I took it by a transmission shop, hes 99% sure its a flexplate/TC noise. Its definitely more noticeable in reverse. Looking up videos on youtube for flexplate noises, it sounds just like it. Sound/noise coming right from the bell housing.
Its a brand new upgraded flexplate and torque converter. but possibly it cracked or something wrong with the bolts/mounting somewhere. Ill see if I can get it inspected sometime this week.
New engine
New "upgraded" flexplate (https://www.americanmuscle.com/sr-flexplate-6bolt.html)
New Torque Converter. The one I had in it was fine mechanically, but one of the threads for the TC bolts were messed up on removal of the engine. Looks like the last shop i had install the TC had a hard time with one bolt and forced it in. So that TC was not usable at the time.
New Torque Converter bolts. I triple checked which bolts to get with the torque converter company owner. Sent him a picture of them and he verified all good for clearance and grade.
Why would this happen? Only 1,000 miles into the new install.
