sound, but I can estimaqte the cost of the converter and the repair if that is the only problem.

Labor to pull and replace it is probably going to be about $700.00.
Fluid and shop supply's $100.
Torque Converter $200 - $800 depending on if you chose original equipment / after market or performance.

So cost to replace at the lower end from a reputable shop would be about $1,000 and about $1,600 on the high end.

Pull the pan and change the filter and fluid and make sure they change the O ring that the filter plugs into.

There should be no rotation in the converter if the car is an automatic sitting in park

That car must be a real "*****" because right now at the auctions C5's and C6's are bringing blood. In fact, I brought a 97 torch red coupe with 92k miles up last week and it did $12,700

Thats not correct. The converter is always turning when the engine is on.
Anyways,
the whining sund you hear is most likely not the converter but the transmission pump that gets driven by the converter. Its a vane pump and might be on its way out. I would pull the transmission and inspect the pump.

You do know that the transmission and converter are in the back of the car.
Where location wise is the noise coming from. I have never have heard of a converter making whine. Could also be bearings in the torque tube.
When I replace mine I installed a Vigilante 2600 stall. I think it ran around $800. Well worth the money.
