I am confused why a Transmission is needed vs a new differential.
Except my driveshaft broke at the Top near the Trans and damage my Trans.
Since you race your Hellcat you could have an upgraded Trans like I do.

There also could be other suggestions, for what you need.
You could also ask them about used Trans too.
Sometimes the Speedshops have them because customers upgrade.
I wish you Good Luck
