    JMS LaunchMax Transbrake for 6R80

    How hard is it on the transmission? I searched on this forum and online (Mustang6G) and saw instances where the drum expanded cause transmission failure. Not sure how common this failure occurs. May be it has to do with power level? I'm NA with bolts ons and a 5C. I want to add this but concerned about how likely transmission failure might be. Anyone have any input on this? Thanks in advance.
