when they said the allison is a strong tranny,i'm here to say it is next thing to bullet proof..it will put serious fight up before it gives up..read my sig and believe me with the almost stock tranny and pushing an extra 300 to 350hp thru it plus the stock hp well i just don't know of a better tranny that would hold up to that kind of abuse  i don't do a whole lot of towing but i always put her in drive and never look back  92k and still runnin strong  hope this helps..
