Well sorry to hear your tranny is about gone but Good Job breacking into the 13's with 3.08s. It sounds like your head bearing is about ready to go, this is on the imput shaft. That front bearing starves for fluid by bad design. That is the same thing that happened to mine Kev, but mine expolded and took out the imput shaft. I bought the rebuild kit from D&D $149.00 and a new imput shaft for $99, now Don Jr. didn't reccomend putting in a new imput shaft with a old cluster gear, the gear is $180. I rebuild it 4 years ago with a new shaft after I broke 3 teeth off power shifting. THe tranny ran fine and I never had a problem till now. It took a lot of miles and abuse these last couple years so take it apart and look at the gears if the gears look good and are in tolerance I would just rebuild it.
