Hoping I can get some new ears on this noise to send me in another direction. My Cobra is TH400 swapped and has been making this noise for 2 years. It has a new SFI flexplate and new ARP hardware for both flexplate to crank and converter to flexplate. This noise has been the same the whole time no matter what I do. I even put a new starter on it thinking that was the issue. Noise goes away once you get above 1500rpm.
My thinking is since the converter to flexplate connection is a nut/bolt setup, I’m unable to get enough clamping force and the two are moving ever so slightly at idle since the mounting holes are slightly larger than the bolts (by design). Think this is possible?
Any thoughts or opinions are appreciated!
