I have the same problem. I talked to Suncoast and they told me there are 3 sets of bearings in there and 1 of those could be bad. SO you will have to srop the tranny again and send it in. Mine did it from day 1 and now I have 15,000 miles on it and it still does good, no motivation to rip the tranny back out! Does it only do it at high rpms?

Mine seems to have a whine also. I suppose it could be the power stearing pump but it sounds like the tranny. Mine has always had this noise and with 40k on now I am not going to worry about it. I just sold my edge and my bully dog and ordered the PPE so I am not sure how much abuse my trans will take anyhow!!!:D
