| well i ran 500rwhp thru my stock allison for about 4 months and it wouldn't have been much longer before it went kaboom,runnin on that high setting i would say you can do it for quite a while but one day it mite surprise but it be a week from now or year from now so what i'm trying to say is start saving a lttle cash every month for the next year and then do a stage 3 or stage 4 tranny and that will take care of all your issues..also if you wanted to run it below 90hp extra and you could probalily run it for years like that..hope this helps and again this is only my thoughts.
