can you make a 3200 stall for a Duramax. have a suncoast stage 5 trans. had a 1057 converter in it. called suncoast pd $800. difference for a new converter a 1055 that was supposed to be a 2600 stall, but after a few runs it was only a 1700 stall. talked to suncoast they said the lady that did own suncoast sent a few converters out that was mislabeled. new owners don't act like they want to help. I've been telling everyone for the last 4 years how good suncoast trans. are. guess thats going to change.
