Thanks all and especially to 69A100...my best friend and Brother for adding some more to this issue. I am inclined to agree with most here that it is something related to the Torque Converter, Flex Plate and that general area. I had trouble when I had to re-build the motor this last time around getting the Flex Plate off of the Crank. I "tweeked" it in getting it off but was able to straighten it out...or at least I thought so...and then re-installed it. It had some 'flashing" on it that I cleaned up with a file...no grinding...but here is the kicker I think. I bought it from the eBag a number of years back and it was most likely a used piece. But at the time I was "cobbling" parts together as this car didn't come with a drive train. So...With that in mind, just for the sake of conversation, would you swap it out for a completely new one, and see if that is the culprit? It will be an "*** PAIN" to drop the tranny myself but I have a tranny shop that will look of the 727 and address the slippage issues I have with it. My thinking is, at that time they can replace the flex plate with the new one and then run their pressure, and shifting checks. Otherwise, I drop it and lay on my back...Man that S**T is getting old...to replace it. I would rather pay to have it done as opposed to my doing it myself, but I will if I have to. Also...I have been looking at some of the newer SFI Flex Plates, and although a little more pricey than the stock units, appear to be of better quality. Who here has experience with them, and what would your recommendations be? Torque Converter is a Stock set up. Although that also might be a culprit in this noise...:eusa_wall:
