Folks, I did the powerflex tranny mounts, and now after putting everything back together I have a terrible shriek. Switched from Alta IC boots, back to stock because we thought the Alta ones got pierced. Can't locate the EXACT spot of the shriek but when pressure is applied to the IC and drivers side horn, it seems to fade a little. So pressure on the drivers side relieves it a bit. Video to come.

 

At first I had a CEL. Now I do not. Uploading the video and will post a link.

 

Here is the noise.

 

We fixed it... Don't ask. Doofus friend took bolts off and couldn't remember where...

 

Doofus Friend... We've all got them...
Only problem with mine is, he's invisible and only seems to help out when I'm working alone....

 

haha

Glad to hear you fixed it! It is usually a seal issue with those clamps and the boots if the sound is off the charts.
