well i did infact break mine.
if these trannys are weak due to a high hp application, i believe my oem, spread bore, stock case 350 4mill would have smoked it right after assembly.
it did in fact break while downshifting between 4th and 3rd gear. i do not know the extent of the damage yet as i have not split the
cases yet. that joker was sure running great right before it broke though.
