Whining noise near Torque Converter
Hello,
I have a '96 LS400 with 170,000 miles and am getting this whining noise from the bell housing near the torque converter.
The noise is the loudest when I start the car when it is cold. Once it starts to warm up, the noise decreases. But when the engine is reved up to about 2000 rpm in park, the noise comes back.
When driving, the whining could be heard. The transmission shifts fine without any issue. But occasionally when coming to a complete stop, a clunk is heard and the rpm drops to about 150 rpm causing the car to shake a little.
I went underneath the car and am hearing noise near the torque converter. It sounds like a seized bearing. Is there a bearing near the torque converter? Is this what happens when the torque converter is bad? I did a transmission fluid flush at 155,000 miles with the factory fluid and the transmission is shifting fine so I don't think the transmission is the problem. I would like to hear your opinions. Thanks for your time.

i agree with grand ls... transmission mount.
or if its not that id say the torque converter is shot... which shouldnt really be an issue unless if this thing was drived hard etc...
if it is, the best replacement out there is the one from lextreme
