the transmission shop looked it over and said the band just broke. They also said the TC had a chunk missing out of the seal on the input shaft so I talked to ATS and they said i could trade my transmission and stuff i have now for all new and go with the 5 star converter. Probably going to end up doing that since it won't cost me much different than having the shop labor and stuff anyways. Raybestos said they only have seen one other band break so the transmission shop is sending it to them for inspection. I told them what HP and torque i was making and they said it really shouldn't have broke anyways. ATS also said the band was a quality one and should have held up.
The stock strut was used and should have asked more questions before this so I could have got the HD strut.
