TF904 Transbrake recommendation

The converter also needs to have Fins strengthened to handle any possible cavitation. I had a ten inch setup for transbrake use by TCI that wasn't done right, and looks like a gorilla with a big ballpeen hammer beat all the fins to death, I kid you not! They charged me $500 ( in 2000) and wouldn't fix it. Not that I hold a grudge much!!!
