You ever figure this out?Ahh the party under the hood continues. I'm so frustrated I had to walk next door and slap the neighbor for walking out his front door and saying "that don't sound good". Here's what I know.... I dropped the transmission after the most respectable tranny shop in town told me I had a busted flexplate. With this info in brain, I quickly ordered another flexplate and put it in. I inspected the old flexplate, torque converter, bellhousing, input shaft, crank flange, ect.. and saw NO visible signs of damage PERIOD. By the way, this noise just happened one day with no warning or indication. I was sure the flexplate bolts or the starter ring was glancing off of the bellhousing or inspection cover causing noise, but there were no shiny spots to confirm this. Now the new flexplate is in and SAME noise is there. This morning I removed the bolts from the torque converter to the flexplate and started it up. I was hoping to eliminate the possibility of the torque converter being the culprit but instead I get the same noise. I looked before starting the motor, and had at least 3/16 clearance from the flexplate to the unbolted torque converter, so i dont think the two are slapping each other. Could my crank be warped? Rod bearings shot? Any Ideas where this noise is coming from??
