Hi guys I have a 2018 Charger Hellcat with 49,000kms and it's got a 2.5 Upper, 1440 Fic Injectors, Drop in Dual pumps and runs on E85. Started taking the car to the track more often and once i started creeping the high 9's i noticed a weird noise after my car shifts into 5th during my 1/4 mile runs. It sounds like it drops in power suddenly and doesn't want to continue climbing in RPM.

If anybody on this forum had similar experiences or knowledge on these transmissions could you please chime in. It is the stock hellcat transmission with a 2.62 rear.

I have linked a video with sound below.

The noise can be heard towards the end of my pass at 129mph.

All help and knowledge is greatly appreciated.
