Buzzing sound coming from my 4l60e I have a 4l60e behind my carbed LS1 controlled by the TCI EZ-TCU and the remote TPS cable. When I turn the key on I get a strong buzzing sound from the trans and it goes away when I open the throttle and comes back at idle. I have calibrated the TPS and it still makes the buzzing sound even when running.Any help would be great. Thanks

Sounds like the electronic pressure control solenoid doing its job. I wouldn't worry about it. They pulls more at lower pressure because they are dumping off pressure and pulse less at higher throttle angles. HTH Vince

Great thanks. Now the buzzing comes and goes. Just didn't want to ruin anything in the tranny.
