Noisy 6R80

[PIPO]

I bought a built Supra that came with a 6R80 tranny swap. The tranny is stock with the PHR install kit and US shift quick 6. Also a D circle 3800 stall converter. This thing rattles like crazy at low rpms in high gears. Just wondering if anyone has experienced this before?
I’ll remove the pan this weekend and see if there’s any metal shavings.

That is not normal if the trans doesn’t have the thermostat bypass you need to check the fluid level when it’s warm around 170

It should have. It’s bone stock. But we are dropping the pan tomorrow and checking converter bolts. I’m hoping the converter bolts are loose.

We dropped the pan and nothing out of the ordinary. The converter bolts weren’t torqued to spec, had the wriog trans filter but nothing changed, the noise is still there.
