Small rattle coming from the transmission area

[AZ_S550]

So after I got my headers installled and after about a week I started hearing a small rattle at low rpms and during light acceleration. Haven’t been under the car yet but has anyone had any issues with the torque converter going out. I only have 7500 miles on mine with FBO and e85 tuned by PBD. Thanks In advance

Check the trans block spacer plate, it’s a common issue across the S550 and F150 platform:

Also check the emergency brake cable and attaching assembly found under the driver side trans tunnel. This has been a known source of metallic rattle as well and is hard to replicate unless in a certain RPM range. The cable is loose and raps against the trans tunnel under certain conditions OR could be touching exhaust mid pipe. How to adjust the cable and assembly:

if looking at both from under the car, yes visually they will look “fine”, but the Tech (or DIYer) needs to take a closer look to make sure both are not a source of the rattle.
